迟发性外伤性脑内血肿的早期CT征象

本文对５６例迟发性外伤性脑内血肿（ＤＴＩＣＨ）的首次ＣＴ扫描影像进行了回顾性分析总结，其早期征象为：１．脑挫裂伤伴散在出血；２．外侧裂池积血征；３．脑沟积血征；４．脑挫裂伤伴前纵裂积血征；５．上述征象均伴有脑受压表现。ＤＴＩＣＨ最常见于对冲伤的额叶和颞叶，多发生于外伤的急性期。本文结合文献提出了早期确诊ＤＴＩＣＨ行ＣＴ复查或手术探查的指征。

Early CT Signs of Delayed Traumatic Intracerebral Hematoma

The initial CT scanning of 56 cases with delayed traumatic intracerebral hematomas (DTICH) were reviewed retrospectively. The early CT signs were as followed:1. cerebral contusions accompanied by scattered hemorrhage;2. hemorrhage in sylvian fissure;3. hemorrhage in cerebral fissure;4. hemorrhage in longitudinal fissure accompanied by cerebral contusions;5. the signs mentioned above were accompanied by compression of the brain. DTICH mostly occurred in the frontal and temporal lobe caused by contrecoup injury and in the acute stage. On basis of our data and previous literature, we proposed the indications of repeated CT scanning or exploring operation for early diagnozing DTICH.
