Nasoethmoidal Dermoid Cyst With Intracranial Extension. Case Presentation and Surgical Management.

Nasoethmoidal dermoid cysts are rare congenital ectodermal malformations. Unlike other dermoid cysts, those located in the midline can exhibit intracranial extension. Clinically, they may manifest with sebaceous discharge through a fistulous orifice and other morphologic alterations, occasionally presenting with complications at the onset. The authors present a clinical case of a nasoethmoidal dermoid cyst with an intracranial extension, treated with combined interdisciplinary surgical intervention. An adequate imaging evaluation before the surgical planning and complete lesion resection are crucial, considering their high recurrence rates.
