肝硬化性血管瘤是一种罕见的良性肝脏肿瘤，起源于肝海绵状血管瘤；然而，其形成过程尚不清楚。我们在此介绍一位经组织学证实的肝硬化血管瘤患者，该患者的诊断图像在短时间内显示出巨大的变化。患者，男性，56岁，因疑似丙型肝炎肝细胞癌入院治疗，肝第8段直径约2cm。超声造影最初表现为早期全强化，轻度延迟冲洗；但1个月后在各种诊断图像中表现为周边持续强化，中央无强化区。术前1个月完全戒烟戒酒。未发现提示肿瘤缺血的特殊症状和体征。第 8 节段的解剖切除已完成。组织学检查证实最终诊断为普通型肝硬化血管瘤，源自非典型增强的海绵状血管瘤。在诊断图像和组织学检查中均未观察到血流受损的迹象。肝海绵状血管瘤的硬化性改变可能在相对较短的时间内完成，且没有明显的原因。
Hepatic sclerosed hemangioma is a rare benign liver tumor that originated from hepatic cavernous hemangioma; however, the process of its formation has been unclear. We herein present the patient of a histologically proven hepatic sclerosed hemangioma that showed drastic changes in diagnostic images in a short period. A 56-year-old man was referred to our hospital for the treatment of suspicious hepatocellular carcinoma with hepatitis C, approximately 2 cm in diameter in liver segment 8. Initially, the tumor manifested as early entire enhancement with mildly delayed washout in contrast-enhanced ultrasonography; however, it manifested as continuous peripheral enhancement with the central non-enhanced area after 1 month in various diagnostic images. He completely quit drinking and smoking 1 month preoperatively. No special symptoms and signs were found to suggest tumor ischemia. Anatomical resection of segment 8 was completed. Histological examination confirmed the final diagnosis of common type hepatic sclerosed hemangioma, derived from atypically enhancing cavernous hemangioma. No signs of impaired blood flow were observed in both diagnostic images and histological examination. Sclerosing changes in hepatic cavernous hemangioma may be completed in a relatively short time with no apparent reason.
