The CT scans of 18 patients (12 males and 6 females; mean age: 43.6 years) with splenic blunt trauma were reviewed. CT examinations had been made at different times after trauma. The CT images were grouped according to the time of examination and both structure and densitometry were evaluated in all lesions. In all cases CT findings were correlated with surgical and pathologic data. The patients were divided into two groups: group I included 11 subjects in whom CT had been performed within 48 hours following trauma and group II included 7 patients who had undergone CT at different times after trauma (3-13 days; mean: 6.5 days). All the lesions in group I exhibited blurred outlines, while the lesions in group II had clear-cut margins. The lesions in group I were always hyperdense while those in group II were hypodense. CT diagnosis was always in agreement with surgical findings. In conclusion, we confirm the value of CT in the examination of splenic lesions by blunt abdominal trauma. The evolution of splenic lesions is usually typical: CT yields useful information for injury evaluation and is therefore very important to plan treatment. We believe that CT should be performed as soon as possible, even on the basis of minor clinical and laboratory data.
回顾了18例脾钝性外伤患者（12例男性，6例女性；平均年龄：43.6岁）的CT扫描结果。CT检查在创伤后的不同时间进行。根据检查时间对CT图像进行分组，并对所有病变的结构和密度测定进行评估。所有病例的CT表现均与手术及病理数据进行对照。患者分为两组：第一组包括11例在创伤后48小时内进行CT检查的患者，第二组包括7例在创伤后不同时间（3 - 13天；平均：6.5天）进行CT检查的患者。第一组所有病变的边界均模糊不清，而第二组病变的边界清晰。第一组病变总是高密度的，而第二组病变是低密度的。CT诊断始终与手术结果一致。总之，我们证实了CT在腹部钝性外伤所致脾病变检查中的价值。脾病变的演变通常具有典型性：CT可为损伤评估提供有用信息，因此对制定治疗方案非常重要。我们认为，即使基于轻微的临床和实验室数据，也应尽快进行CT检查。
