Autoimmune pancreatitis type 2, an increasingly recognized etiology of pancreatitis in young patients without elevated IgG4. We report the case of a young woman admitted for acute pancreatitis, whose initial etiological record was negative. The evaluation of gravity by CT scan showed a slightly hipertrophic pancreas with the discovery of an aspect of ulcerative colitis "pancolitis". This association helped to guide the etiological diagnosis and treatment management. The patient was put on steroids with a rapidly favorable course, without recurrence and a 12-month follow-up.
