Correlation of clinical and pathological features in surgically treated craniopharyngiomas.
Surgical specimens of 104 craniopharyngiomas from 93 patients were reviewed and characterized histopathologically. They were found to have either a classic adamantinous or a squamous papillary structure. The clinical features of each group were then assessed. The frequently solid (50%), always uncalcified squamous papillary tumor type was found in one-third of the adult patients (greater than or equal to 20 years) but did not occur in children. It was associated with a good functional postoperative outcome (84.6%). There have been no cases of tumor recurrence in the squamous papillary group. However, in the group with the adamantinous type of craniopharyngioma, the recurrence rate was 13% in adult patients and 9% in children. When compared to the adult adamantinous cases, the incidence of visual deficits was lower in the squamous papillary group (75% vs. 84%) but the incidence of endocrine abnormalities was higher (75% vs. 52%). Thus, the preoperative, operative, and postoperative features of the two types of craniopharyngioma were found to be distinctly different in adults and children.
