- Abstract: Abdominal tuberculous lymphadenopathy is a rare condition that can cause obstructive jaundice. The feature of tuberculosis lymphadenopathy may resemble those of cancer, metastasis, or lymphoma on computed tomography (CT) or magnetic resonance imaging; therefore, physicians must perform appropriate examinations, make correct diagnoses, and conduct suitable treatment. Herein, we report a case of obstructive jaundice caused by tuberculous lymphadenopathy. The patient was 27 years old, with an initial serum total bilirubin level of 6.76 mg/dL and a direct bilirubin level of 5.64 mg/dL. Aspartate transaminase and alanine transaminase levels were 466 and 801 IU/L, respectively. Abdominal CT revealed a mass-like effect and extraluminal compression accompanying bile duct obstruction. An abrupt bile duct stricture was observed on endoscopic retrograde cholangiopancreatography; thus, a biopsy was performed. However, the specimen which was taken by endoscopic retrograde cholangiopancreatography was confirmed to constitute superficially biopsied bile duct mucosa and benign-looking epithelial cell stripes. Positron emission tomography-CT showed a hypermetabolic lesion in the hepato-duodenal ligament with small lymph nodes in the aortocaval and retrocaval spaces. Additionally, it showed hypermetabolism of the neck lymph node at level II. The neck lymph node was biopsied. Granulomatous inflammation was observed and nested tuberculosis polymerase chain reaction was positive. The patient was treated with anti-tuberculosis medications and underwent endoscopic retrograde biliary drainage without surgery.
