[Nontraumatic perirenal hematoma: a case report].

A patient with non-traumatic perirenal hematoma is reported. A 56- year-old woman visited our hospital with a complaint of left back pain. Computed tomographic scan showed left perirenal hematoma. Selective renal arteriogram demonstrated no apparent vascular abnormality but minor leakage of contrast medium was detected from the branch of the renal artery. The patient was treated with selective transcatheter arterial embolization. The patient has been followed up after the embolization without any complications. A total of 149 cases of non-traumatic perirenal hematoma were collected from the literature and discussed.
