脑挫裂伤的CT分型探讨(附126例报告)

EXPLORATION OF CT TYPING FOR BRAIN LACERATION

目的探讨脑挫裂伤的CT分型。方法分析126例脑挫裂伤的临床和CT表现。结果Ⅰ型：CT表现为局限性低密度，系局限性水肿所致；Ⅱ型：CT表现为局限性混杂密度，系局限性出血和水肿并存；Ⅲ型；CT表现为局限性高密度.以局限性出血为主;Ⅳ型：CT表现为弥漫性密度，兼有脑室脑池变窄或闭塞，系弥漫性脑肿胀所致；Ⅴ型：CT表现为广泛性混杂密度，可有脑室脑池闭塞和[或]多发性颅内小血肿，系广泛性脑控裂伤所致。结论各型脑挫裂伤的治疗和其预后判定二应重视受伤部位的脑功能状态及其脑挫裂伤CT分型。

Objective To explore the CT typing for the laceration of brain. Method Analysis was performed about the clinical demonstration and CT indications of 126 cases with laceration of brain. Result Type Ⅰ: CT indicater localized density resulted from locolized edema: Type Ⅱ: CT indicates localized mixed density with locolized hemorrhage and edema; Type Ⅲ: CT indicated locolized high density characterized by locolized hemorrhage; Thpe Ⅳ:CT indicates diffuse density accompanied by ventriculo-cisternal narrowing and closing caused by diffuse cerebral tumefaction; Type Ⅴ: CT indicates extensive mixed density with ventriculo-cisternal closing and/or multiple intracranial micro-hematoma resulted from extensive laceration of brain. Conclusion in the treatment and prognosis of brain laceration of all types, attention should be paid to the cerebral functions of the enjured part as well as the CT typing of the brain laceration.
