目的探讨超声在肝上皮样血管内皮瘤(HEHE)诊断中的价值。方法对29例经病理证实为HEHE患者的超声图像进行回顾性分析,研究肿瘤的大小、位置、回声、边界、内部结构以及彩色多普勒血流信号特点。结果 29例HEHE患者共132个病灶,直径范围1~6.8cm,高回声病灶25个,低回声病灶36个,稍低回声病灶66个,等回声病灶5个。81个病灶回声欠均匀,51个病灶内部回声尚均匀;52个病灶边界欠清,26个病灶边界不清,54个病灶边界尚清。10例患者较大病灶周边伴晕环,6例患者伴钙化,4例患者病灶之间互相融合,9例患者显示周边彩色血流信号,11例患者显示周边及内部均有彩色血流信号,18例动脉血流,2例静脉血流,平均阻力指数(RI)0.63±0.06。结论灰阶超声结合彩色多普勒超声对于肝脏上皮样血管内皮瘤的诊断具有一定的帮助。
Objective To investigate the value of ultrasound in the diagnosis of hepatic epithelioid hemangioendothelioma (HEHE). Methods Twenty - nine patients with HEHE confirmed by pathology were retrospectively analyzed. The size, location, echo, boundary, internal structure and color Doppler flow characteristics of the tumor were studied. Results A total of 132 lesions were found in 29 patients with HEHE. The diameter ranged from 1 to 6.8 cm. There were 25 hyperechoic lesions, 36 hypoechoic lesions, 66 hypoechoic lesions and 5 echogenic lesions. The echo of 81 lesions was not uniform, and the internal echo of 51 lesions was uniform. The boundary of 52 lesions was not clear, the boundary of 26 lesions was unclear, and the boundary of 54 lesions was clear. Among the 10 patients, halo around the larger lesion, 6 patients with calcification, 4 patients fused with each other, 9 patients showed peripheral color flow signals, 11 patients showed peripheral and internal color flow signals, 18 cases of arterial blood flow, 2 cases of venous blood flow, the average resistance index (RI) 0.63 ± 0.06. Conclusion Gray-scale ultrasound combined with color Doppler ultrasound for the diagnosis of hepatic epithelioid hemangioendothelioma has some help.
