This autopsy study examined liver changes in 150 tuberculosis cases. Histopathology revealed granulomas in 42% of patients, with secondary liver involvement being most common, and significant fibrosis in 7.3%.

Area of Science:

  • Pathology
  • Hepatology
  • Infectious Diseases

Background:

  • Tuberculosis (TB) can affect multiple organs, including the liver.
  • Understanding the spectrum of hepatic histopathological changes in TB is crucial for diagnosis and management.

Purpose of the Study:

  • To investigate the range of histopathological alterations in the liver of patients with tuberculosis.
  • To correlate liver findings with the type and extent of tuberculosis.

Main Methods:

  • An autopsy-based study of 150 adult tuberculosis cases over three years.
  • Detailed gross examination of the liver and extrahepatic biliary tree.
  • Routine processing and histopathological analysis of liver sections.

Main Results:

  • The majority of liver involvement was secondary to pulmonary or extrapulmonary tuberculosis.
  • Histopathological findings included epithelioid cell granulomas (42%), fatty changes (32.6%), inflammation (40%), sinusoidal congestion (32%), and fibrosis (16%).
  • Significant fibrosis (Stage III-IV) was observed in 7.3% of cases, with a higher incidence of fatty changes and inflammation in granuloma-positive cases.

Conclusions:

  • Liver involvement in tuberculosis is predominantly secondary.
  • Epithelioid cell granulomas are a key histopathological finding, though non-specific changes are also prevalent.
  • While fibrosis can occur, tuberculosis's role as a consistent cause of significant fibrosis requires further investigation.
