Hepatic inflammatory pseudotumor (HIPT) is an uncommon benign tumor-like mass that mimics malignant tumors.
A 73-year-old man was admitted with severe epigastric pain and high fever. He had received choledocojejunostomy. Enhanced computed tomography showed a 76 mm, heterogeneous, gradual enhanced low-density mass in the caudate lobe and hyperdense fluid was detected around the mass. Based on the diagnosis of hemorrhage from a hypervascular malignant liver tumor, chemoembolization was conducted. Antibiotics (Meropenem) were administered for 2 weeks, and methylprednisolone (125 mg) was administered twice as a premedication for chemoembolization. After the 2nd chemoembolization, rapid tumor shrinkage was observed and the inflammatory changes gradually disappeared. The tumor was finally diagnosed as fibrohistiocytic type HIPT with an ultrasound-guided percutaneous tumor biopsy. The diameter of the liver tumor decreased to 15 mm and intra-abdominal hemorrhage disappeared in 3 months.
Development of HIPT can be associated with intra-abdominal hemorrhage.
肝炎性假瘤（HIPT）是一种少见的良性肿瘤样肿块，类似于恶性肿瘤。
一名 73 岁男性因严重上腹痛和高热入院。他曾接受过胆肠吻合术。增强 CT 显示尾状叶有一个 76mm、不均匀、逐渐增强的低密度肿块，肿块周围检测到高密度液体。基于肝内富血管性恶性肿瘤出血的诊断，进行了化疗栓塞术。给予抗生素（美罗培南）治疗 2 周，并在化疗栓塞术前行甲泼尼龙（125mg）两次预治疗。第 2 次化疗栓塞术后，观察到肿瘤迅速缩小，炎症改变逐渐消失。最终通过超声引导下经皮肿瘤活检诊断为纤维组织细胞型 HIPT。3 个月后，肝肿瘤直径缩小至 15mm，腹腔内出血消失。
HIPT 的发生可伴有腹腔内出血。
