Abstract: Isolated heaptic tuberculous granuloma with no coexistent tuberculosis elsewhere in the body is extremely rare. We report a case of pathologically proven tuberculous granuloma in the liver followed with both IV bolus and portal CT scans. The lesion on preenhanced CT scan showed undefinable isodensity. After IV bolus injection, it showed poor enhancement with central low-density and surrounding hyperdenity due to compensatory hypervascularity of the left lobe of liver in early phase. It showed peripheral rim enhancement in late phase and in delayed phase showed relatively homogeneous but slightly decreased contract enhancement. On portal CT scan, it showed a hypodense portal defect similar to other hepatic mass lesions. During follow-up studies, it was a slowly growing mass which was more easily detectable by prtal CT scans than bolus CT scans.
