Abstract
A 64-year-old male patient was admitted because of fever, abdominal pain, and shock state. Ultrasonography and CT scanning of the abdomen revealed massive intra-abdominal hemorrhage. Palliative operation was performed and a fist-sized hematoma was found on the mesocolon transversum. Histopathologic examination revealed a rupture of the mesenteic artery and necrotizing angitis, accordingly he was diagnosed as periarteritis nodosa.
Periateritis nodosa presents with various clinical symptoms indeed, but a case presenting with intraabdominal hemorrhage like this case has nerver been reported in Japan.
