title: Polyarteritis nodosa involving only the main renal arteries.
abstract: A unique case of accelerated hypertension and acute anuria in a 24-year-old man is presented. Clinically, the patient was found to have obstruction of both main renal arteries caused by extensive bilateral thrombosis. Microscopically, a healing panarteritis involving only the main renal arteries was found. This was associated with acute renal infarction and tubular atrophy in the left kidney. This appears to be an unusual variant of polyarteritis nodosa limited to both main renal arteries.
