[Primary hepatic tuberculosis in an immunocompetent patient: a case report]

Tuberculosis (TB) is a common infectious disease that most often affects the lungs, but it can also affect any other organ with a wide range of clinical manifestations. There are three forms of hepatic involvement: diffuse hepatic tuberculosis combined with pulmonary tuberculosis; diffuse hepatic tuberculosis without pulmonary involvement; and nodular or focal/local hepatic tuberculosis, which is a very rare form and presents a diagnostic challenge. We here report the case of a young Moroccan man presenting with biliary colic that had been evolving for a month, associated with a forme fruste of tuberculous impregnation. CT scan and magnetic resonance imaging (MRI) of the liver showed nodular hepatic lesions. The diagnosis of focal hepatic tuberculosis was confirmed based on anatomopathological examination of biopsies obtained during laparoscopy. The patient received antitubercular treatment with good clinical-biological outcome.
