Idiopathic fibrosing pancreatitis: a cause of obstructive jaundice in childhood

Idiopathic fibrosing pancreatitis is a chronic process of unknown etiology characterized by extensive infiltration of the pancreatic parenchyma by fibrous tissue [1, 2]. This disease process is uncommon in the pediatric patient and is consequently rarely considered in the differential diagnosis of abdominal pain and jaundice in the child. The sonographic demonstration of a dilated biliary tree and common bile duct compressed by an enlarged pancreas may be the first suggestion of this entity. Two patients with idiopathic fibrosing pancreatitis and obstructive jaundice are reported with a review of the clinical, radiographic, and pathologic findings.
