The computed tomographic appearances of benign hepatic hamartoma.

The case of a 32-year-old female with asymptomatic hepatomegaly due to a large cystic liver mass is described. Pathological examination after total excision revealed a benign hepatic hamartoma. Benign hepatic hamartoma is a rare cause of a cystic liver mass, usually occurring below the age of 5 years. The computed tomography findings included 'daughter cysts' and it is emphasised that these must not be regarded as pathognomonic of hydatid disease.
