Placenta accreta spectrum (PAS) disorder is one of the leading causes of peripartum maternal morbidity and mortality; its early identification during pregnancy is of utmost importance to ensure the optimal clinical outcome. The aim of the present study is to investigate the possible association of the presence and type/location of placenta previa on MRI with PAS and maternal peripartum outcome. One hundred eighty-nine pregnant women (mean age: 35 years; mean gestational age: 32 weeks) at high risk for PAS underwent a dedicated placental MRI. All women underwent a C-section within 6 weeks from the MRI. All MRIs were evaluated by two experienced genitourinary radiologists for presence, type (complete/partial vs. marginal/low lying), and location (anterior vs. anterior-posterior vs. posterior) of placenta previa. Statistical analysis was performed for possible association of type/location of previa with placental invasiveness and peripartum outcomes. Intraoperative information was used as a reference standard. Complete/partial previa was detected in 143/189 (75.6%) and marginal/low lying previa in 33/189 (17.5%) women; in 88/189 (46.6%) women, the placenta had anterior-posterior, in 54/189 (28.6%) anterior and in 41/189 (21.7%) posterior. Complete/partial previa had an at least 3-fold probability of invasiveness and was more frequently associated with unfavorable peripartum events, including massive intraoperative blood loss or hysterectomy, compared to low-lying/marginal placenta. Posterior placental location was significantly associated with lower rates of PAS and better clinical outcomes. In conclusion, the type and location of placenta previa shown with MRI seems to be associated with severity of complications during delivery and should be carefully studied.

Internal hernias are difficult to diagnose clinically, and normal cross-sectional imaging has been documented in many patients. Transmesenteric hernias from congenital defects or prior abdominal surgery are most common. A 46-year-old previously healthy female presented to the emergency department with acute onset nausea and vomiting eight years after a right ureteral transection during a laparoscopic hysterectomy, with a delayed ureterolysis and reimplantation into the bladder. Rectal contrast CT scan demonstrated a partial large bowel obstruction that was unclear if it was due to an underlying mass, stricture, or internal herniation. The patient was taken for exploratory laparotomy which demonstrated redundant transverse colon herniated under the mobile right ureter; an extended right hemicolectomy was performed. This report describes alteration of retroperitoneal anatomy creating a potential space for colonic herniation and emphasizes that clinical suspicion must remain high for patients presenting with obstructive or partially obstructive symptoms.

Frontiers in Medicine 2024Malignant tumors of the ureteric bud are not common, and cervical involvement is even rarer. So far, there have been no such cases in the literature.
BACKGROUND
Malignant tumors of the ureteric bud are not common, and cervical involvement is even rarer. So far, there have been no such cases in the literature.
CASE SUMMARY
A 50-year-old woman developed intermittent light bleeding in the past 7 months and lower abdominal pain in the past 2 months. The human papillomavirus 16 (HPV) DNA, P16 chemical staining, thinPrep cytology test (TCT), and cervical and cervical canal tissue biopsy were all negative. Pelvic color Doppler ultrasound exhibited incomplete mediastinal uterus and heterogeneous echo from the cervical canal to the posterior wall of the cervix. Pelvic contrast-enhanced CT showed left cervical mass, left retroperitoneal mass, absence of the left kidney, and mediastinal uterus. An increase in human epididymal protein 4 (HE4) (133.6 pmol/L) was detected, while other tumor markers were at normal levels. Based on these examination results, a diagnosis of "cervical fibroids, left retroperitoneal mass, incomplete mediastinal uterus, left kidney deficiency"[SIC] was conducted, and expanded hysterectomy, right adnexectomy, and left retroperitoneal mass resection were performed. Through intraoperative rapid pathological diagnosis, postoperative pathological diagnosis combined with the re-evaluation of laboratory, and imaging and intraoperative examination results, the patient was diagnosed with ureteric bud intestinal-type adenocarcinoma involving the cervix. The patient has been tracked and followed up for approximately 11 months. She underwent six courses of chemotherapy. At present, the medication has been discontinued for 4 months, and there is no recurrence, metastasis, or deterioration of the tumor.
CONCLUSION
For large masses of the cervix, it is feasible for the operation to be performed, improving the prognosis. There were a few limitations. A preoperative aspiration biopsy of masses was not performed to differentiate benign from malignant. Preoperative urography was not performed to clarify the function of the malformed urinary system structure. Partial cystectomy should be performed simultaneously with the resection of the ureteric bud for intestinal-type adenocarcinoma. In this case, a partial cystectomy was not performed, which can only be compensated with postoperative chemotherapy. Moreover, this patient did not undergo genetic screening, and it is currently unclear whether there are any genetic mutations associated with ureteric bud intestinal adenocarcinoma.

