Multiple chromosomal abnormalities in a case of craniopharyngioma

Craniophyaryngioma is a benign epithelial neoplasm that occurs rarely, comprising only 3% of all intracranial tumors. Cytogenetic study of craniopharyngioma, which appeared to be a slowly growing tumor in vitro, was carried out after 14 days of culture. Twenty cells were analyzed based on trypsin G-banding technique. Results are shown. Both karyotypes most likely represent the endpoints of a long evolutionary process and additional chromosomal studies craniopharyngioma are necessary to reveal the primary chromosomal change or characteristic abnormality for this rare neural tumor.
