The operative treatment of chronic contained rupture of a saccular abdominal aortic aneurysm (AAA) with retroperitoneal haematoma is reported. A 62-year-old man presented with a painless abdominal mass and intermittent claudication. He had an episode of severe abdominal pain about 2 years before admission. A giant retroperitoneal neoplasm was initially suspected, based on computed tomography. However, magnetic resonance imaging, angiography and colour Doppler sonography demonstrated chronic contained rupture of an AAA. A punched-out oval defect (width 3.5 cm x length 4.5 cm) that was thought to connect the thrombosed aneurysm to an organized retroperitoneal haematoma was discovered in the posterior wall of the bifurcation of the aorta at laparotomy. An infrarenal aortobiexternal iliac Y-graft with bypass to the left femoral artery was placed without removing the aneurysm or haematoma. Recovery was uneventful. The retroperitoneal haematoma appeared smaller on computed tomography about 1 year after operation. This case fulfilled the criteria for chronic contained rupture of an AAA proposed by Jones and associates.

The Authors report a rare case of retroperitoneal leiomyosarcoma in a 80 years woman with respiratory symptoms and right abdominal pain. A large neoplasm occupied the right abdomen, looking asymmetric. Upper abdominal CT showed a retroperitoneal neoplasm close to right kidney, liver, aponeurosis of right oblique muscles, producing a left-side dislocation of the intraabdominal organs. A surgical "en bloc" resection of the neoplasm was performed; neoplasm was plurilobed and capsulated. The histologic examination confirmed the diagnosis of leiomyosarcoma. The best treatment of these neoplasms is surgery, that in the last years has drawn advantage from more sensible and specific diagnostic procedures, which show a more radical surgical option. Though metastases are occasional, local recurrences can be taken into consideration and, after a careful tumoral re-staging, they can be resected once more. Therefore, a careful follow-up is necessary on the basis of neoplastic grading, extension and involvement of the closer structures.

Paragangliomas are extra-adrenal tumors of the autonomic nervous system and may be found within the skull base, neck, chest, and abdomen. When presenting within the abdominal cavity, they may arise as a primary retroperitoneal neoplasm and can mimic vascular malformations or other conditions related to specific retroperitoneal organs such as the pancreas, kidneys, or adrenals. Retroperitoneal paragangliomas are mostly benign with good prognosis; however, they can present with abdominal pain, palpable mass, or hypertensive episodes. Patients should be initially evaluated with catecholamine levels, followed by computed tomography or magnetic resonance imaging to locate the primary lesion. Surgical excision remains the mainstay of treatment, although advanced disease and proximity to vital organs can make excision difficult or impossible. This case report describes a patient who initially underwent work up for a suspected pancreatic head mass which was discovered to be a retroperitoneal paraganglioma by frozen section.
