Extrapulmonary tuberculosis is an emerging problem [1-4]. Although the lymphatic system is the most frequently involved site, accounting for 31% of all cases of extrapulmonary tuberculosis , generalized tuberculous lymphadenitis (adenopathy involving two or more extra-inguinal sites) occurs almost exclusively in patients with cellular immunity deficit (primarily AIDS and AIDS-related conditions). Abdominal localization of tuberculosis is relatively uncommon and presents usually as peritonitis or enteritis involving the ileocecal or anorectal tract [5-7]. Except during the ourse of miliary tuberculosis, liver involvement with diffuse infiltration or localized abscess  is rare. The occurrence of lymphadenopathy at the hepatic hilum, associated with portal vein thrombosis and portal hypertension, is exceptional [8-11]. We describe a case of tuberculous lymphadenitis at the hepatic hilum, causing portal vein thrombosis and spreading through the lymphatic pathway to intrathoracic and cervical lymph nodes, in an immunocompetent patient. We also review the pertinent literature.
