Hepatic inflammatory pseudotumor (IPT) is a rare lesion that is frequently confused with malignant tumors. According to the latest guidelines on contrast-enhanced ultrasound, hypoenhancement of solid lesions in the portal and late phases corresponds to the wash-out phenomenon that characterizes malignancies. IPT may show rapid arterial enhancement and portal or late phase hypoenhancement, falsely suggesting malignancy. We report a case of a diagnostic error in which a multifocal IPT was misdiagnosed as hepatic metastases. The IPT developed after an endoscopic retrograde cholangiography was investigated by close follow-up with CEUS and contrast-enhanced CT.
肝脏炎性假瘤（IPT）是一种罕见病变，常与恶性肿瘤相混淆。根据最新的超声造影指南，实性病变在门静脉期和延迟期呈低增强对应于恶性肿瘤所特有的廓清现象。IPT可能表现为动脉期快速增强及门静脉期或延迟期低增强，从而错误地提示为恶性肿瘤。我们报告一例诊断失误病例，其中多灶性IPT被误诊为肝转移瘤。通过超声造影（CEUS）和增强CT密切随访，对在内镜逆行胆管造影术后发生的IPT进行了研究。
