Imaging techniques accurately diagnose common benign liver lesions like hemangioma and FNH. For rarer conditions, clinical data aids interpretation, but biopsy may still be needed for definitive diagnosis.

Area of Science:

  • Radiology
  • Hepatology
  • Medical Imaging

Background:

  • Benign focal liver lesions present a diagnostic challenge.
  • Accurate characterization is crucial for appropriate patient management.
  • Current imaging modalities offer varying degrees of diagnostic certainty.

Purpose of the Study:

  • To review the diagnostic capabilities of current imaging techniques for benign focal liver lesions.
  • To highlight the role of clinical data in interpreting imaging studies for uncommon lesions.
  • To determine when tissue biopsy remains necessary for diagnosis.

Main Methods:

  • Review of cross-sectional imaging features of common and uncommon benign liver lesions.
  • Integration of clinical data with imaging findings for lesion characterization.

  • Discussion of the limitations of imaging in diagnosing specific entities.

    • Main Results:

    • Common benign liver lesions (hemangioma, bile duct cyst, FNH) show characteristic imaging features.
    • Atypical variants and uncommon lesions (HCA, angiomyelioma, infantile hemangioendothelioma, mesenchymal hamartoma) often require clinical data integration.
    • Some lesions, like hepatic adenomatosis, may have non-specific imaging findings necessitating biopsy.

    Conclusions:

    • Current imaging techniques are effective for diagnosing most common benign liver lesions.
    • Clinical correlation is valuable for interpreting imaging of rarer or atypical liver lesions.
    • Tissue biopsy remains essential for definitive diagnosis in cases with non-specific imaging findings.
