INTRODUCTION AND IMPORTANCE
Primary adenocarcinoma of the renal pelvis is a rare and unique malignancy, representing a small fraction of renal cancers and posing significant diagnostic challenges due to its unusual presentation and similarity in symptoms to more common excretory tract disorders. This case emphasizes the importance of distinguishing this pathology from other renal neoplasms and metastatic adenocarcinomas that originate in the digestive tract.
CASE PRESENTATION
We report the case of a 34-year-old man with no significant medical history who presented persistent lower back pain but no hematuria, which is atypical for renal pathologies. Initial imaging identified a 30 × 14 mm enhancement mass in the right renal pelvis. Surgical intervention was performed through right nephroureterectomy, including excision of the bladder cuff. Histopathological examination confirmed the diagnosis of primary intestinal-type adenocarcinoma of the renal pelvis, characterized by necrotic carcinomatous proliferation with varying architectural patterns and occasional signet ring cells.
CLINICAL DISCUSSION
The diagnosis of primary renal pelvis adenocarcinoma is complicated by its nonspecific symptomatology and the potential for misdiagnosis as a more common urothelial carcinoma or a metastatic digestive-origin adenocarcinoma. Immunohistochemical staining supported a primary rather than metastatic digestive tract origin. This case underscores the need for a comprehensive diagnostic approach, including advanced imaging and meticulous histopathological analysis, to effectively differentiate this rare entity from other neoplasms.
CONCLUSIONS
This case highlights the diagnostic complexities and the critical need to be aware among clinicians about rare renal cancers such as primary adenocarcinoma of the renal pelvis. It also stresses the importance of interdisciplinary collaboration in the diagnosis and management of such rare cases, improving our understanding and requiring timely and accurate treatment.

This study aimed to examine the association between calcific rotator cuff tendinopathy (RCT) and nephrolithiasis and/or cholelithiasis. A case-control study was conducted on patients diagnosed with RCT between June 2016 and June 2022. RCT was confirmed by ultrasound, and patients were divided into 2 groups: calcific RCT (case) and non-calcific RCT (control). Data were collected retrospectively from electronic medical records and completed by phone calls, looking for a history of nephrolithiasis and/or cholelithiasis; based on clinical features or incidental findings on abdominal and pelvic imaging. A total of 210 patients with RCT were included. Among the 95 cases of calcific RCT, 43 had a history of lithiasis (45.3%) against 23 (20%) from the non-calcific RCT group (P < .001); 21 patients suffered from nephrolithiasis (22.1%) and 26 had cholelithiasis (27.4%) versus 10 (8.7%) (P = .006) and 16 (13.9%) (P = .015) in the non-calcific RCT group, respectively. Logistic regression showed that the independent predictors of calcific RCT included a history of nephrolithiasis (OR, 4.38; 95% CI: 1.61-11.92, P = .004) and a history of cholelithiasis (OR, 3.83; 95% CI: 1.64-8.94, P = .002). In patients with calcific RCT, the occurrence of lithiasis was significantly associated in the bivariate analysis with higher age, body mass index, fasting blood sugar, and HbA1c (all with P < .05), but only with the presence of another site of calcific tendinopathy than the shoulder (OR, 3.11; 95% CI: 1.12-8.65, P = .03) in the multivariate analysis. Nephrolithiasis and/or cholelithiasis are associated with calcific RCT, and their presence predicts calcific RCT at least 3 times. Further research is required to determine the common risk factors and preventive measures against lithogenesis in patients with calcific RCT, nephrolithiasis, and cholelithiasis.

