title: Nasal dermoid with intracranial extension.
abstract: Nasal dermoids are rare congenital anomalies, which usually present in early childhood as a midline nasal mass that requires surgical management. It is important to rule out any intracranial extension before subjecting the patient to surgery. We describe a case of nasal dermoid with intracranial extension. The embryology of the formation of the nasal dermoid, cyst and sinus, with the role of CT scan and MRI in diagnosing intracranial extension, and its management are discussed.
