Abstract Leiomyosarcomas (LMS) of the ovarian vein are extremely rare and have a poor prognosis. Only 10 cases have been reported since 1977. The patient is a 69-year-old woman presented with right abdominal pain. Computed tomography showed a regularly shaped tumor, 80 mm in diameter in the retroperitoneum, adjacent to the descending part of the duodenum. Intraoperatively, the right ovarian vein was found to run through the tumor and was, therefore, resected together with the tumor. Pathological examination revealed a LMS of the right ovarian vein. Nine months postoperatively, multiple lung metastases were detected and chemotherapy was initiated. Delayed diagnosis is associated with high mortality. It is important that the diagnosis of LMS should be made preoperatively when you have already diagnosed a tumor to better direct the surgical approach. Multimodal therapy may improve prognosis.

Ovarian Vein Thrombosis

Ovarian vein thrombosis (OVT) is a rare medical disorder, which is most often found in the immediate postpartum period. OVT is rarely considered idiopathic. We report a case of idiopathic OVT with pulmonary embolism in a 33-year-old woman who presented with abdominal pain. Computed tomography and postoperative pathology confirmed the diagnosis of idiopathic OVT. To date, only 12 cases of idiopathic OVT have been reported. In this case report, we present a summary of these cases and a review of literature regarding management of idiopathic OVT.

To identify and localize an intraorbital wooden foreign body is often a challenging radiological issue; delayed diagnosis can lead to serious adverse complications. Preliminary radiographic interpretations are often integrated with computed tomography and magnetic resonance, which play a crucial role in reaching the correct definitive diagnosis. We report on a 40 years old male complaining of pain in the right orbit referred to our hospital for evaluation of eyeball pain and double vision with an unclear clinical history. Computed tomography and magnetic resonance scans supposed the presence of an abscess caused by a foreign intraorbital body, confirmed by surgical findings.

Intussusception is the most common cause of bowel obstruction in infants four to ten months old and is commonly idiopathic or attributed to lymphoid hyperplasia. Our patient was a 7-month-old male who presented with two weeks of intermittent abdominal pain associated with crying, fist clenching and grimacing. Ultrasound demonstrated an ileocolic intussusception in the right abdomen. Symptoms resolved after contrast enemas, and he was discharged home. He re-presented similarly the next day and was found to be COVID-19 positive. Computed tomography scan demonstrated a left upper quadrant ileal-ileal intussusception. His symptoms spontaneously resolved, and he was discharged home. This suggests that COVID-19 may be a cause of intussusception in infants, and infants presenting with intussusception should be screened for this virus. Additionally, recurrence may happen days later at different intestinal locations. Caregiver education upon discharge is key to monitor for recurrence and need to return.

Venous thrombophlebitis is an uncommon cause of fever and lower abdominal pain during the early postpartum period. It mostly occurs in the right ovarian vein, and computed tomography (CT) is useful for diagnosis. We present a case of thrombophlebitis of the renal capsular vein. A 27-year-old postpartum woman presented with right lower abdominal pain and fever unresponsive to antibiotics. Contrast CT showed a ring-enhancing mass in the right retroperitoneum, which was distinct from the right ovarian vein. Exploratory laparoscopy revealed a retroperitoneal hematoma and normal appendix. Reconstruction of CT images revealed that the mass was connected to the right renal capsular vein. Anticoagulation therapy improved the patient’s symptoms. Postpartum thrombophlebitis can occur at locations other than the ovarian vein, such as the renal capsular vein. If a retroperitoneal mass is discovered during puerperium, a thorough investigation of the mass’s continuity with surrounding vessels is essential to avoid unnecessary surgery.

