婴幼儿胸壁错构瘤的影像诊断

Diagnosis of chest wall hamartoma in infancy

目的:探讨婴幼儿胸壁错构瘤(MHCW)的临床影像特征。方法:回顾性分析2例病理确诊为MHCW婴儿的临床影像资料。2例患儿临床表现为发热、咳嗽,均行胸部X线正侧位片及CT增强扫描。结果:2例患儿胸片均表现为左侧胸腔类圆形密度不均肿块,受累肋骨受压变形。CT显示肿物源自肋骨,境界清晰,内见高密度钙化样密度影,中心肋骨膨胀变形,增强后肿物部分区域轻度强化。结论:MHCW的影像表现具有一定特征性,确诊需依靠组织病理学检查。

Objective：To analyze the clinical and imaging features of mesenchymal hamartoma of the chest wall（MHCW）.Methods：The clinical and imaging materials of 2 cases with surgery and pathology proven MHCW were re-rospectively analyzed.There were complete chest radiography and CT data in 2 cases.Results：Radiography in both cases revealed a large round inhomogenous mass in left thorax,with rib deformity.CT showed a partially calcified well-defined dense mass arising from one rib,with expansion and deformity of the rib.There was mild enhancement of the mass after administration of contrast medium.Conclusion：Certain characteristic imaging features of MHCW could be assessed and could help to diagnose;the definitive diagnosis will be established only by histopathological examination.
