A CASE OF SEROUS CYSTADENOMA OF THE PANCREAS ACCOMPANIED WITH FOCAL CHRONIC PANCREATITIS

A 67-year-old woman was pointed out having a lesions in the pancreas during the treatment for tuberculosis of the lung with INH/RF/EB. Abdominal ultrasonography showed a low echoic lesion, sized 20×17mm, in the body of the pancreas, in which high echoic spot without acoustic shadow was seen. The lesion was recognized to be a low density area in CT. In MRI, it was low intensity area in T1, and high intensity area in T2 weighted image. In ERP, the main pancreatic duct was slightly pressed. Abdominal angiography revealed a slightly stained lesion. Cystic pancreatic disease or localized pan-creatitis was suspected. On laparotomy, the body of the pancreas was localized hard and adhered to the surrounding tissue. Resection of the body and tail of the pancreas with spleen was performed. Path-ologically, most of the lesion was composed of hyalinized, organized, and granulated serous cystadenoma. Localized pancreatitis was existed in contact with it. We supposed that localized pancreatitis was caused by the existence of serous cystadenoma, and then the inflammation spread to the adenoma.
