Inflammatory hepatic pseudotumor (IHPT) is an important benign liver disease because it is difficult to clinically and radiologically distinguish from malignant tumors.
Here, we describe a case of a 67-year-old male patient diagnosed with multiple inflammatory hepatic pseudotumors. The patient had undergone left hemicolectomy for descending colonic cancer (T3 N0 M0 stage IIA) 2 years prior. He underwent segment 6 and segment 7 partial hepatectomy because of suspected liver metastasis. The patient had an unremarkable postoperative course and was discharged 7days after surgery. Marked infiltration of inflammatory cells was observed on histological examination. The patient was finally diagnosed with IHPT of the fibrohistiocytic type.
Repeated imaging studies over 1 month showed the spontaneous regression of the hepatic tumors. Therefore, knowledge regarding this condition is necessary to allow for treatment, even in the absence of experience. During examination, it may be important to ascertain lesion size. Moreover, percutaneous needle biopsy and follow-up examinations are necessary for cases of suspected IHPT.
Hepatectomy should be considered if the lesion is suspected to be an IHPT.
炎性肝假瘤（IHPT）是一种重要的良性肝脏疾病，因为在临床和影像学上难以与恶性肿瘤区分开来。
在此，我们描述一例67岁男性患者，诊断为多发性炎性肝假瘤。该患者2年前因降结肠癌（T3 N0 M0 IIA期）接受了左半结肠切除术。因怀疑肝转移，他接受了肝段6和肝段7部分肝切除术。患者术后恢复顺利，术后7天出院。组织学检查发现有明显的炎性细胞浸润。该患者最终被诊断为纤维组织细胞型IHPT。
1个月内的重复影像学检查显示肝脏肿瘤自发消退。因此，即使缺乏经验，了解这种情况对于治疗也是必要的。在检查过程中，确定病变大小可能很重要。此外，对于疑似IHPT的病例，经皮穿刺活检和随访检查是必要的。
如果怀疑病变为IHPT，应考虑行肝切除术。