Review
BACKGROUND
Uterine necrosis is a rare condition and is considered a life-threatening complication. However, cases of uterine necrosis were rarely reported, particularly those caused by infection. In terms of treatment, no minimally invasive treatment for uterine necrosis has been reported, and total hysterectomy is mostly considered as the treatment option.
OBJECTIVE
The article specifically focuses on minimally invasive treatments and provides a summary of recent cases of uterine necrosis.
CASE PRESENTATION
We report the case of a 28-year-old patient gravid 1, para 0 underwent a cesarean section after unsuccessful induction due to fetal death. She presented with recurrent fever and vaginal discharge. The blood inflammation markers were elevated, and a CT scan revealed irregular lumps with low signal intensity in the uterine cavity. The gynecological examination revealed the presence of gray and white soft tissue, approximately 5 cm in length, exuding from the cervix. The secretions were found to contain Fusobacterium necrophorum, Escherichia coli, and Proteus upon culturing. Given the patient's sepsis and uterine necrosis caused by infection, laparoscopic exploration uncovered white pus and necrotic tissue openings in the anterior wall of the uterus. The necrotic tissue was removed during the operation, and the uterus was repaired. Postoperative pathological findings revealed complete degeneration and necrosis of fusiform cell-like tissue. Severe uterine necrosis caused by a multi-drug resistant bacterial infection was considered after the operation. She was treated with antibiotics for three weeks and was discharged after the infection was brought under control. The patient expressed satisfaction with the treatment plan, which preserved her uterus, maintained reproductive function, and minimized the extent of surgery.
CONCLUSION
Based on the literature review of uterine necrosis, we found that it presents a potential risk of death, emphasizing the importance of managing the progression of the condition. Most treatment options involve a total hysterectomy. A partial hysterectomy reduces the extent of the operation, preserves fertility function, and can also yield positive outcomes in the treatment of uterine necrosis, serving as a complement to the overall treatment of this condition.

A 31-year-old female sought termination of pregnancy due to a fetal body stalk anomaly diagnosed at 18 weeks of gestation. Despite an anterior placenta previa, successful vaginal delivery occurred. However, placental adhesion over a previous cesarean scar occurred, and part of the placenta could not be removed. Immediate postpartum bleeding prompted imaging studies, revealing extravasation from adherent placental remnants. Uterine artery embolization (UAE) provided initial hemostasis, but recurrent bleeding necessitated re-embolization. Although conservative treatment was initially pursued, significant hematuria prompted reevaluation, revealing extensive uterine wall and bladder penetration. Surgical intervention with total hysterectomy and partial bladder resection was performed, leading to the successful recovery of bladder function following surgical repair. While this case achieved a positive outcome, there is a potential for permanent urinary dysfunction if lesions are more extensive. While achieving a conservative cure is ideal, it is essential to assess the timing for opting for surgical intervention.

Endometriosis is a complex condition causing surgical challenges, sometimes leading to urogynecological complications, the diagnosis and treatment of which are not always obvious. We present a case of a 46-year-old woman with a history of severe endometriosis and adenomyosis who developed an oligosymptomatic vesicovaginal fistula (VVF) as a complication of surgery. The patient's medical history included multiple surgeries for endometriosis, a cesarean section, and a laparoscopic hysterectomy. After the excision of the full-thickness infiltration of the urinary bladder, she experienced postoperative bowel obstruction treated by laparotomy. Subsequent urinary complications of bladder healing were eventually recognized as oligosymptomatic VVF. Symptoms of VVFs may vary, making a diagnosis challenging, especially when the lesion is narrow. Imaging techniques such as cystoscopy and cystography are helpful for diagnosis. The treatment options for VVFs range from surgical repair to conservative methods, like bladder catheterization, hormonal therapy, and platelet-rich plasma (PRP) injections, depending on the lesions' size and location. In this case, the patient's VVF was treated with PRP injections, a low-invasive method in urogynecology. PRP, known for its pleiotropic role, is increasingly used in medicine, including gynecology. The patient's fistula closed after 6 weeks from the PRP session, highlighting the potential of this conservative treatment modality.

Low-grade endometrial stromal sarcoma (LGESS) typically has a favorable prognosis. Hormone therapy is considered the first choice of treatment for recurrent LGESS. In this report, we describe a case of recurrent LGESS where hormone therapy was ineffective, chemotherapy showed a partial response (PR), and pazopanib resulted in stable disease (SD). A 50-year-old patient with LGESS underwent a simple total hysterectomy and bilateral adnexectomy (pT1aN0M0, stage IA). Five years later, pelvic tumors and ascites were observed. Exploratory laparoscopy revealed bloody ascites, an 8 cm pelvic tumor, and extensive peritoneal dissemination. Nuclear atypia of the tumor cells was mild, pleomorphism and mitotic figures could not be confirmed, and necrosis was not observed. Immunostaining was positive for CD10 and estrogen receptor, negative for the BCL6 corepressor (BCOR), and showed a low Ki-67 index. Fluorescence in situ hybridization (FISH) examination of the tissue showed rearrangement of the JAZF zinc finger 1 (JAZF1) gene. Multigene panel testing revealed a homozygous deletion of cyclin-dependent kinase inhibitor 2A (CDKN2A). Accordingly, the patient was diagnosed with recurrent LGESS and was treated with an aromatase inhibitor, followed by medroxyprogesterone acetate; both were ineffective. The patient had a PR to chemotherapy (doxorubicin/ifosfamide) and SD to pazopanib. The patient died 1.5 years after recurrence. In conclusion, we present a case of LGESS with a poor prognosis where hormone therapy was ineffective, and chemotherapy and pazopanib were both partially effective. The poor prognosis may have been associated with the CDKN2A homozygous deletion.

