title: Probable hepatic tuberculosis masquerading as Klatskin tumour in an immunocompetent patient.
abstract: A 55-year-old immunocompetent woman was presented with features of obstructive jaundice and a clinicoradiological picture suggestive of a hilar cholangiocarcinoma (Klatskin tumour). However, caseating granulomatous lesion associated with miliary nodules were revealed intraoperatively. The lesion responded to standard antituberculous therapy. This unusual presentation highlights the considerable diagnostic challenge in such case.
