Pancreatic pseudocyst: unusual presentation of polyarteritis nodosa

Eventhough pancreatic involvement in case of polyarteritis nodosa is uncomm on, it reveals unfrequently the disease. Furthermore, the occurence of panc reatic pseudocyst in case of polyarteritis nodosa is rare. One case of intr apancreatic pseudocyst complicating chronic pancreatic during polyarteritis nodosa is reported. CT scan showed non specific intrapancreatic cystic les ion for which the diagnosis of mucinous cystic tumor of the pancreas was co nsidered. After surgical resection, histopathologic analysis led to the dia gnosis of intrapancreatic pseudocyst secondary to polyarteritis nodosa.
