title: Peripancreatic Tuberculous Lymphadenitis with Biliary Obstruction Diagnosed by Endoscopic Ultrasound-guided Fine-needle Aspiration Biopsy.
abstract: A 57-year-old man with a history of tuberculosis (TB) was found to have a pancreatic head mass, accompanied by stenosis of the common bile duct. Due to the inherent difficulty in differentiating pancreatic carcinoma from an inflammatory mass, endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB) was thus performed. The pathological findings confirmed granuloma with caseous necrosis, and the results of the QuantiFERON TB2G test were positive. Accordingly, the patient was diagnosed with peripancreatic TB and thereafter was successfully treated with anti-TB therapy. Based on the findings of this case, we conclude that EUS-FNAB is a useful modality for the diagnosis of pancreatic TB.
