CASE
A 77-year-old woman was referred to our hospital for detailed examination of a cystic liver tumor. Contrast-enhanced CT and MRIshowed a cystic liver tumor with an enhanced mural nodule in S6 of the liver. Under a preoperative diagnosis of hemorrhagic hepatic cyst and mucinous cystic neoplasm(MCN)of the liver, extended posterior segmentectomy was performed. Histological examination of the tumor revealed no neoplastic cells, and the tumor was finally diagnosed as a hemorrhagic hepatic cyst of the liver.
CONCLUSION
Similar to previous reports of hemorrhagic hepatic cysts, preoperative differential diagnosis from MCN of the liver was difficult in this case. Hemorrhagic hepatic cysts are rare and are sometimes confused with MCN of the liver, especially when an enhanced mural nodule is found in the cyst. The possibility of hemorrhagic hepatic cysts should be considered during diagnosis of liver cystic tumors.
病例
一名77岁女性因肝囊性肿瘤的详细检查被转诊至我院。增强CT和MRI显示肝脏S6段有一个伴有壁结节强化的肝囊性肿瘤。在术前诊断为肝出血性囊肿和肝黏液性囊性肿瘤（MCN）的情况下，实施了扩大的肝后段切除术。肿瘤的组织学检查未发现肿瘤细胞，最终该肿瘤被诊断为肝出血性囊肿。
结论
与先前关于肝出血性囊肿的报道相似，本病例中术前难以将其与肝MCN进行鉴别诊断。肝出血性囊肿罕见，有时会与肝MCN混淆，尤其是当囊肿内发现壁结节强化时。在诊断肝囊性肿瘤时应考虑肝出血性囊肿的可能性。
