Extrarenal angiomyolipomas of the perinephric space in tuberose sclerosis

Retroperitoneal extrarenal angiomyolipomas: an evidence-based approach to a rare clinical entity

Extrarenal angiomyolipomas (ERAMLs) are rare tumors that present as incidentalomas upon imaging for other conditions. Retroperitoneal ERAMLs present a unique challenge from a diagnostic and treatment standpoint as they can mimic other benign and malignant retroperitoneal tumors. We present a case of a 39-year-old female with a 19.3 cm × 13.5 cm × 10.7 cm left extrarenal retroperitoneal mass. Histopathologic examination and HMB-45 staining revealed the mass to be a retroperitoneal ERAML. Our case report provides a comprehensive literature review and an evidence-based algorithm for taking care of patients with ERAMLs.

Giant bleeding renal angiomyolipoma: diagnosis and management

A case of a giant bleeding renal angiomyolipoma is presented. The patient was a 40-year-old Egyptian male with no clinical or radiological evidence of tuberous sclerosis. The radiological features and management, including the role of angiography are briefly discussed and the medical reviews on this subject are briefly considered.
