title: Hyperdense suprasellar mass: An unusual radiological presentation of intracranial dermoid cyst.
abstract: We report an exceedingly rare patient with a hyperdense suprasellar dermoid cyst and a pertinent review of the literature. Intracranial dermoid tumors are rare congenital lesions of the brain that account for less than 1% of all intracranial tumors. Even though they are rare, typical CT scan and MRI features and location allow radiological diagnosis in the majority of patients. Radiologically, dermoid cysts typically present as low density masses on CT scan and are generally hyperintense on T1-weighted MRI sequences with variable signal on T2-weighted sequences. The recognition of atypical features can avoid diagnostic pitfalls and is clinically relevant for overall surgical management.
