A case of tuberculosis presented by obstructive jaundice tuberculosis-related mechanical icterus.

Obstructive jaundice caused by tuberculosis lymphadenitis is a rare condition. It can mimic clinical and radiological findings of hepatobiliary malignancies. The authors report a 24-year-old male patient who presented with abdominal pain, fever and jaundice for the last two weeks. It was found that cholestasis enzymes were increased by 2-3 fold and direct bilirubin was 6.13 mg/dL. Imaging studies revealed conglomerated lymph nodes with some cavitary lesions and dilated intrahepatic biliary canal secondary to compression by the lymph nodes. Tuberculosis was found to be positive in the polymerase chain reaction analysis of the aspirate that was obtained in the guidance of imaging studies. M. tuberculosis complex was isolated from mycobacterial culture. Anti-tuberculosis treatment was initiated. Clinical, laboratory and radiological findings completely resolved by medical therapy alone. Tuberculosis lymphadenitis should be kept in mind in cases presenting with obstructive jaundice in endemic areas and interventional diagnostic techniques should be preferred in eligible patients.
