Anastomosing hemangioma (AH) is rare and a newly recognized variant of capillary hemangioma that is mostly found in the genitourinary tract. Additionally, AH is sometimes difficult to diagnose without pathological specimens. It is difficult to diagnose preoperatively due to the lack of specific clinical and radiologic appearance. The present report describes the imaging features from a radiological perspective and outlines the clinicopathologic features and treatment options. A 67-year-old woman was referred to Dokkyo Medical University Saitama Medical Center (Koshigaya, Japan) for a retroperitoneal tumor that was identified at a medical checkup 4 years prior. The patient had no symptoms, no abnormal physical signs and no past medical or specific family history. Routine blood tests were all within the normal ranges. A nonenhanced CT scan showed a circular, homogenous, well-circumscribed retroperitoneal tumor that was ~32x23 mm in size, between the abdominal aorta and the inferior vena cava, and just below the left renal vein. On a contrast-enhanced multidetector CT scan, the tumor showed heterogeneous septal enhancement in the arterial phase and persistent enhancement in the portal phase. The tumor was diagnosed as a benign neurogenic tumor or a retroperitoneal cavernous hemangioma at the time, and the patient was intended to be followed up at the outpatient clinic. However, it gradually increased to a maximum diameter of 35 mm over 4 years. Finally, it was completely resected by open laparotomy and pathologically diagnosed as AH. Retroperitoneal hemangioma is extremely rare in adulthood and has been confirmed in only 1-3% of all retroperitoneal tumors. To the best of our knowledge, only 6 cases of para-aortic AH have been reported. The incidence of this variant is very low. However, AH may be included in the differential diagnosis when a slowly progressing heterogeneous mass appears in the para-aortic region that exhibits a CT-enhanced pattern similar to a typical cavernous hemangioma.

When obstructive lesions from the uterus or ovaries are suspected, patients with hydronephrosis are usually referred to a gynecologist. Here, a case of suspected endometriosis-related hydroureteronephrosis is reported. A 43-year-old woman with hydronephrosis was found to have a left distal periureteral tumor on the computerized tomography scan. Before the operation, the hydroureteronephrosis was suspected caused by the obstruction of ureter, related with ureteral endometriosis; however, the postoperative pathology revealed the diagnosis of retroperitoneal well-differentiated liposarcoma. When female patients have hydronephrosis, gynecologic causes should be considered. Both benign and malignant causes are needed to include when making differential diagnosis. Therefore, robot-assisted surgery is a feasible option because of its lower morbidity rate and more precise dissection of soft tissue than laparotomy in both benign and malignant retroperitoneal tumors.

“…A robotic approach has its advantage as well, as it can share similar peri-operative complications as standard laparoscopy, while enhancing the ability to remove more surgically complex disease [13]. Robotic surgery has been well-described as an effective technique for procedures such as retroperitoneal lymph node dissections (RPLND) [14]; however, despite frequent utilization of robots in urology, robot-assisted laparoscopic excision of primary retroperitoneal tumors is not well-documented, with fewer than 45 cases reported in the literature [15]. Furthermore, primary retroperitoneal teratomas make up only 1-11% of this larger group of retroperitoneal tumors [1], indicating that robotic surgery is even less frequently used for these tumors.…”

Mature teratomas are unique and generally benign neoplasms. They are derived from embryonic tissues and typically located within the gonadal region. Primary retroperitoneal teratomas are uncommon in adults and often challenging to treat, given their location and size. Here, we offer a rare case of a large primary retroperitoneal mature cystic teratoma, detected on abdominal ultrasound during the work-up of abdominal bloating and nausea and treated with robot-assisted laparoscopic excision in a 58-year-old male. In this report, we sought to describe the evaluation, treatment, and follow-up of this condition, as well as review the associated literature.
