İnsidental hepatik lipomda radyolojik bulgular

Year 2009, Volume: 24 Issue: 4, 181 - 184, 01.05.2009

Abstract

A 58-year-old man was admitted with nonspecific abdominal pain. Physical examination and laboratory findings were in normal limits. Well-demarcated homogeneous hyperechoic lesion of the liver was delineated on abdominal ultrasonography (US) imaging. Fat content was clearly demonstrated on computerized tomography (CT) and magnetic resonance imaging (MRI) that were performed to clarify the nature of the lesion, and hepatic lipoma was diagnosed based on radiological findings. Hepatic lipoma is an extremely rare benign tumor of the liver. It is usually an asymptomatic lesion diagnosed incidentally. On US, it is seen as a well-circumscribed, round- or ovalshaped, homogeneously hyperechoic, peripherally located lesion, which is not distinguishable from other hyperechoic lesions like hemangioma or metastasis. Doppler US does not provide additional information. Differential diagnosis is especially important in oncology patients; thus, further imaging techniques should be performed. CT and MRI are helpful to identify its pure fat content, preventing biopsy requirement. Radiological findings including US, CT and MRI in a 58-yearold man admitted for abdominal sonography with incidental hepatic lipoma are presented in this paper.

Radiological findings of incidental hepatic lipoma

Abstract

Elli sekiz yaşında erkek hasta nonspesifik karın ağrısı nedeniyle hastanemize başvurdu. Fiziksel inceleme ve laboratuvar bulgularında özellik yoktu. Karın ultrasonografisi (USG) ile değerlendirme sırasında karaciğerde düzgün sınırlı homojen hiperekojen lezyon saptandı. Lezyonun natürünün belirlenmesi için yapılan bilgisayarlı tomografi (BT) ve manyetik rezonans görüntüleme (MRG) incelemelerinde lezyonun yağ içeriği net olarak gösterildi ve radyolojik olarak hepatik lipom tanısı konuldu. Hepatik lipom karaciğerin son derece nadir görülen benign tümörüdür. Genellikle asemptomatik olup tanı rastlantısal olarak konulur. USG incelemede yuvarlak veya oval, hiperekoik görünümde olup periferik yerleşimdedir. USG bulguları ile diğer sıkça rastlanan hiperekojen lezyonlardan hemanjiom veya metastazdan ayırt edilemez. Doppler USG ayırıcı tanıda ek bilgi vermez. Özellikle onkoloji hastalarında ayırıcı tanı önem arz ettiğinden ileri radyolojik değerlendirme gerekir. BT ve MRG ile lezyonun tamamen yağ içeriğinin gösterilmesi tanı koydurucudur, biyopsi gerekliliğini ortadan kaldırır. Bu yazıda, radyolojik olarak tanısı konan insidental saptanan hepatik lipomun USG, BT ve MRG içeren radyolojik bulguları sunulmaktadır.
