Primary tuberculous liver abscess: a case report and review of the literature.

A 48-year-old diabetic man was admitted to our hospital with abdominal pain in the right upper quadrant, weight loss, night sweats, fatigue, and anorexia. Ultrasonography, computed tomography, and magnetic resonance imaging of the abdomen revealed multiple hemangiomas and a hypodense mass lesion in the posterior segment of the right hepatic lobe. Histopathologic examination of the specimens obtained by ultrasonography-guided percutaneous needle biopsy revealed caseating granulomas with epithelioid histiocytes and giant cells. Systemic antituberculous therapy led to improvement of the lesion in the liver without necessitating surgery or percutaneous drainage. Tuberculosis should be considered in the differential diagnosis of hepatic mass lesions, especially in the presence of immune-compromised states. Ruling out tuberculosis may avoid delay in initiation of specific therapy in some cases. A greater awareness of this rare clinical entity may prevent needless surgical interventions.