Abstract Background Nutcracker syndrome is a condition in which the left renal vein is pinched between the abdominal aorta and the superior mesenteric artery, resulting in an increase in renal vein pressure and certain symptoms. We report a very rare case of retroperitoneal hematoma caused by the rupture of varicose veins of the left ovary. Case presentation A 77-year-old Japanese woman, para 7, experienced sudden left lower abdominal pain. She had no history of trauma or treatment complications. Computed tomography revealed a left retroperitoneal hematoma, but her abdominal pain subsided quickly; thus, urgent treatment was not required. We then scheduled her for an assessment regarding the cause of her bleeding. However, 6 days after the pain onset, abdominal pain symptoms recurred, confirming hematoma regrowth. Magnetic resonance imaging and three-dimensional computed tomography revealed an abnormal vascular network from the left side of the uterus to the left adnexa. Subsequent angiography revealed that the retroperitoneal bleeding originated from rupture of the distended left ovarian vein, which caused blood reflux from the left renal vein to the left ovarian vein. Although angiography confirmed a passage between the left renal vein and inferior vena cava, computed tomography showed obvious stenosis in the left renal vein. In accordance with these findings, we diagnosed the cause of the distention and rupture of the left ovarian vein as nutcracker syndrome. She underwent embolization of the left ovarian vein as hemostasis treatment, and had a good course thereafter. Conclusions This is the first report of a spontaneous rupture of the left ovarian vein caused by nutcracker syndrome. Nutcracker syndrome is not yet well known to clinicians and should be considered as part of the differential diagnosis when an abnormal vascular network in the pelvis is found.

Malignant mesothelioma is an aggressive cancer associated with asbestos exposure with median survival time of 8 to 14 months following diagnosis. Given that mesothelial cells also line the peritoneum and pericardium, malignant mesothelioma can present in unusual sites and in patients with nonrespiratory complaints. A 73-year-old male presented to the emergency department for worsening intermittent diffuse abdominal pain for the past 3 months with associated unintentional 40-pound weight loss, early satiety, and diarrhea. He denied exposure to asbestos. Computed tomography imaging revealed multiple masses concerning for malignancy including the primary retroperitoneal mass, a mass involving the terminal ileum, and a mass in the right upper lung. Esophagogastroduodenoscopy demonstrated significant mass effect within the stomach without signs of endoluminal infiltration. Computed tomography–guided biopsy of the retroperitoneal abdominal and intramuscular paraspinal masses was performed. Stage IV epithelioid mesothelioma was confirmed when hematoxylin and eosin staining revealed pleomorphic malignancy nuclei containing a vesicular chromatin pattern and prominent nucleoli and immunohistochemical staining was positive for CK Oscar, cytokeratin 7, GATA3, calretinin, EMA, and CK5/6. He was started on cisplatin, pemetrexed, and bevacizumab but developed severe abdominal pain with pneumoperitoneum and bowel perforation 1 month later and expired shortly thereafter. To our knowledge, this represents a highly atypical presentation of malignant mesothelioma considering the involvement of the retroperitoneum with diffuse lesions in the abdominopelvic cavity and thorax (sparing the lung pleurae). This case also calls attention to the occurrence of malignant mesothelioma in patients without known asbestos exposure and the crucial role of pathology in diagnosing atypical presentations.

A case is presented of a posterior mediastinal mass arising in a 57-year-old woman with severe compressive cervical symptoms and hyperthyroidism. Computed tomography showed intrathoracic thyroid tissue that displaced the trachea towards the front and the right and invaded the posterior mediastinum. Pathological examination showed features of a poorly differentiated (insular) thyroid carcinoma. To the best of our knowledge, this is the first reported case of a posterior mediastinal insular thyroid carcinoma with thyroid hyperfunction.

