Hepatic pseudolipoma is a relatively rare benign tumor of the liver in primary hepatic lesions and is characterized by focal fat around the liver capsule. It typically affects older adult men. In this case report, we discuss the case of a 71-year-old male who presented to our hospital with rectal adenocarcinoma. A pseudolipoma was incidentally detected on a preoperative computed tomography scan of the abdomen. We performed contrast-enhanced ultrasound to clarify the nature of this tumor. To the best of our knowledge, there have not been any documented reports on contrast-enhanced ultrasound findings of hepatic pseudolipoma.
Hepatic pseudolipoma appears on contrast-enhanced ultrasound as slightly hyperechoic nodule with poorly defined borders and regular morphology.
On the basis of the patient's clinical symptoms, test results, and imaging manifestations, the lesion was considered a pseudolipoma, not a liver metastasis from rectal cancer. Pseudolipoma usually does not need treatment.
The current report will help enhance the current knowledge regarding identifying hepatic pseudolipoma by contrast-enhanced ultrasound imaging and review the related literature.
肝假性脂肪瘤是原发性肝脏病变中一种相对罕见的肝脏良性肿瘤，其特征为肝包膜周围的局灶性脂肪。它通常影响老年男性。在本病例报告中，我们讨论了一名71岁男性患者，他因直肠腺癌前来我院就诊。在术前腹部计算机断层扫描中偶然发现了一个假性脂肪瘤。我们进行了对比增强超声检查以明确该肿瘤的性质。据我们所知，尚未有关于肝假性脂肪瘤对比增强超声表现的文献报道。
肝假性脂肪瘤在对比增强超声上表现为边界不清、形态规则的稍高回声结节。
根据患者的临床症状、检查结果和影像学表现，该病变被认为是假性脂肪瘤，而非直肠癌肝转移。假性脂肪瘤通常无需治疗。
本报告将有助于增进目前通过对比增强超声成像识别肝假性脂肪瘤的知识，并复习相关文献。
