title: [Cystic craniopharyngiomas: computed tomography in the pretherapeutic evaluation and control of treatment results following intracystic contact irradiation].
abstract: A report is given on the treatment planning by computed tomography and monitoring in 37 cases of preponderantly cystic craniopharyngiomas with different solid tumor parts. Colloidal yttrium 90 silicate was used for the intracystic contact irradiation. Two pretherapeutic forms of the solid tumor parts were found in CT examination which correlated with different courses: 1. the polymorphic type and 2. the type with a smooth outline. A posttherapeutic decrease of the cystic volume was observed in 74% of type 1 cases (n = 19) and in 89% of type 2 cases (n = 18). An increase in volume was only found in type 1 (21%). An increase of the solid tumor part was also found exclusively in the polymorphic type (68%). An additional external irradiation should be considered for this CT manifestation of the tumor, as the solid tumor part is not exposed in intracystic contact irradiation.
