纵隔血肿的 CT诊断

目的 分析纵隔血肿的CT表现，以提高其诊断水平。资料与方法 回顾性分析19例经临床、手术证实的纵隔血肿资料。结果 前纵隔血肿8例，其中片状血肿6例，结节状血肿1例，团块状血肿1例；中纵隔血肿2例，均呈结节状；后纵隔血肿4例，其中片状血肿2例，团块状血肿2例；弥漫性纵隔血肿5例，均呈片状。结论 心脏大血管的损伤往往导致弥漫性纵隔血肿，小血管损伤导致的纵隔血肿大多比较局限。CT扫描对于纵隔血肿的诊断具有重要价值。

CT Diagnosis of Mediastinal Hematoma

Objective To analyze CT features of mediastinal hematoma in order to improve the accuracy of in diagnosing.Materials and Methods CT images of 19 cases with mediastinal hematoma, confirmed by clinical data, surgery, were retrospectively analyzed. Results Anterior mediastinal hematoma in 8 cases, included opacities (n=6), nodular (n=1), mass (n=1); middle mediastinal hematoma in 2 cases, as nodular shadows; posterior mediastinal hematoma in 4 cases, included opacities (n=2), mass (n=2); diffuse mediastinal hematoma in 5cases, as opacities shadows.Conclusion Large vascular injuries main cause diffuse mediastinal hematoma, and small vascular injuries main cause focal mediastinal hematoma. CT is a good method for diagnosing mediastinal hematoma.
