目的探讨纵隔海绵状血管瘤(CHM)的多层螺旋CT表现及其与病理基础的相关性,以期进一步提高CT诊断的准确性。方法收集2008年11月-2013年11月行手术并经病理证实的4例CHM患者资料。4例术前均行多层螺旋CT平扫及增强检查,重点观察CHM的CT表现及其影像-病理相关性。结果 4例海绵状血管瘤,2例位于前纵隔,2例位于后纵隔。2例密度较均匀,2例平扫密度明显不均匀。增强扫描4例病灶内均见明显强化的血管。结论 CHM多发生在前、后纵隔,病灶内的钙化及增强的血管影是该病的特征,多层螺旋CT能准确反映该特点及其病理特征,提供更多诊断信息。
Objective To investigate the multi-slice spiral CT findings of mediastinal cavernous hemangioma (CHM) and its correlation with pathological basis in order to further improve the accuracy of CT diagnosis. Methods The data of 4 CHM patients surgically and pathologically confirmed from November 2008 to November 2013 were collected. In 4 cases, multi-slice spiral CT scan and enhanced examination were performed preoperatively. The CT findings of CHM and its imaging-pathological correlation were observed. Results Four cases of cavernous hemangiomas, two in the anterior mediastinum and two in the posterior mediastinum. 2 cases of more uniform density, plain density of 2 cases was significantly uneven. Enhanced scanning in 4 cases showed lesions were significantly enhanced blood vessels. Conclusion CHM occurred in the anterior and posterior mediastinum, calcification and enhanced vascular lesions within the lesions is characterized by multi-slice spiral CT can accurately reflect the characteristics and pathological features, to provide more diagnostic information.
