Rupture of a Posterior Fossa Dermoid Cyst Overlying the Torcular with Extracranial Extension: Technical Note
ABSTRACT
Intracranial dermoid cysts are congenital benign neoplasms mostly diagnosed in the pediatric hood and usually involve the midline structures. They count approximately less than 1% of all intracranial neoplasms and are believed to arise from ectopic cell rests incorporated in the closing neural tube. These dermoid cysts, especially those involving the posterior fossa and overlying the torcular, are uncommon. We report perhaps the first case of this entity in a third-year-old boy and discuss the physiopathogenesis, the imaging features and the best technical note to manage this cyst in this location.
