Liver lipoma is a rare benign mesenchymal tumour without malignant degeneration. Lesions may be asymptomatic, nevertheless they may sometimes cause abdominal pain depending upon the size. Usually liver lipomas are an incidental finding during radiological examinations performed for other reasons, and there is no evidence of familiar genetic cluster or predisposing factors but it seems to have a strong association with impaired lipidic profile. In this report, we describe the case of a 72 year old female with a giant liver lipoma observed during an ultrasound examination. The clinical examination was completed with CT and MRI scans. Features of the lesion such as negative attenuation values on multiphasic CT examination and MRI signal drop-out on spectral presaturation with inversion recovery sequences, with no enhancement after administration of contrast medium, are suggestive for this kind of benign neoplasm. The purpose of this report is provide an anthological case of liver lipoma, helping to define the diagnostic features with imaging techniques.
肝脂肪瘤是一种罕见的良性间叶组织肿瘤,不会发生恶变。病变可能无症状,但有时会根据大小引起腹痛。通常肝脂肪瘤是在因其他原因进行的放射学检查中偶然发现的,没有家族遗传聚集或易感因素的证据,但似乎与脂质代谢异常密切相关。在本报告中,我们描述了一名72岁女性在超声检查中发现巨大肝脂肪瘤的病例。通过CT和MRI扫描完成了临床检查。该病变的特征,如多期CT检查时的负衰减值以及在频谱预饱和反转恢复序列上MRI信号缺失,注射造影剂后无强化,提示为这种良性肿瘤。本报告的目的是提供一例肝脂肪瘤的病例集萃,有助于通过影像学技术确定诊断特征。
