title: Clinics in diagnostic imaging (4). Renal angiomyolipoma with spontaneous perinephric haemorrhage.
abstract: A 69-year-old Chinese woman presented with acute right-sided abdominal pain. Intravenous urogram and ultrasound demonstrated a fatty lower renal pole mass with a perinephric collection. The diagnosis of renal angiomyolipoma was confirmed by computerised tomography. The perinephric haemorrhage resolved with conservative treatment. The classification, clinical features and management of this entity is discussed. The role of imaging in diagnosis and follow-up of renal angiomyolipoma is emphasised.
