Contrast-enhanced CT (a) and T1 weighted contrast-enhanced MR images (b) show a small abscess formation with rim-like enhancement in the anterior subcapsular region of the liver. Diffusion-weighted images (DWI) (c) and apparent diffusion coefficient (ADC) map (d) reveal diffusion restriction consistent with an abscess

Hepatic and splenic tuberculosis refers to tuberculosis affecting the liver and the spleen. It generally occurs due to haematogenous spread from the primary site of infection, commonly from pulmonary tuberculosis.

Pathology

Two types of lesions are known:

micronodular (common)
macronodular (rare)

Radiographic features

Ultrasound

Nonspecific features are usually seen, including hepatosplenomegaly and abscesses .

There may be small hypoechoic nodules (miliary type) or larger hypoechoic mass-like areas .

CT

micronodular (miliary) type
- multiple
- small low attenuation areas with central enhancement (acute stage)
- calcification (chronic stage)
macronodular type
- single or large tumor-like mass
- diffuse hepatosplenomegaly
