A case of alcoholic pancreatitis with a pseudocyst associated with pancreatic cancer-like findings

Abstract

A 60-year-old man who was diagnosed as having type 0-IIc gastric cancer was admitted to our hospital because of epigastric pain. Abdominal CT revealed acute pancreatitis with a pseudocyst. Abdominal MRI, CT and endoscopic ultrasoundgraphy showed an unusual mass lesion in the pancreas head. Endoscopic retrograde cholangiopancreatography and cytologic examination didnt allow the diagnosis of adenocarcinoma. However, we could not rule out the presence of a malignant lesion, so pancreaticduodenectomy was performed. The histological diagnosis was pancreatitis with fibrotic tissues and there was no evidence of malignancy. A novel diagnostic modality may be necessary for improving the accuracy of diagnosis in such cases.
