摘　　要：目的通过回顾性分析儿童肝脏实性间叶性错构瘤的超声表现及其临床病理基础，探讨儿童肝脏实性间叶性错构瘤的超声学特点，提高术前诊断正确率。方法收集我院经病理证实的实性肝脏间叶性错构瘤8例，其中男3例，女5例，年龄3d～9岁5个月（中位年龄为7个月）。8例均因“腹部包块”就诊。术前均进行灰阶超声和彩色多普勒检查。结果本组8例均为单发肿瘤，肿瘤位于右叶4例，位于左叶3例，累及两个肝叶1例。声像图表现为中等偏强回声2例，中等回声6例，回声不均者7例，6例可见大小不等的低回声灶，3例部分强光点伴声影。彩色多普勒检查提示，1例肿瘤内血流丰富，6例可见少量血流，1例未见血流。所有病例均可见肿瘤推压相邻血管，使之变形、移位。结论儿童实性肝脏间叶性错构瘤声像图表现多样，反映了大体病理学变化，了解其声像特征有助于早期诊断。Objective To investigate the features of ultrasonography （US） of solid hepatic mes- enchymal hamartoma （SHMH） in children. Methods Eight patients with SHMH, which was con- firmed by postoperative pathology, were enrolled in this study. Among them, 3 were males and 5 were females. Their age ranged from 3 days to 9 years and 5 months old （median age, 7 months old）. All patients presented with palpable abdominaI mass but without jaundice. Ultrason0graphy was per- formed on all patients before operation. Intratumoral vascularity was evaluated by Doppler US. Results Among the 8 patients, an isolated hepatic mass was found in the,right lobe in 4 patients, in the left lobe in 3 patients and the isolated mass involving both lobes in 1 patient. On ultrasonography, the SHMH of 6 patients presented iso-echogenicity, and the other 2 had iso- to high-echogenicity. Hetero- geneous echo in the tumor was found on 7 patients, low echo fuci with variable size were seen in 6 pa- tients and high echo points with sound shadow were found in 3. On color doppler ultrasonography, 6 masses had small amount blood flow, 1 with abundant blood, and the other one had no blood flow. The blood vessels in the vicinity of the tumor were displaced. Conclusions A solid hepatic mesenchy- real hamartoma in children can present a wide spectrum of ultrasonographic features which are correla- ted with the postoperative pathological findings.
