Spontaneous perirenal hematoma in a lupic patient on haemodialysis treatment and with renal cysts

Abstract

The spontaneous perirenal hemorrhage usually presents as sudden pain in the side ipsilateral, no history of trauma. Acquired cystic kidney disease is a common finding in chronic hemodialysis patients. However, spontaneous bleeding from the rupture of the cyst is a rare clinical entity. We describe the case of a female patient, 45 years old, with controlled hypertension for 8 years, chronic renal failure for 15 years and lupus nephritis 2 years ago, undergoing hemodialysis three times a week since 2006, and who presented concurrently acquired cystic kidney disease. She was admitted to the emergency department complaining of sudden onset of pain in the thoraco-abdominal left. Perirenal hematoma was diagnosed by ultrasound and computed tomography of the abdomen. The patient underwent embolization of left renal artery, with good evolution.