Adenocarcinoma, HPV-independent, mesonephric type (hereafter referred to as "mesonephric carcinoma") arising from the cervix is rare, its treatment has not been established, and its sensitivity to chemotherapy has not been fully investigated. Here we report on a 30-year-old female patient who presented at our hospital with a chief complaint of abnormal genital bleeding. We suspected cervical cancer. Based on examination, biopsy, and imaging, she was diagnosed with stage IIA2 adenocarcinoma of the cervix and was scheduled for surgery. Because she had a SARS-COV-2 infection, she was given two courses of paclitaxel-carboplatin (TC) therapy, based on the then-current surgical risk assessment after SARS-COV-2 infection, with a waiting period of at least 8 weeks. The patient was deemed to have a partial response and was treated with paclitaxel and carboplatin, after which she was deemed to have a partial response and underwent total hysterectomy. A diagnosis of stage IIA2 mesonephric carcinoma, ypT1b2N0M0, was made after histopathologic examination of an excised specimen. The patient was treated with 4 additional courses of TC therapy after surgery, and has had no recurrence in 13 months. We report a first case of response to neoadjuvant chemotherapy with TC regimen in a patient with mesonephric carcinoma of the cervix.

Review
BACKGROUND
Multiple studies have confirmed that programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1) is widely expressed in gestational trophoblastic neoplasia (GTN) tissues. Therefore, immune checkpoint inhibitors may be an option for the treatment of recurrent and drug-resistant GTN.
CASE
Four patients with recurrent or drug-resistant GTN who were treated with PD-1/PD-L1 checkpoint inhibitor agents combined with chemotherapy were reported. The mean age of recurrence was 45.8 years (35-56 years), including three cases of choriocarcinoma (CC) and one case of invasive mole (IM). International Federation of Gynecology and Obstetrics (FIGO) prognosis score: ≤6 (low risk) in one case, 7-12 (high risk) in one case, ≥13 (very high risk) in two cases. There were two cases of lung metastasis and one case of vulvar and inguinal lymph node metastasis. One of the four patients underwent total hysterectomy and one patient underwent resection of lung metastases. All the four patients received comprehensive treatment of immunotherapy combined with chemotherapy after relapse, among which one patient achieved complete response (CR), two patients achieved partial response (PR), and one patient developed progressive disease (PD). Three patients who achieved PR or CR were maintained by single agent immunotherapy after combination therapy, and there was no disease recurrence during follow-up. One patient with PD also achieved CR after using salvage chemotherapy after recurrence, and there was no disease recurrence during follow-up. During the treatment, four patients had different degrees of immune-related adverse reactions, all of which were grade I-II, and no severe adverse reactions were found.
CONCLUSION
Immune checkpoint inhibitors combined with chemotherapy has an impressive therapeutic effect on recurrent or drug-resistant GTN with mild adverse reactions, which can be used as a treatment option for such patients. However, due to the lack of large sample data support, the specific time and treatment course of its use, long-term use of adverse reactions and whether it affects fertility function remain to be solved.

Numerous studies have suggested a robust association between amylase and ovarian cancer. however, few amylase-producing ovarian cancers have been reported because amylase is a rare product of ovarian cancer. A case of an elderly female patient with an upper abdominal unfitness, intestinal wall along with uterine adnexal invasion, and high serum and urinary amylase is summarized in this article. The patient was initially suspected of having a gastrointestinal tumor. Initial laboratory findings showed markedly significantly raised serum and urinary amylase levels. Imaging showed invasion of the intestinal wall and uterine adnexa, and histology of the specimen taken through the abdominal wall lump and electron colonoscopy showed ovarian cancer. The patient's blood amylase levels decreased to normal after 4 cycles of neoadjuvant chemotherapy with paclitaxel and carboplatin. Following this, she underwent interval debulking surgery, which included total hysterectomy, bilateral adnexectomy, great omentectomy, appendectomy, resection of pelvic and abdominal lesions, and partial rectal resection. Postoperative pathology and immunohistochemistry staining confirmed a diagnosis of high-grade serous ovarian cancer. This case suggests that in female patients, hyperamylasemia may indicate the presence of ovarian cancer. It is necessary to perform a multisite, multipoint histologic examination to identify the tumor's origin in patients with multiple sites of invasion.
