Computerized tomography(CT) of the brain allows the clinical diagnosis of intracerebral . hemorrhage or cerebral infarction. The size, location and extension of lesion are acurately portrayed.
At kyung Hee medical center in this year, prognosis of 71 cases with cerebral infarction and 71 cases with cerebral hemorrhage has been studied in relation to the lesion on CT scan. It has been important prognostic index whether to involve or not to involve posterior limb of internal capsule. The results were summerized as follows.
1) Motor deficit was mild in patients with the brain lesion, which is not involving internal capsule(Motor function 73°0), whereas patients with lesion in the posterior limb of internal capsule had much more marked motor involvement(Mf. 12%).
2) In the case involving internal capsule, nearly all of the patients with cerebral infarction had complete hemiplegia(Mf. 15%), whereas there was slight improvement in the patients with cerebral hemorrhage(Mf. 30%). On the other hand, the patients with the lesion not involving internal capsule had a good recovery(Mf..86°0).
3) The prognosis of hemiparesis was unfavorable in patients with the lesion involving internal capsule than the other lesion by CT scan.
