ABSTRACT

In order to determine the survival rate and prognostic factors of patients with intracranial oligodendroglioma as predictors of survival, a retrospective analysis of a total of 68 cases treated between 1982 and 1992 at our institute was performed. The 5-year and 10-year survival rates were 84.5% and 55.1% respectively while the median survival time was 116+/-5.3 months. The significant factors identified by the univariate analysis included the presence of preoperative seizure, the pre- and postoperative status, the presence of signs of increased intracranial pressure before operation and pathologic grade of the tumors. Factors such as age, types of chief complaints, blood types, the preoperative neurologic deficit, the size of tumor, the enhancement of tumor, cysts in tumor, the extent of removal and the postoperative seizure had no correlations with survival rates. The only significant prognostic factor determined by the multivariate analysis was the pathological grade(p=0.04).

ABSTRACT

An encepholocele is defined as a herniation of cranial contents through a defect in the skull. Encephaloceles are classified accroding to their contents and location. Encephalocele is a useful general term to refer to common features of the various forms of anomaly, but considerable differences exist in the pathology, treatment and prognosis of encephaloceles at each anatomical location. Improved neuroimaging facilities, especially MRI, make it easy not only to detect the encephalocele including its contents and location, but also to get preoperative informations. We have reviewed a total of 22 patients with encephalocele whom we have experienced from 1986, July to 1990, June. Twelve were at occipital location, six at cranial vault, three at cranial base, one at frontoethmoidal location. The size of cranium bifidum and herniating sac of the cranial vault and occipital location is larger than that of frontobasal location. The incidence of associated hydrocephalus is in order of occipital, cranial vault, frontobasal form, and its prognosis is also better in frontobasal form than in occipital of cranial vault form.