Review
Gynecological emergencies can often present with a myriad of non-specific signs and symptoms, posing a diagnostic challenge to the clinician. They can be grossly divided into uterine or adnexal pathologies. Uterine pathologies can be secondary to intracavitary accumulation of blood [like in patients with transverse vaginal septum, Robert's uterus, accessory and cavitated uterine mass, unicornuate uterus with contralateral non-communicating functional horn], bleeding per vaginum [like in patients with retained products of conception, enhanced myometrial vascularity], pyometra [secondary to pelvic inflammatory disease, cervical obstruction secondary to benign and malignant causes] or complications of fibroids [like red degeneration, torsion of subserosal fibroid]. The adnexal pathologies can range from ectopic pregnancy in a urine pregnancy test (UPT) positive patient to haemorrhagic ovarian cyst, ovarian torsion, ruptured dermoid cyst and tubo-ovarian abscess in a UPT negative patient. Multimodality imaging including ultrasound (USG), computed tomography (CT) scan and magnetic resonance imaging (MRI) can narrow down the differentials and help in formulating an accurate diagnosis. The objective of this article is to familiarize the readers with multimodality imaging findings in common as well as uncommon acute gynecological emergencies and provide an algorithmic imaging approach for acute gynecological emergencies. USG is typically used as the first line diagnostic modality in diagnosis of acute gynecological emergencies. CT scan & MRI are helpful as a problem-solving tool in acute gynecological emergencies when USG findings are indeterminate.

INTRODUCTION
Fallopian tube cancer is a rare tumor, representing between 0.3 and 1.8 % of all malignant tumors in the gynecological sphere. Due to the proximity of the uterus and ovary, the diagnosis of primary fallopian tube cancer is very difficult to establish and relies on very strict criteria. The endometrioid form is exceptional and of controversial etiopathogenesis. Only a few cases have been previously reported. Diagnosis most often occurs incidentally during histological examination. This case presents a distinctive aspect with the rare occurrence of endometrioid-type fallopian tube cancer, notably associated with endometriosis, and initially misdiagnosed as an infected endometrioma. It underscores the diagnostic complexities encountered in identifying primary fallopian tube cancer.
CASE REPORT
We present the case of a 49-year-old patient, followed for chronic pelvic pain associated with menorrhagia. Imaging revealed a myomatous and adenomyotic uterus, a right ovarian endometrioma, and a left multicystic ovarian formation with thick walls, measuring 135 mm, requiring histological verification. She underwent an exploratory laparotomy. During the procedure, extensive retro- and supravaginal adhesive tissue involving the uterus, both adnexa, and the digestive tract was found. Careful adhesiolysis was performed. The left adnexa harbored a formation suggestive of an infected endometrioma. A total hysterectomy with bilateral adnexectomy and peritoneal washing was performed. The postoperative course was uneventful. Histopathological examination revealed an endometrioid carcinoma of the left fallopian tube, classified as pT1a according to FIGO guidelines.
DISCUSSION
Tubal cancer is a rare cancer of unknown etiology, underestimated, and sometimes confused with ovarian pathology. Preoperative diagnosis is difficult because the clinical presentation is polymorphic and imaging is nonspecific. The endometrioid form is exceptional and of controversial etiopathogenesis. Treatment mirrors that of malignant epithelial ovarian tumors, with prognosis depending on FIGO stage and histological type.
CONCLUSION
Due to its unpredictable nature, fallopian tube cancer should not be overlooked as a differential diagnosis for any adnexal mass.

BACKGROUND Persistent truncus arteriosus is a rare congenital cyanotic heart defect characterized by a single ventricular outflow tract. Without surgical intervention, it has a poor prognosis in infancy. Here, we report an adult female patient with uncorrected truncus arteriosus type I, who presented with acute-onset abdominal pain due to torsion of a small bowel gastrointestinal stromal tumor (GIST). CASE REPORT A 41-year-old woman came to our Emergency Department with acute-onset lower abdominal pain for 2 days. Congenital heart disease, truncus arteriosus, had been diagnosed at birth, and there had been no surgical intervention. Abdominal computed tomography revealed a 10×9×12-cm mixed-density mass in the pelvic capacity. Transthoracic echocardiography revealed a 33-mm ventricular septal defect. The ascending aorta originated mainly from the right ventricle, and the pulmonary artery originated from the beginning of the aorta (type I truncus arteriosus, according to Collett and Edwards classification). After a quick and detailed preoperative workup, the patient underwent tumor resection by open surgery with general anesthesia. CONCLUSIONS This is the first case to report emergency surgery for a patient with uncorrected persistent truncus arteriosus due to torsion of a small bowel GIST. A multidisciplinary team with deep understanding of the disease entity was crucial. By considering the fixed hemodynamic and respiratory physiology, overtreatment and unrealistic goals were avoided. Eventually, the patient was discharged after being hospitalized for 2 weeks.

