Hepatic steatosis is a frequent benign liver condition that can be idiopathic or secondary. The degree of fatty liver infiltration can be focal, diffuse or patchy. In this study, we present two patients with hepatic steatosis and multiple nodular liver lesions, due to fatty infiltration and fatty sparing respectively, mimicking a primary tumor or metastases ("pseudotumors"). Since the differential diagnosis of this kind of lesions can be difficult based on imaging alone, the knowledge of Contrast-Enhanced Ultrasound (CEUS) and Magnetic Resonance Imaging (MRI) findings may help radiologists to avoid an incorrect diagnosis of liver tumor, and unnecessary biopsies.
肝脂肪变性是一种常见的良性肝脏疾病，可为特发性或继发性。脂肪肝浸润程度可为局灶性、弥漫性或斑片状。在本研究中，我们报告了两名患有肝脂肪变性和多发肝脏结节性病变的患者，分别由于脂肪浸润和脂肪 sparing（此处可能有误，推测为脂肪 sparing，暂译为脂肪 sparing，即脂肪缺失），酷似原发性肿瘤或转移瘤（“假肿瘤”）。由于仅基于影像学对这类病变进行鉴别诊断可能存在困难，了解对比增强超声（CEUS）和磁共振成像（MRI）表现可能有助于放射科医生避免对肝脏肿瘤做出错误诊断以及进行不必要的活检。
