title: [Idiopathic retroperitoneal hematoma. Apropos of a case].
abstract: A 10 year-old girl presented with a progressive left ureteral colic with abdominal tenderness. Ultrasonography revealed pyelocalyceal dilatation and an intravenous pyelogram showed lateral deviation of the left ureter. Computed tomography confirmed retroperitoneal mass distinct from psoas. Laparotomy revealed an encapsulated retroperitoneal hematoma. No particular aetiology was found and the patient's health remained stable after treatment.