INTRODUCTION AND IMPORTANCE
Ovarian fibromas are benign tumours arising from the connective tissue of the ovarian cortex, classified into three pathological subtypes: fibroma, thecoma, and fibrothecoma. Their diagnosis is complicated by their solid nature and potential association with ascites and pleural effusion, resembling Meigs syndrome. Elevated serum CA125 levels can further complicate differentiation from malignant ovarian epithelial tumours.
CASE PRESENTATION
A 37-year-old female from a rural area presented with a distended abdomen and weight loss lasting 2 months. Clinical examinations revealed a solid pelvic mass and diagnostic tests showed significantly elevated CA125 levels. Imaging suggested a large ovarian mass and surgical intervention confirmed a fibrothecoma of the left ovary. The postoperative course was uneventful, with subsequent resolution of ascites and pleurisy.
CLINICAL DISCUSSION
The diagnosis of ovarian fibromas/fibrothecomas poses challenges due to their asymptomatic nature, solid appearance, and occasional association with the Meigs syndrome. Elevated CA125 levels can mislead the diagnosis of epithelial ovarian carcinoma. The case underscores the importance of considering ovarian fibromas/fibrothecomas in the differential diagnosis of ovarian tumours with elevated CA125 levels, especially in women of reproductive age. The benign nature of these tumours necessitates a conservative surgical approach, emphasizing the importance of intraoperative frozen section analysis.
CONCLUSION
Ovarian fibrothecomas associated with elevated serum CA125 levels are rare. Their presentation can mimic malignant ovarian neoplasms, leading to potential diagnostic confusion. Surgical removal remains the treatment of choice, with a favorable prognosis post-surgery.

Observational Study
AIM
To study and compare the clinical and imaging characteristics of psoriatic arthritis (PsA) in men and women.
MATERIALS AND METHODS
The study included 956 PsA patients observed in the Russian register, 411 (43%) men and 545 (57%) women. The average age of men/women was 46.0±16.50/50.7±17.20 years (<0.001), the duration of PsA was 9.9±6.4/10.3±7.6 years (>0.05), the age at the time of PsA establishment was 37.1±12.30/41.8±13.5 years (<0.001). Rheumatological examination, X-ray of the pelvis, hands, feet were performed, the LEI, plantar fascia tenderness, body surface area (BSA), body mass index (BMI), CRP, were determined. Patients filled out assessment scales of pain (Pain), disease activity (patient global assessment of disease activity - PGA), questionnaires HAQ-DI. The indices of Disease Activity in PSoriatic Arthritis (DAPSA), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), criteria of minimal disease activity (MDA) were evaluated.
RESULTS
The following differences in the course of PsA in men/women were revealed: X-ray sacroiliitis was detected in 175 (42.6%)/153 (28.1%); <0.001; the presence of erosions of the joints of the hands and feet - 138 (33.6%)/170 (31.2%); =0.435; LEI≥3 - 34 (11.4%)/78 (20.9%); =0.001; Pain - at 48.5±22.60/51.5±22.80 mm VAS; =0.043; PGA - 50.2±23.07/54.0±21.91 mm VAS; =0.010; moderate and severe functional disorders (HAQ-DI) were more often observed in women (=0.002 and <0.001, respectively); the average value of DAPSA is 26.4±16.8/31.9±22.58; <0.001; average BASDAI value: 2.7±2.83/1.8±2.78; <0.001; MDA was achieved in 13 (3.2%)/22 (4.1%); =0.486; BSA>10% - 54 (13.1%)/102 (18.7%); =0.021; comorbid diseases - 154 (37%)/277 (51%); <0.001. At the time of inclusion in the register, the proportion of patients receiving biologic disease-modifying anti-rheumatic drugs was higher in the group of men.
CONCLUSION
Our data, based on a large cohort study, demonstrate that PsA debuts in women at a later age than in men, the course of the disease is characterized by higher activity of peripheral arthritis, more pronounced functional disorders and a high prevalence of comorbid diseases. This creates a heavier burden of PsA in women and indicates that gender is an important characteristic of the patient that should be used to predict the course, therapeutic response and progression of the disease.

