Summary

Biliary hamartomas are rare liver lesions, often microscopic. This case highlights a rare instance where these benign hamartomas mimicked advanced gastric cancer liver metastases on imaging, emphasizing the need for accurate differential diagnosis.

Area of Science:

  • Hepatology
  • Radiology
  • Pathology

Background:

  • Gastric cancer commonly metastasizes to the liver.
  • Distinguishing benign liver lesions from malignant metastases is crucial for patient management.

Observation:

  • A 62-year-old female with advanced gastric cancer presented with multiple small, low-density liver nodules (<5 mm) on CT and a heterogeneous pattern on ultrasound.
  • Initial imaging suggested liver metastases from gastric cancer.

Findings:

  • Autopsy revealed the hepatic nodules were biliary hamartomas, a rare benign condition.
  • This case represents one of only nine reported instances of biliary hamartoma visualized via imaging.

Implications:

  • Advanced imaging techniques necessitate improved differentiation between biliary hamartomas and malignant hepatic neoplasms.
