Chordoid Glioma Originating in the Intrasellar and Suprasellar Regions: Case Report

초록

Chordoid glioma is a rare, low-grade brain neoplasm typically located in the thirdventricle. Herein, we report an unusual case of histologically confirmed chordoidglioma located in the pituitary fossa and suprasellar region, not attached to thethird ventricle. A 57-year-old woman presented with a 2-month history of headacheand visual disturbance. Magnetic resonance imaging revealed an ovoid mass inthe pituitary fossa and suprasellar region, compressing the optic chiasm withoutinvolvement of the third ventricle. The tumor showed low signal intensity on T1-weighted images and iso- to high signal intensity on T2-weighted images, with strongand homogenous contrast enhancement. Subtotal resection was performed via thetranscranial approach, and the patient subsequently received adjuvant gamma kniferadiosurgery. However, the residual mass showed disease progression 5 months afterthe initial surgery.
