The adrenal haemangioma, a rare benign vascular tumour, is increasingly detected through abdominal imaging. Just over 70 surgical cases have been reported since 1955. Their potential large size and overlapping imaging features with adrenocortical carcinoma poses a diagnostic challenge. Adrenalectomy is often needed for a definitive diagnosis due to inconclusive imaging. We report the case of a 61-year-old female presenting with an incidental finding of a right-sided 9.5-cm adrenal mass on imaging. Due to the risk of adrenocortical carcinoma with inconclusive imaging findings, an open right adrenalectomy was performed. The patient was discharged after 6 days with no complications. Post-surgical histopathology confirmed a diagnosis of adrenal haemangioma with a secondary adrenal pseudocyst. The presence of an adrenal incidentaloma with discordant radiological features proves to be a diagnostic conundrum. Therefore, in the setting of contradictory radiology and concerning mass size, we recommend adrenalectomy for definitive diagnosis of an adrenal haemangioma.

Hydatid disease is a zoonotic parasitic disease which rarely involves pancreas primarily. Diagnosis of pancreatic hydatid cyst is a challenge and operative skills are important to avoid spillage of cyst's content. A 19-year-old male patient was admitted to hospital with recurrent abdominal pain which was on epigastrium and left upper quadrant of abdomen. Pain was not associated with nausea, vomiting or fever. An abdominal computed tomography (CT) scan was ordered. As a result of abdominal CT scan, there was a cystic area in tail of pancreas with a diameter of 5.6 cm which includes septa and there was calcification on borders of the cyst. Possible diagnosis were either pancreatic hydatid disease, pancreatic cyst adenoma or cystadenocarcinoma or pseudocyst of autoimmune pancreatitis. Whole body positron emission tomography (PET-CT) scan showed no other cyst or lesion other than pancreatic cyst. Hydatid disease indirect hemagglutination test has been studied and it was positive. Imaging studies and laboratory results were suggested hydatid disease and laparoscopic distal pancreatectomy has been applied. Primary pancreatic hydatid disease should be in differential diagnosis when newly appearing pancreatic cyst has been diagnosed, especially in endemic areas. Appropriate surgical technique has to be applied to avoid dissemination of cyst's content.

BACKGROUND/AIM
Fibrin-associated diffuse large B-cell lymphoma (FA-DLBCL) is frequently associated with the Epstein-Barr virus (EBV) and manifests as non-mass-forming microscopic lesions within fibrin-rich lesions. Herein, we describe the cytological features of FA-DLBCL.
CASE REPORT
A 72-year-old man presented with a large retroperitoneal cystic mass that was treated by cyst aspiration and laparoscopic excision. Individually dispersed large, atypical cells in a necrotic background contained scant cytoplasm and hyperchromatic nuclei with irregular nuclear contours, frequent karyorrhectic debris, and mitotic figures. A fibrinous exudate with necrotic material attached to the inner surface of the cystic mass contained large, atypical cells that were individually scattered or arranged in small clusters. These were positive for cluster of differentiation 20 and Epstein-Barr virus-encoded RNA in situ hybridization.
CONCLUSION
We cytologically characterized FA-DLBCL as large, atypical cells that were individually scattered or arranged in small clusters in a necrotic background. To the best of our knowledge, we revealed the cytological features of FA-DLBCL.

BACKGROUND
Lateral window approach for sinus floor lift is commonly used for vertical bone augmentation in cases when the residual bone height is less than 5 mm. However, managing cases becomes more challenging when a maxillary sinus pseudocyst is present or when there is insufficient bone width. In this case, we utilized the bone window prepared during the lateral window sinus lift as a shell for horizontal bone augmentation. This allowed for simultaneous horizontal and vertical bone augmentation immediately after the removal of the maxillary sinus pseudocyst.
CASE SUMMARY
A 28-year-old female presented to our clinic with the chief complaint of missing upper left posterior teeth. Intraoral examination showed a horizontal deficiency of the alveolar ridge contour. The height of the alveolar bone was approximately 3.6 mm on cone beam computed tomography (CBCT). And a typical well-defined 'dome-shaped' lesion in maxillary sinus was observed on CBCT imaging. The lateral bony window was prepared using a piezo-ultrasonic device, then the bony window was fixed to the buccal side of the 26 alveolar ridge using a titanium screw with a length of 10 mm and a diameter of 1.5 mm. The space between the bony window and the alveolar ridge was filled with Bio-Oss, covered with a Bio-Gide collagen membrane, and subsequently sutured. Nine months later, the patient's bone width increased from 4.8 to 10.5 mm, and the bone height increased from 3.6 to 15.6 mm. Subsequently, a Straumann 4.1 mm × 10 mm implant was placed. The final all-ceramic crown restoration was completed four months later, and both clinical and radiographic examinations showed that the implant was successful, and the patient was satisfied with the results.
CONCLUSION
The bone block harvested from the lateral window sinus lift can be used for simultaneous horizontal bone augmentation acting as a shell for good two-dimensional bone augmentation.

