ABSTRACT: Intracranial dermoid cysts
are congenital benign neoplasms mostly diagnosed in the pediatrichood 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.
