Ten patients with intracranial cystic tumors underwent stereotactic intracavitary irradiation using 32P colloidal chromic phosphate. Accurate dosimetry (25,000-30,000 rad to the cast wall) was achieved by volume estimation using computed tomography. Between 1 and 15 months after surgery both craniopharyngioma and astrocytoma cysts regressed. Neurological, visual, and endocrinological deficits either stabilized or improved. Intracavitary irradiation should be the primary method of treating solitary cystic tumors of the brain.
10例颅内囊性肿瘤患者接受了使用32P胶体磷酸铬的立体定向腔内照射。通过计算机断层扫描进行体积估计实现了精确的剂量测定（囊壁剂量为25,000 - 30,000拉德）。术后1至15个月间，颅咽管瘤和星形细胞瘤囊肿均缩小。神经、视觉和内分泌功能缺损稳定或改善。腔内照射应成为治疗脑内孤立性囊性肿瘤的主要方法。
