Abdominal tuberculosis with pancreatic head involvement mimicking pancreatic malignancy in a young man: A case report

Figure 1 Contrast-enhanced computed tomography scan. A: An ill-defined mass with peripheral rim enhancement and internal low density in the head of the pancreas (left panel, black arrow); B: A coronal computed tomography scan revealing that the portal vein was partially encased by the lesion (right panel, white arrow).

Figure 2 Magnetic resonance imaging result. A: The portal vein is locally narrowed due to compression by the mass (left panel, black arrow); B: Magnetic resonance cholangiopancreatography revealing a stricture of the distal common bile duct (right panel, white arrow).

Figure 3 On laparotomy, tissue with caseous necrosis is identified above the pancreatic head (arrows).

Figure 4 Pathological examination showing epithelioid granulomatous inflammation with caseous necrosis, composed of epitheloid cells and occasional multinucleated giant cells (arrow). Hematoxylin and eosin staining; magnification, × 100.
