摘　　要：目的:探讨CT检查对脾创伤的诊断价值,着重讨论CT增强扫描在脾创伤诊断中的应用。方法:回顾分析43例脾创伤的CT表现,其中14例行CT平扫检查,29例行CT平扫和增强扫描。结果:包膜下血肿17例(40%),表现为脾脏外缘新月形的血肿影;脾实质挫裂伤22例(51%),表现为脾实质内线条状或类圆形低密度血肿影;脾实质挫伤伴脾蒂断裂2例(5%),表现为脾脏失去正常形态,伴脾门血管受损;假阳性2例(5%)。结论:CT检查能作出脾创伤的诊断和分型,为临床治疗提供重要信息。Objective：To investigate the clinic value of CT in the diagnosis and classification of splenic trauma and to evaluate the importance of contrast enhanced CT scan in diagnosing the disease. Methods：43 cases with splenic trauma were reviewed retrospectively. Plain CT were performed in 14 cases, and plain and contrast enhanced CT were performed in 29 cases. Results： Subeapsular hematoma in 17 eases（40%） appeared as low-density fluid collections shaped like a crescent. Splenic laceration in 22 cases（51 %） appeared as low-density linear fractures, splenic fragmentation, or intrasplenic hematomas. Splenic laceration with rupture of splenic vessel in 2 cases（5 % ） appeared as irregular contour of spleen, vascular injury involving the splenic pedicle. Two examinations were false-positive cases（5 % ）. Conclusion：Definite diagnosis and classification can be made by CT, providing the important information in clinical therapy of the disease. Contrast enhanced CT scan is necessary in the diagnosis of splenic trauma.