INTRODUCTION
Non-pancreatic pseudocysts are rare lesions that typically form from the omentum and mesentery. These cysts have a thick fibrotic wall made up of fibrous tissue and may show signs of calcifications and inflammatory changes. The fluid inside them can vary, ranging from hemorrhage and pus to serous or sometimes chylous content. In most cases, these cysts appear as a result of trauma, surgery, or infection.
CASE PRESENTATION
A 35-year-old male patient from Ethiopia presented with swelling in his lower abdomen that had been present for 2 years. Initially, the swelling was small but gradually increased in size. The patient experienced frequent urination but no pain or difficulty during urination, urgency, intermittent urination, or blood in the urine. The swelling was initially painless but became painful 2 months prior to his presentation. Abdominal computed tomography scans revealed a well-defined, lobulated peritoneal lesion measuring 16 × 12 × 10 cm, consisting primarily of fluid-filled cysts with a thick, enhancing wall and septa. Additionally, there was a large, heterogeneous enhancing soft tissue component measuring 8 × 6 cm. As a result, the cystic mass was surgically removed in its entirety with partial removal of the bladder wall, and the patient was discharged in an improved condition.
CONCLUSION
Primary non-pancreatic pseudocysts are extremely rare lesions that must be differentiated from other possible causes of cystic lesions within the peritoneal or retroperitoneal regions. Surgeons should be aware of the potential occurrence of these lesions, which may have an unknown origin.

Two intact male dogs were evaluated for symptoms, including hematuria, prostatomegaly, anuria, lethargy, and abdominal mass. Presurgical evaluations, including complete physical examinations, blood examinations, abdominal radiography with contrast (only in Case 2), ultrasonography, and computed tomography and magnetic resonance imaging (only in Case 1), were performed. A paraprostatic cyst was diagnosed initially, and laparoscopic exploration and surgery were performed. Complete resection was performed in case 1, whereas partial resection with omentalization was performed in case 2. Histopathological examination of the tissue samples confirmed the presence of paraprostatic pseudocysts in both cases, with no evidence of an epithelial lining. These two cases represent the first documented instances of laparoscopic treatment for extraparenchymal prostatic cysts. The laparoscopic treatment proved feasible even in the case of a giant cyst causing anuria (Case 2). Paraprostatic cysts should be considered a potential differential diagnosis for abnormal urination accompanied by an abdominal mass, and long-term postoperative follow-up is necessary.

Turkish Neurosurgery 2024To evaluate the efficacy of percutaneous ventriculoatrial shunting as a salvage method for pediatric patients with abdominal complications.
AIM
To evaluate the efficacy of percutaneous ventriculoatrial shunting as a salvage method for pediatric patients with abdominal complications.
MATERIAL AND METHODS
Data obtained from 9 patients with ventriculoperitoneal shunt dysfunctions owing to abdominal complications, who underwent ventriculoatrial shunting as salvage treatment at a single institution between January 2019 and September 2021 were retrospectively analyzed. All operations were conducted under the guidance of intraoperative fluoroscopy and ultrasound.
RESULTS
The mean age of the enrolled patients was 8.1 ± 1.2 years (2-15 years). Six (67%) patients were male and 3 (33%) were female. The mean number of the patients? ventriculoperitoneal shunt revisions until atrial catheter placement was 7.5 times. The reasons for intraperitoneal catheter failure included peritoneal adhesions in 4 (44.5%) patients, pseudocyst formation in 3 (33.3%), and peritonitis in 2 (22.2%). Seven patients from the study cohort had no problem after ventriculoatrial shunt placement. Only 1 patient had shunt dysfunction related to the ventricular catheter, and ventricular catheter and shunt valve revision was performed 26 months after ventriculoatrial shunt placement. The atrial catheter of the patient was intact. One patient died from the progression of her primary disease (medulloblastoma in the 4 < sup > th < /sup > ventricle), which was unrelated to the ventriculoatrial shunt.
CONCLUSION
Percutaneous ventriculoatrial shunting under the guidance of intraoperative fluoroscopy and ultrasound is a safe, effective, and easy alternative in patients with peritoneal complications and a history of multiple operations.

This study aimed to automatically detect epiretinal membranes (ERM) in various OCT-scans of the central and paracentral macula region and classify them by size using deep-neural-networks (DNNs). To this end, 11,061 OCT-images were included and graded according to the presence of an ERM and its size (small 100-1000 µm, large > 1000 µm). The data set was divided into training, validation and test sets (75%, 10%, 15% of the data, respectively). An ensemble of DNNs was trained and saliency maps were generated using Guided-Backprob. OCT-scans were also transformed into a one-dimensional-value using t-SNE analysis. The DNNs' receiver-operating-characteristics on the test set showed a high performance for no-ERM, small-ERM and large-ERM cases (AUC: 0.99, 0.92, 0.99, respectively; 3-way accuracy: 89%), with small-ERMs being the most difficult ones to detect. t-SNE analysis sorted cases by size and, in particular, revealed increased classification uncertainty at the transitions between groups. Saliency maps reliably highlighted ERM, regardless of the presence of other OCT features (i.e. retinal-thickening, intraretinal pseudo-cysts, epiretinal-proliferation) and entities such as ERM-retinoschisis, macular-pseudohole and lamellar-macular-hole. This study showed therefore that DNNs can reliably detect and grade ERMs according to their size not only in the fovea but also in the paracentral region. This is also achieved in cases of hard-to-detect, small-ERMs. In addition, the generated saliency maps can be used to highlight small-ERMs that might otherwise be missed. The proposed model could be used for screening-programs or decision-support-systems in the future.

One frequent side effect of chronic pancreatitis is pancreatic pseudocyst. Abdominal pain and vomiting are common complaints that the patient presents with. However, atypical manifestations of pancreatic pseudocyst still confound medical professionals worldwide, making identification challenging and ultimately increasing the risk of fatal consequences. We describe the case of a 41-year-old man who had decompensated liver cirrhosis linked to alcohol intake. The patient presented with dysphagia and yellowish skin discolouration, which, upon further investigation, turned out to be peripancreatic pseudocysts extending into the mediastinum. Diagnostic challenges arose due to the rare occurrence of a pancreatic pseudocyst located in the mediastinum. Patient was treated with a culture-sensitive antibiotic and on follow up he was doing well.
