Chordoid glioma, a recently introduced clinicopathologic entity, is a rare neoplasm occurring mainly in the third ventricle and hypothalamus. The authors had experienced a case of chordoid glioma combined with Rathke's cleft cyst which occurred in the sellar and suparasellar region. Here we report clinical, radiological, and histopathological features of this neoplasm with review of literature

For assessment of the feasibility of histopathological diagnosis on the basis of CT findings in suratentorial gliomas, 60 consecutive histologically proven cases were analysed. Benign astrocytomas(Kernohan's grade I, I-II, II) were 25, Oligodendrogliomas 6, malignant gliomas(Kernohan's grade III, III-IV, GM) 29 in number. Plain CT findings and degree of peritumoral edema were less significant than the patterns of contrast enhancement in predicting the histological malignancy. Calcification, if present, excluded the diagnosis of malignant gliomas. Combining the CT criteria of pattern of contrast enhancement, degree of peritumoral edema with angiographic signs of malignancy in addition to the clinical feature, a more confident histological diagnosis seemed allowable.

We report a case of solitary primary leptomeningeal glioma. The mass was totally removed under awake surgery. Intraoperatively, no parenchymal involvement was noted. Histopathological study revealed a predominant anaplastic oligodendroglioma component and a focal anaplastic astrocytoma component, which was consistent with an anaplastic oligoastrocytoma. Adjuvant tomotherapy was followed and the tumor has not recurred until 12 months after surgery. A focal type of primary leptomeningeal glioma is extremely rare. We report a rare case of solitary primary leptomeningeal anaplastic oligoastrocytoma.

To assess the degree of malignancy in cerebral gliomas at the time of diagnosis, we compared the metabolic ratio using 18F-fluorodeoxyglucose(FDG)-Positron Emission Tomography(PET) with histologic grading and proliferative index(Ki-67) of cerebral gliomas. Materials for this study were histologically-examined 21 gliomas and they were divided into glioblastomas as group 1, anaplastic gliomas as group 2, and low-grade gliomas as group 3. The visual analysis of FDG-PET images showed hypermetabolic lesions in 14(87.5%) out of 16 high-grade gliomas (glioblastomas and anaplastic gliomas), and hypometabolic lesions in 4(80%) out of 5 low-grade gliomas. Tumor to cerebellum ratio(T/Cbll) in FDG-PET was used as metabolic ratio and the values of T/Cbll in each group were 1.30+/-0.10, 0.73+/-0.07, 0.70+/-0.07, respectively. In comparision of T/Cbll between group 1 with remaining two groups, differences were statistically significant(p=0.0002, p=0.0002, respectively), however, there was no statistical difference between group 2 and group 3. The values of Ki-67 were 24.16+/-5.66 in group 1, 8.10+/-2.70 in group 2, 5.46+/-1.23 in group 3, and differences were statistically significant between group 1 and group 2, 3(p=0.015, p=0.015, respectively), but there was no statistical difference between group 2 and group 3. The correlation between T/Cbll and Ki-67 was good and statistically significant(p=0.0047). In conclusion, the visual and semiquantitative analysis of FDG-PET would be helpful in determining the degree of malignancy in cerebral gliomas.
