Chondrosarcoma is a mesenchymal tumor composed of tumor cells producing cartilage. It is more common in older age and often affects the axial skeleton. We report a rare case of chondrosarcoma mimicking a sellar and suprasellar mass with parasellar extension. A 40 yr woman presented with decreasing visual acuity and headache. Magnetic resonance (MR) image revealed a cystic sellar and suprasellar...

Two patients with suprasellar cysts and hyperprolactinemia are described. These lesions were diagnosed by CT metrizamide cisternography. Suprasellar cysts are a rare cause of pathologic hyperprolactinemia, which most commonly results from pituitary adenomas. Tissue diagnosis revealed suprasellar arachnoid cysts in the first patient and Rathke's cleft cyst in the second. The differential diagnos...

OBJECTIVE Suprasellar meningiomas have been resected via various open cranial approaches. During the past 2 decades, the endoscopic endonasal approach has been shown to be an option in selected patients. We wished to examine the learning curve for parameters such as extent of resection, visual outcome, and complications. METHODS We retrospectively reviewed a consecutive series of patients in ...

Though craniopharyngioma remains the most common sellar suprasellar tumor with calcification, it can be seen very rarely in pituitary adenomas and Rathke's cleft cysts. Appreciation of the pattern of calcification in a sellar suprasellar lesion can give a clue to the nature of the lesion. The authors describe a 53-yearold male with a cystic sellar suprasellar lesion and curvilinear calcificatio...

Background: Glial fibrillaryacidic protein (GFAP), an intermediate filament protein, is mainly expressed by astrocytes, but some other cells like enteric glia and non-myelinating Schwann cells can also express GFAP. GFAP elevation has been reported in some types of meningioma and malignant brain tumors. In the present study, we analyzed the association between serum levels of GFAP with meningio...
