摘　　要：目的 :探讨迟发性脑挫裂伤的早期CT诊断。方法 :收集CT复查证实的外伤性迟发性脑挫裂伤 4 6例 ,对其首次CT检查及复查的CT影像特点进行分析。部分病例采用薄层CT扫描和短期内复查CT。结果 :首次CT扫描显示 :局限性脑沟、脑裂变浅及消失 2 7例 ,脑池模糊不清 ,脑室受压变小 17例 ,头皮较大血肿 38例 ,颅骨骨折 5例 ,颅内伴发病变 9例。结论 :注意早期征象 ,适时CT复查 。Objective:To explore the early CT diagnosis of delayed cerebral contusions and lacerations. Methods: Forty six delayed traumatic cerebral contusions patients confirmed by CT rescan were collected and their imaging features of the initial CT scan and re examination were analyzed. The thin slice CT scans and CT re examination were done in some cases within a short term. Results: The initial CT showed that local cerebral sulcus and fissures became shallow or disappeared in 27 cases, indistinct cisterna and ventricular compression in 17 cases, larger scalp hematoma in 38 cases, skull fractures in 5 cases, other intracranial concomitant lesions in 9 cases. Conclusion: It is helpful to pay attention to diagnosing the early signs and symptoms, appropriately re examine with CT scan and thin slice CT scan.
