The paratesticular region is a relatively small anatomical compartment containing a disproportionately large number of anatomic structures. In addition to the testicular collecting system there are mesothelial and mesenchymal components representing extensions of the abdominal cavity and retroperitoneum. The epithelial, mesothelial, and connective tissue elements give rise to a wide variety of ...

Pancreatic and duodenal injuries are not common and their detection can be challenging both preoperatively and during explorative laparotomy. Their protected location in the retroperitoneum can give subtle symptoms and signs in isolated injuries leading to delayed diagnosis and management. The purpose of this review is to outline the main characteristics of treating these injuries with emphasis...

Primary retroperitoneal mucinous neoplasms are extremely rare tumors. Less than sixty cases have been reported in international literature until date, with striking female predominance. We report a case of primary mucinous cystadenocarcinoma of the retroperitoneum in a 51-year-old male presenting with nonspecific abdominal complaints. This case is being highlighted for its rare occurrence in a ...

An unusual case of abdominal aortic aneurysm with simultaneous rupture in the retroperitoneum and in the inferior vena cava is reported. The patient presented with clinical signs of hemorrhagic shock, peripheral venous congestion and acute renal failure. An urgent contrast-enhanced computed tomography was performed , leading to an accurate diagnosis , and straight to surgery.

BACKGROUND Recent studies have demonstrated that pathological analysis of retroperitoneal residual masses of patients with testicular germ cell tumors revealed findings of necrotic debris or fibrosis in up to 50% of patients. We aimed at pursuing a clinical and pathological review of patients undergoing post chemotherapy retroperitoneal lymph node dissection (PC-RPLND) in order to identify vari...

  Abdominal cystic lymphangioma is a rare benign neoplasm. Less than 1% of lymphangiomas is in the retroperitoneum. Lymphangioma is mostly asymptomatic. Chronic symptoms were reported in retroperitoneal type more than others. Acute symptoms due to complications like infection, cyst rupture or hemorrhage may occur. We report an 18-years-old girl with low back pain from 6 months ago with huge pel...
