title: Spontaneous perirenal hematoma: a complication of polyarteritis nodosa.
abstract: Polyarteritis nodosa is a rare cause of perirenal hematoma owing to rupture of 1 of the aneurysms. Eleven cases have been reported previously in the English literature, including 5 with a preoperative angiographic diagnosis. Our case, which was diagnosed angiographically before a successful conservative operation, is the first report of a patient who survived 3 years. The pathology is discussed.
