Suprasellar teratoma

Discussion:

The lesion was biopsied. There were epithelial elements, underlying connective tissue with sebaceous glands, and fat, consistent with a mature teratoma. There were no immature or malignant components.

Intracranial teratomas are midline tumors which may contain calcium, soft tissue, cysts and fat. They occur from the optic chiasm to pineal regions. They may be mature, immature or malignant, depending on the degree of differentiation. Differential diagnoses include craniopharyngioma, dermoid and non-germinoma germ cell tumor.
