Hepatic and splenic tuberculosis refers to tuberculosis affecting the liver and the spleen. It generally occurs due to hematogenous spread from the primary site of infection, commonly from pulmonary tuberculosis.
Two types of lesions are known:
There may be small hypoechoic nodules (miliary type) or larger hypoechoic mass-like areas 2,3.
micronodular (miliary) type 1:
small low attenuation areas with central enhancement (acute stage)
calcification (chronic stage)
macronodular type 1,4:
single or multiple tumor-like masses
rarely >3 cm in diameter
T1: lesions are usually isointense when compared to the background parenchyma
T2: mixed signal with hyperintense areas
T1 C+ (Gd): variable, reflecting the phases of the disease