Introduction: The minimally invasive treatment of small renal masses with cryoablation has become increasingly widespread during the past 15 years. Studies with long-term follow-up are beginning to emerge, showing good oncological control, however, tumors with a central and endophytic location seem to possess an increased risk of treatment failure. Such tumors are likely to be subjected to a high volume of blood giving thermal protection to the cancerous cells. Arterial clamping during freezing might reduce this effect but at the same time subject the kidney to ischemia. The aim of this study was to evaluate the effect of renal artery clamping during cryoablation in a porcine survival model. Methods: Ten Danish Landrace pigs (approximately 40 kg) underwent bilateral laparoscopic cryoablation with clamping of the right renal artery during freezing. The cryoablation consisted of a standard double-freeze cycle of 10-minute freeze followed by 8 minutes of thaw. Arterial clamping subjected the right kidney to 2 cycles of ischemia (10 minutes) with perfusion in between. After surgery, the animals were housed for 14 days prior to computed tomography perfusions scans, radioisotope renography, and bilateral nephrectomy. Results: No perioperative or postoperative complications were experienced. Mean differential renal function was 44% (95% confidence interval: 42-46) in the clamped right kidney group and 56% (95% confidence interval: 54-58) in the nonclamped left kidney group, P < .05. The ±5% technical inaccuracy is not accounted for in the results. Mean maximum temperature between freeze cycles was 5.13°C (95% confidence interval: −0.1 to 10.3) in the clamped right kidney group and 22.7°C (95% confidence interval: −16.6 to 28.8) in the nonclamped left kidney group, P < .05. Mean cryolesion volume, estimated on computed tomography perfusion, was 12.4 mL (95% confidence interval: 10.35-14.4) in the clamped right kidney group and 6.85 mL (95% confidence interval: 5.57-8.14) in the nonclamped left kidney group, P < .05. Pathological examination shows a higher degree of vital cells in the intermediate zone of the cryolesions in the nonclamped left kidneys when compared with the clamped right kidneys. Conclusion: Arterial clamping increases cryolesion size by approximately 80%, and pathologic examinations suggest a decreased risk of vital cells in the intermediate zone. The clamped kidneys showed no sign of injury from the limited ischemic insult. This study was limited by being a nontumor model.

Ovarian Vein Thrombosis

A healthy 38-year-old woman, with no significant medical or surgical history, was referred to the gynaecology emergency department with acute low quadrant abdominal pain and nausea. On examination, painful palpation of right iliac fossa, abdominal guarding and positive Blumberg’s sign were noted. An abdominal-pelvic CT scan showed a hypodense tubular structure with peripheral enhancement to the right of the inferior vena cava, suggestive of thrombosis of the right ovarian vein. The only risk factor identified was the use of the combined contraceptive pill.

Aortocaval fistula (ACF) is a rare complication. Endovascular repair is an option for this fatal condition. However, endoleak and persistent fistula may occur and lead to technical failure. We performed endovascular repair for 3 cases of challenging ACF with hostile anatomy. Patient 1 was an 80-year-old man who complained of abdominal distension and lower limb edema for 15 days. He had renal and cardiac dysfunction. Computed tomography angiography (CTA) showed an ACF and extreme tortuosity of right iliac artery. The super-stiff guidewire could not pass the right iliac artery. We performed endovascular repair and an occluder was used to block the right external iliac artery. Postoperative CTA showed migration of the occluder, and we ligated the right external iliac artery. The patient survived for 5 years. Patient 2 was a 78-year-old man who complained of an acute abdominal pain for 30 hours. Computed tomography angiography showed great neck angulation (63.3°) and a huge aneurysm (9.9 cm in diameter). A type 1A endoleak occurred and an aortic cuff was deployed at the proximal seal zone. Meanwhile, a type 3 endoleak occurred because of the migration and detachment of the left iliac limb. Another stent-graft was deployed to connect the iliac limb. The patient was followed up for 1 year and remained in a good condition. Patient 3 was a 74-year-old man who experienced severe abdominal pain for 1 day. Computed tomography angiography showed great neck angulation (66°) and a huge aneurysm (10.1 cm in diameter). A type 1A endoleak occurred, and an aortic cuff was deployed at the proximal seal zone. The patient was followed up for 6 months. In conclusion, ACF is a rare but a fatal condition. Acute cases and chronic cases with instable hemodynamics need urgent diagnosis and surgical intervention. Endovascular repair is an efficacious alternative to the traditional open repair.
