目的：探讨肝脏血管平滑肌脂肪瘤（ＨＡＭＬ）的临床及影像特征。以期通过非创伤性检查正确诊断ＨＡＭＬ。方法：分析４ 例经手术治疗证实及１ 例经肝穿活检证实为ＨＡＭＬ的病例，找出其中在病史及影像学检查方面的共同特点及特征性表现。结果：ＨＡＭＬ具有以下特点：①患者多为女性；②无乙型肝炎病史及肝硬化表现；③Ｂ超检查多认为是良性病变；④ＣＴ平扫及增强对本病的诊断有决定性的作用；⑤ＭＲＩ普通成像及增强对本病的诊断有帮助，而采用脂肪抑制技术可鉴别ＨＡＭＬ与血管瘤；⑥ＤＳＡ对本病的诊断价值不大，仅能提示肿瘤系多血供肿瘤，但有助于其它脂肪瘤鉴别。结论：ＨＡＭＬ的表现具有特征性，只要掌握其特点经过综合分析病史及非创伤性检查结果，作出正确的诊断是可行的。
Objective: To explore the clinical and imaging characteristics of hepatic angiomyolipoma (HAML). With a view to correct diagnosis of HAML through non-invasive tests. Methods: Four cases confirmed by surgical treatment and one case of HAML confirmed by liver biopsy were analyzed to find common features and characteristic features in medical history and imaging examination. Results: HAML has the following characteristics: 1 The patient is mostly female; 2 There is no history of hepatitis B and cirrhosis; 3B ultrasonography is considered to be benign; 4CT plain scan and enhancement have a decisive role in the diagnosis of this disease; 5 MRI Imaging and enhancement are helpful in the diagnosis of this disease, and fat suppression techniques can be used to identify HAML and hemangiomas. 6DSA is of little value in the diagnosis of this disease, and it can only suggest that tumors have multiple blood supply tumors, but contribute to other lipomas Identification. Conclusion: The performance of HAML is characteristic. It is feasible to make a correct diagnosis as long as the characteristics of HAML are comprehensively analyzed and the results of non-invasive examinations are available.
