Abstract
A case of a craniopharyngioma confined entirely to the third ventricle is reported. MRI revealed an isointense and high signal lesion on T1- and T2-weighted images, respectively, with homogeneous enhancement by Gd-DTPA. The tumor was reduced by 90% in 4 months after 60 Gy radiation therapy. Intraventricular craniopharyngioma is unusual and is not associated with tumoral calcification or cyst formation.
摘要
报告了一例完全局限于第三脑室的颅咽管瘤病例。磁共振成像（MRI）显示，在T1加权像和T2加权像上分别为等信号和高信号病变，经钆喷酸葡胺（Gd-DTPA）增强后呈均匀强化。60 Gy放射治疗4个月后，肿瘤缩小了90%。脑室内颅咽管瘤较为罕见，且与肿瘤钙化或囊肿形成无关。
