An 80-year-old woman had been diagnosed with IPMN and suffered from repeated acute pancreatitis since 2009. In 2011, penetration of IPMN into the stomach was found, and she was admitted to our hospital with fever and epigastric pain in May 2012.
During esophagogastroduodenoscopy it was found that the IPMN had penetrated into the stomach and also showed an increase in the tumor size. The patient’s symptoms were successfully treated via endoscopic drainage.
IPMN is partly characterized by expansive mucinous growth that may result in penetration into adjacent organs. The frequency of such penetration has been reported to be 7.9 to 15% of IPMN cases. Penetration occurs most often into the common bile duct, then the duodenum common bile duct, and finally the duodenum and stomach.
This unusual case of IPMN penetration into the stomach was associated with repeated acute pancreatitis.
