Abstract
A 45-year-old female presented with a chief complaint of epigastralgia. She had been treated at a regional hospital for pulmonary tuberculosis. On examination, she was found to have a mass located at the hepatic hilum on abdominal ultrasound. A computed tomography scan of the abdomen showed a pancreatic head cystic tumor. Positron emission tomography with 18F-fluorodeoxyglucose (FDG-PET) revealed a hot spot only in the pancreatic head. Under a presumptive diagnosis of malignancy, a laparotomy was performed. During the operation, a caseating necrotic mass and posterior pancreatic head lymph nodes were identified. Peripancreatic tuberculous lymphadenopathy was suspected. The diagnosis was confirmed on polymerase chain reaction (PCR) examination. Cases of peripancreatic tuberculous lymphadenopathy are rare. We reported a case of peripancreatic tuberculous lymphadenopathy mimicking pancreatic head cystic tumor that was difficult to diagnose preoperatively.
