Magnetic resonance imaging (MRI) revealed key features in hepatocellular carcinoma (HCC) patients. Fatty degeneration, capsule, mosaic pattern, daughter nodules, and tumor thrombi were observed in a significant portion of the thirty participants.

Area of Science:

  • Radiology
  • Oncology
  • Hepatology

Background:

  • Hepatocellular carcinoma (HCC) is a primary liver cancer with significant global impact.
  • Accurate diagnostic imaging is crucial for HCC staging and treatment planning.

Purpose of the Study:

  • To evaluate the prevalence of distinctive Magnetic Resonance Imaging (MRI) findings in patients diagnosed with hepatocellular carcinoma (HCC).

Main Methods:

  • Retrospective analysis of MRI scans from thirty (30) patients with confirmed hepatocellular carcinoma.
  • Assessment for specific HCC imaging characteristics: fatty degeneration, capsule, mosaic pattern, daughter nodules, and tumor thrombi in major veins.

Main Results:

  • Fatty degeneration was observed in 20% (6/30) of cases.

  • A capsule was present in 43% (13/30) of cases.
  • Mosaic pattern (3%), daughter nodules (33% or 10/30), and tumor thrombi in major veins (30% or 9/30) were also noted.

    • Conclusions:

    • MRI demonstrates characteristic findings in hepatocellular carcinoma, aiding in diagnosis and characterization.
    • The presence of a capsule and daughter nodules are relatively common findings in HCC on MRI.
    • Tumor thrombi in major veins, a significant prognostic indicator, were identified in 30% of the studied HCC cohort.
