The Subtotal Removal of a Suprasellar Dermoid Cyst Expanding Toward the Olfactory Nerves: A Case Report.

Dermoid cysts (DCs) are benign congenital lesions that originate in the ectoderm cells produced during the formation of the neural tube. They are usually located at the cerebral midline, and, on rare occasions, at the suprasellar level. In this case report, we present a 17-year-old female patient with minimal symptoms (hyposmia) caused by a suprasellar dermoid cyst extending toward the anterior cranial fossa and the olfactory nerves with subsequent frontotemporal craniotomy and the subtotal removal of the tumor. Given the rare features of this case, the chosen surgical strategy achieved tumor subtotal resection and symptom remission.
