Surgical treatment of anterior callosal tumors.

OBJECTIVE: Thirteen patients with neoplasm of anterior corpus callosum have undergone our observation during the last two years. METHODS: For the diagnosis, all the patients underwent TC, NMR and stereotactic biopsy. In 6 cases with glioblastomas, a radiation treatment was adopted. The other 7 patients underwent total surgical treatment in 5 cases, and partial in 2 cases, as documented by postoperative contrast-enhanced CT scanning. Histologically, there were: 3 glioblastomas, 1 grade III astrocytoma, 1 neuroblastoma (PNET), 2 pilocytic astrocytomas. RESULTS: Neuropsychological tests carried out on the 5 patients still living showed persistent disturbances of verbal memory in all five and disturbances of verbal phonological fluency in 3 cases. No patient presented apraxia, dysgraphia and dyslexia. CONCLUSIONS: Thus, no severe neuropsychological deficits developed after surgical treatment of anterior callosal tumors.
