摘 要:目的 探讨肺血管外皮瘤的影像学表现。方法 分析 3例经病理证实的肺血管外皮瘤的CT、MRI表现。结果 3例患者均表现为肺内单发的巨大肿块 ,CT平扫示密度不均匀 ,强化扫描示肿块实质明显强化 ,并可以见到其中异常强化的血管影。MRI平扫示肿块信号不均匀 ,并可以见到血管流空征象。结论 肺内单发的巨大肿块 ,CT强化扫描见到异常强化的血管 ,MRI扫描见到血管流空征象 。Objective To analyze the imaging features of primary pulmonary hemangiopericytoma,and to provide a helpful method for clinical diagnosis.Methods Retrospectively analyze the CT and MRI characteristics of 3 cases with pathologically proved primary pulmonary hemangiopericytomas.Results All cases manifested as solitary massive tumors.On plain CT scans,the tumors were heterogeneous,well and sharply circumscribed.On contrast-enhanced CT scans,the tumors were apparently enhanced and the abnormally enhanced vasculars could be seen.On MRI scans,the tumors had inhomogeneous signal intensity and the vascular flowing-void effect could be seen.Conclusion Solitary tumor of massive volume,abnormally enhanced vasculars on contrast-enhanced CT and the vascular flowing-void effect on MRI are imaging features of primary pulmonary hemangiopericytomas.
