Abstract：
BACKGROUND: Hepatic myopericytoma (MPC) is an extremely rare pathological entity in the liver. Conversely, cystic hepatic lesions are a group of heterogeneous lesions encountered commonly in daily practice. Here, we report a unique case of the coexistence of primary hepatic MPC and multiple cystic hepatic lesions along with our perceptions on its diagnosis and treatment.
METHODS: A 56-year-old female patient was found to have a left liver mass during a routine physical examination. Computer tomography (CT) and magnetic resonance imaging (MRI) confirmed the existence of a left hepatic neoplasm along with multiple hepatic cysts but could not exclude the possible malignant nature of the neoplasm. Computer tomography (CT) also identified an enlarged mediastinal lymph node with a maximum diameter of 4.3 cm, which further underwent core needle biopsy under CT guidance. A histopathological examination was performed to rule out malignancy. Afterwards, the patient underwent left hemihepatectomy to resect a solid tumor of 5.5 cm × 5 cm × 4.7 cm with multiple cystic lesions which were histopathologically examined to establish the diagnosis of myopericytoma with hepatic cysts. Postoperatively, the patient recovered from the surgery quickly without significant adverse events and was not found to have a reoccurrence of the primary pathological entity.
CONCLUSIONS: This is the first reported case of a patient with the co-existence of primary hepatic myopericytoma and multiple cystic hepatic lesions undergoing surgical treatment with eventual recovery.

摘要：
背景：肝肌皮细胞瘤（MPC）是肝脏中极为罕见的病理实体。相反，肝囊性病变是一组在日常实践中经常遇到的异质性病变。这里,我们报告了原发性肝MPC和多发性囊性肝病灶共存的独特病例，以及我们对其诊断和治疗的看法。
方法：一名56岁的女性患者在常规体格检查中发现左肝肿块。计算机断层扫描（CT）和磁共振成像（MRI）证实存在左肝肿瘤以及多个肝囊肿，但不能排除肿瘤可能的恶性性质。计算机断层扫描（CT）还确定了纵隔淋巴结肿大，最大直径为4.3cm，在CT引导下进一步进行了芯针活检。进行组织病理学检查以排除恶性肿瘤。之后,患者接受左半肝切除术，切除了5.5cm×5cm×4.7cm的实体瘤，并进行了组织病理学检查，以确定诊断为肝囊肿的肌周细胞瘤。术后,患者从手术中迅速康复,无明显不良事件发生,且未发现原发病理实体复发.
结论：这是首例报告的原发性肝周细胞瘤和多囊性肝病变并存的患者，接受手术治疗并最终恢复。
