| 4 | Autoimmune pancreatitis with atypical imaging findings that mimicked an endocrine tumor显示文摘Autoimmune pancreatitis(AIP) is a rare cause of recurrent acute pancreatitis or chronic pancreatitis in middleaged patients,and is characterised by a marked infiltration of lymphocytes and plasma cells in pancreatic tissue.Diagnosis of focal forms can be diff icult as AIP may mimic pancreatic adenocarcinoma.Pediatric cases of AIP are exceptional.We report the case of a 15-yearold girl who had a focal AIP and associated cholangitis,with a very unusual vascularized mass that mimicked a pancreatic endocrine tumor.The diagnosis was obtained by a pancreatic biopsy,thus avoiding surgical resection,and all the clinical,biological and radiological abnormalities resolved after steroid therapy with 6 mo of follow-up. | Cindy Neuzillet Céline Lepère Mostafa El Hajjam Laurent Palazzo Monique Fabre Hajer Turki Pascal Hammel Philippe Rougier Emmanuel Mitry | 2010 | World Journal of Gastroenterology2010，16，23： | 0 |
