Abstract
A meningioma of the tela choroidea of the third ventricle is rare. CT and detailed analysis of angiographic findings in such a case are presented. CT facilitated the detection of rough location of the tumor and the prediction of its histological features. Carotid and vertebral angiographies were utilized in detailing the three-dimensional, gross anatomical relationship between tumor and the surrounding brain structures. Vertebral angiography also contributed to predicting the histology of the tumor.
