BELLIDO-CAPARO, Álvaro et al. Autoimmune pancreatitis type 1: a case report. Rev. gastroenterol. Perú [online]. 2017, vol.37, n.3, pp.254-257. ISSN 1022-5129.

Autoimmune pancreatitis type 1 (AIP) is the pancreatic manifestation of IgG4-related disease. The most frequent presentation of AIP is with obstructive jaundice. For definite diagnosis of type 1 Autoimmune pancreatitis international consensus diagnosis criteria (ICDC) for AIP are used. ICDC criteria include pancreatic parenchymal imaging, ductal imaging, serology, other organ involvement, histology, and response to steroid. We report a 52-years-old woman with rheumatoid arthritis without treatment presented with two months of abdominal pain in up-right quadrant with moderate intensity. She also presented jaundice, acholia, xerophtalmia, xerostomia, and a weight loss of 5 pounds. On examination jaundice, symmetrically enlarged submandibular glands, and epigastric pain was observed. On laboratory, a cholestasis pattern and conjugated bilirubin predominance was found. CT Abdominal, CMR revealed a dilated common bile duct with a diffuse pancreatic enlargement with delayed enhancement. Immunological studies show a IgG4 610 u/l and ANA 1/640. The patient responds to steroid clinically and in the laboratorial values. In conclusion, autoimmune pancreatitis type 1 should be suspected in case of an obstructive jaundice with a pancreatic inflammatory image, and complete ICDC criteria for a definite diagnosis
