Hepatic Lipoma: Radiological Imaging Findings
ABSTRACT
Hemangiomas and hepatic metastases are the leading reasons of echogenic masses on ultrasound (US) evaluation of the liver. Lipomas of the liver are extremely rare and have been sporadically reported in the literature during the last century. The present report describes a patient with hepatic lipoma together with liver metastases from gastric adenocarcinoma. A 54 years old woman was refered to our department because of abdominal pain. Patient has been operated for gastric adenocarcinoma 3 months ago she was evaluated with US, computed tomography (CT) and magnetic resonance imaging (MRI).The abdominal US revealed a 12 × 10 mm echogenic mass with smooth borders in 7th segment of the liver. CT scan showed a hypodense lesion in the same hepatic segment with fat dencity and no contrast involvement. MRI demonstrated the same lesion on T1 and T2 weighted images as hyperintence mass. The final radiographic diagnosis was he-patic lipoma. However, there was metastas in the liver of patient. Patient died 4 months later due to metas-tatic gastric adenocarcinoma. Hepatic lipoma should be kept in mind in echogenic masses on US evaluation of the liver.
