In 26 of these patients intracavitary brachytherapy was the primary treatment. The follow-up period ranged from 2 to 80 months (41 \u00b1 22 months, mean \u00b1 standard deviation). Five patients died from tumor-related causes. Endocrine recovery was modest.<\/jats:p><jats:p content-type=\"fine-print\">Prior to brachytherapy, visual acuity was diminished in 38 eyes and field defects were present in 46. Funduscopy before treatment revealed optic atrophy in 47% of the eyes. Visual acuity improved in 29% of the eyes studied, remained stable in 13%, and deteriorated in 58%. Visual field defects improved in 28% of the eyes studied, remained stable in 20%, and deteriorated in 52%. The possible causes for deterioration in visual function are discussed.<\/jats:p><jats:p content-type=\"fine-print\">Complete resolution of 10 cysts was noted. In 12 patients the size of the cyst decreased; however, in three of these patients new cyst formation took place. The cyst size stabilized in six cases and increased in three. Although there is still a substantial degree of visual function deterioration following intracavitary brachytherapy, morbidity is otherwise low, making this treatment modality a reasonable alternative to craniotomy.<\/jats:p>","DOI":"10.3171\/jns.1992.77.4.0545","type":"journal-article","created":{"date-parts":[[2009,5,27]],"date-time":"2009-05-27T01:43:38Z","timestamp":1243388618000},"page":"545-550","source":"Crossref","is-referenced-by-count":91,"title":["Intracavitary brachytherapy of cystic craniopharyngiomas"],"prefix":"10.3171","volume":"77","author":[{"given":"J.
