[Intraperitoneal hemorrhage after labor as manifestation of renal angiomyolipoma]
We report a case of renal angiomyolipoma in a patient who, following normal delivery, presented with abdominal pain and acute abdomen with severe hemodynamic compromise that led to hypovolemic shock. Following diagnosis by emergency exploratory laparotomy, a left nephrectomy was performed. We underscore the difficulty involved in the diagnosis of acute abdomen from hemoperitoneum resulting from a ruptured angiomyolipoma, and highlight the rarity of this condition. Our patient was submitted to radical surgery because of vessel (hilum) invasion. The tumor was benign and no complications were observed. Patient work up eight years postoperatively revealed no local or systemic evidence of disease.

The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...
