Isolated Pyogenic Pancreatic Abscess Mimicking a Neoplasm

Vui Heng Chong

Abstract

Context Pancreatic abscesses are uncommon and usually occur in the setting of pancreatitis. Isolated pyogenic pancreatic abscesses without any precipitating events are extremely rare. Case report A 72-year-old man with a two month history of non-specific abdominal discomfort, distension, anorexia and weight loss was admitted for further evaluation. A computer tomography scan showed a lesion of the pancreatic head suspicious for a malignancy. Unexpectedly, Klebsialla pneumoniae was isolated from the aspiration biopsy without any evidence of malignancy. A repeat CT scan four months later showed resolution of the abscess after a six week course of antibiotic. Conclusion Our case highlights a rare case of isolated pyogenic pancreatic abscess secondary to Klebsialla pneumoniae mimicking an underlying pancreatic malignancy. Infective causes should be considered to avoid any unnecessary major surgery.
