Inferior epigastric artery pseudoaneurysm secondary to port placement during a robot-assisted laparoscopic radical cystectomy.

Pseudoaneurysm occurs when the artery wall is damaged and the blood is contained by the surrounding tissues with the eventual formation of a fibrous sac communicating with the artery. We report a case of a 74-year-old man with inferior epigastric artery (IEA) pseudoaneurysm secondary to an 8-mm port placement during a robot-assisted laparoscopic radical cystectomy with ureteroileocutaneostomy. The pseudoaneurysm was initially diagnosed by contrast-enhanced ultrasound (CEUS); subsequently, a computed tomography (CT) scan and an angiography test were performed. The pseudoaneurysm was then treated successfully with embolization of the inferior epigastric artery. Awareness of this rare complication is of clinical importance to avoid excessive morbidity of affected individuals.

A rare case of renal tumor in children: clear cell sarcoma.

Clear cell sarcoma of the kidney is an uncommon renal neopla sm of childhood. It represents about 4% of childhood malignant neoplasms and is generally more common in children under 5 years of age. In the present article, we describe the case of a 12-year-old male patient who came to our observation with left renal mass and with a clinical-laboratory picture indicative of inflammatory pathology.
