Presented below are the author s report of the result of surgical treatment of 53 intramedullary gliomas. In the anaysis of survival data. twenty patients with low grade glioma(except the ependymoma) were followed for a period of mean 54 months, from 1 to 103 months. Five of these patients had died from progression of the disease and the 5 year survival rate was 75%. Nine pateints from the above group recieved postoperative radiation therapy.6 with no apparent benefit in terms of survival rate. The median survival of thirteen patients with high grade glioma patients were 11 months and there were signficant increase of median survival time in patients recieving radiation therapy, from 4 to 17 months(P=0.04) The histological grade is the important factor in determining the survival of glioma pateints(P=0.01). In sixteen, out of 20 ependymoma patients, radical removal(>95%) was achived and the patients showed no signs of recurrence until the mean follow-up period of 42 months. Two of the 4 ependymoma patients, whose tumors were partially removed, suffered recurrence and had to be re-operated. We concluded that the radical removal in epndymomas is a significant factor in determining recurrence(P=0.009). The effect of radical removal on survival is not verified statistically. Total removal is more frequently performed in ependymomas than in gliomas(p=0.03). As to functional outcome, better outcome is expected in radical removal on long-term follow-up(p=0.00506)). more so in ependymoma than in glioma. lntramedullary gliomas are extremely rare Therefore sufficient data is unavailable for the determination of efficient treatment plan. However, recently, aggressive surgical treatment with the aid of microsurgical techniques has become a trial option.

Sellar arachnoid cysts are rare; an infected arachnoid cyst is extremely rare as only one case has been reported to date in the literature. Here, we report a patient with an infected or inflamed sellar arachnoid cyst that was successfully treated with transsphenoidal surgery (TSA). A 53-year-old female with a his-tory of chronic sinusitis developed a headache 5 months ago, and one month before admission poly-uria, polydipsia, and abnormal vaginal bleeding occurred. The magnetic resonance imaging (MRI) showed a sellar cystic mass with a thickened pituitary stalk. Preoperative hormonal study revealed nor-mal pituitary hormone levels except for a moderate elevation of prolactin. She was diagnosed with dia-betes insipidus of the central nervous system origin based on a water-deprivation test. TSA was per-formed under an impression of symptomatic Rathke`s cleft cyst according to the MRI findings. Intraoperative findings showed confirmation of turbid intracystic contents, but micro-organisms were unidentified on microbial culture. Pathology of the cyst wall revealed inflamed meningoepithelial lining cells compatible with an arachnoid cyst.