PURPOSE
Image registration is a crucial component of the adaptive radiotherapy workflow. This study investigates the accuracy of the deformable image registration (DIR) and contour propagation features of SmartAdapt, an application in the Eclipse treatment planning system (TPS) version 16.1.
MATERIALS AND METHODS
The registration accuracy was validated using the Task Group No. 132 (TG-132) virtual phantom, which features contour evaluation and landmark analysis based on the quantitative criteria recommended in the American Association of Physicists in Medicine TG-132 report. The target registration error, Dice similarity coefficient (DSC), and center of mass displacement were used as quantitative validation metrics. The performance of the contour propagation feature was evaluated using clinical datasets (head and neck, pelvis, and chest) and an additional four-dimensional computed tomography (CT) dataset from TG-132. The primary planning and the second CT images were appropriately registered and deformed. The DSC was used to find the volume overlapping between the deformed contours and the radiation oncologist (RO)-drawn contour. The clinical value of the DIR-generated structure was reviewed and scored by an experienced RO to make a qualitative assessment.
RESULTS
The registration accuracy fell within the specified tolerances. SmartAdapt exhibited a reasonably propagated contour for the chest and head-and-neck regions, with DSC values of 0.80 for organs at risk. Misregistration is frequently observed in the pelvic region, which is specified as a low-contrast region. However, 78% of structures required no modification or minor modification, demonstrating good agreement between contour comparison and the qualitative analysis.
CONCLUSIONS
SmartAdapt has adequate efficiency for image registration and contour propagation for adaptive purposes in various anatomical sites. However, there should be concern about its performance in regions with low contrast and small volumes.

An ectopic kidney is a rare congenital defect that is often asymptomatic, but can be incidentally discovered during imaging examinations. Moreover, the morphological characteristics and laboratory features of ectopic kidneys are nonspecific, which may lead to misleading diagnostic approaches, particularly when there are additional factors, such as infection, obstruction, or other anomalies. A 43-year-old female presented with a mass in the left adnexal area. She had septate uterus and a history of congenital urinary incontinence. Ultrasound and MRI findings indicated that the mass was a cyst originating from the ovary. However, it is possible that the lump was derived from the urinary system. To confirm the diagnosis, laparoscopy was performed, followed by pathological examination, which confirmed the presence of an ectopic kidney with a single-system ectopic ureter. The patient underwent nephroureterectomy, and her symptoms successfully resolved, leading to a favorable prognosis. This case report highlights a rare case involving an ectopic kidney with a vaginal ectopic ureter that initially presented as an adnexal cyst and caused urinary dribbling. This case emphasizes the importance of early recognition and accurate diagnosis in women with similar symptoms.

We report a case of a 22-year-old female with pedal edema, hypokalemia, and hypertension. On suspicion of hyperaldosteronism, further workup was pursued, which only revealed a low serum adrenocorticotropic hormone (ACTH) and an inappropriately normal cortisol level after a 1-mg dexamethasone suppression test, suggestive of primary hypercortisolism. CT of the chest, abdomen, and pelvis revealed a left adrenal mass. Based on the clinical findings and biochemical abnormalities, we were expecting this tumor to be aldosterone-secreting, but both serum aldosterone and renin levels were normal in our patient. Eventual surgical resection confirmed initial suspicions of malignancy, as it was found to be adrenal cortical carcinoma. This case highlights the unusual presentation of this rare but aggressive endocrinologic neoplasm and the importance of its prompt diagnosis and treatment.
