A liver biopsy can create a temporary pseudolesion that mimics cancer on CT scans. This finding in a hepatitis C patient resolved on its own, highlighting the importance of differential diagnosis.

Area of Science:

  • Hepatology
  • Radiology
  • Transplant Medicine

Background:

  • A 30-year-old female with chronic hepatitis C and renal insufficiency was evaluated for liver transplantation.
  • Percutaneous liver biopsy was performed as part of the transplant workup.

Observation:

  • Abdominal CT scans (pre- and post-contrast), CT-hepaticography, and CT-portography were conducted.
  • A 1 cm lesion mimicking hepatocellular carcinoma was identified.
  • The lesion was hypodense on CT-portography and enhanced on CT-hepaticography.

Findings:

  • The observed liver lesion was diagnosed as a post-biopsy pseudolesion.
  • This pseudolesion demonstrated characteristic enhancement patterns on specialized CT imaging.
  • The lesion showed spontaneous resolution over time.

Implications:

  • Recognizing post-biopsy pseudolesions is crucial for accurate differential diagnosis in liver imaging.
  • This case underscores the importance of correlating imaging findings with patient history, including recent procedures.
  • Avoidance of unnecessary interventions for transient, biopsy-induced changes can improve patient management.
