Hepatic hamartoma

Hepatic hamartoma


These tumours are primarily non – neoplastic malformations containing a variety of tissue types of mesenchymal origin. They are not locally destructive although may produce pressure effects.


They are rare but will appear in the liver as cystic spaces which may be septated and very large.

Differential Diagnosis

Other cystic structures in the liver including choledochal cyst which is located near the portal tract and may be associated with dilated bile ducts. Hepatic haemangioma are likely to contain obvious blood flow. Hepatic cyst is usually smaller.

Sonographic Features

Large hypoechoic mass within the substance of the liver

These masses may replace the liver entirely

Associated Syndromes

  • Tuberous sclerosis
