Hepatic and splenic tuberculosis

Last revised by Dr Ammar Ashraf on 02 Aug 2021

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:

  • micronodular (common)
  • macronodular (rare)

Nonspecific features are usually seen, including hepatosplenomegaly and abscesses 3.

There may be small hypoechoic nodules (miliary type) or larger hypoechoic mass-like areas 2,3.

  • micronodular (miliary) type 3
    • multiple
    • small low attenuation areas with central enhancement (acute stage)
    • calcification (chronic stage)
  • macronodular type 3
    • single or large tumor-like mass
    • diffuse hepatosplenomegaly
  • T1: lesions usually isointense when compared to the background parenchyma
  • T2: mixed signal with hyperintense areas
  • C+ (Gd):  variable, reflecting the phases of the disease
