Isolated pancreatic tuberculosis (TB) is unusual, but obstructive jaundice secondary to pancreaticobiliary TB is extremely rare. The mechanisms by which tuberculosis causes bile duct obstruction are varied. Here, we describe a patient with pancreatic tuberculosis which mimicked pancreatic carcinoma with biliary obstruction clinically–radiologically.

A 60-year-old woman presented with a history of progressive jaundice, nausea, vomiting, and weight loss. There was no prior history of tuberculosis or family history of contact. Chest X-ray was normal. Abdominal ultrasound examination revealed an irregular hypoechoic lesion of 3 cm in the pancreatic head with dilation of entire bile duct system, mild dilated pancreatic duct, and distended gall bladder. Contrast-enhanced computed tomography (CT) scan showed a heterogeneous hypodense mass in the pancreatic head that cannot be a clear margin from pancreas and mild dilated pancreatic duct (Fig. 1). In addition, peripancreatic peripherally enhanc
