대뇌겸 및 천막부위의 경막하출혈에 대한 전산화단층촬영 = CT Finding of Falcial and Tentorial Subdural Hemorrhage

다국어 초록 (Multilingual Abstract)

Computed tomography has been established as an indispensable tool in the detection of intracranial hemorrhages., Extraaxial fluid collections are usually easily distinguished from intracerebral hemorrhages. However, hemorrhages in atypical locatios, such as in falx and tentorial regions, can be difficult to diagnose with CT. RESULT : 1. In 589 cases of intracranial hemorrhage, the incidence of subdural hemorrhage was 372 cases (63.2%). 2. Among 372 cases with subdural hemorrhage, 84 cases had falcial &/or tentorial subdural hemorrhage. 3. The location of falcial subdural hemorrhage was anterior in 30 cases, posterior in 15 cases and middle in 5 cases. 4. The location of tentorial subdural hemorrhage was petrous edge in 7 cases, occipital attachment in 6 cases, tentorial hiatus in 5 cases, and diffuse in 3 cases. 5. In 13 cases showing combined falcial & tentorial subdural hemorrhage, there was 3 cases of postrior falx & tentorial hiatus, 2 cases of anterior falx & petrous edge 2 cases of anterior falx & tentorial hiatus, 2 cases of posterior falx & petrous edge, 2 cases of posterior falx & occipital attachment, 1 case of posterior falx & diffuse, and 1 case of posterior, middle falx & diffuse. 6. In the cases with cfalcial &/or tentorial subdural hemorrhage, the incidence of associated intracranial hemorhage were intracrania subdural subdural hemorrhage in 40 cases, hemorrhagic brain contusion in 16 cases, subarachnoid hemorrhage in 11 cases, epidural hemorrhage in 9 cases, combined subarachnoid & intracerebral hemorrhage in 5 cases, & combined subdural & epidural hemorrhage in 3 cases. 7. The prognosis of falcial &/or tentorial subdural hemorrhage was related to degree and location of associated intracranial hemorrhage, and surrounding brain edema, contusion or both, but the existence, locatin, and amount of falcial &/or tentorial subdural hemorrhage itself were not affected motality and morbidity.
