A case of intrauterine diagnosed posterior fossa dermoid presenting in childhood

Abstract

Intrauterine intracranial brain tumor is a rare entity. Traditionally, the outcome of this tumor had been dismal. In a large series of congenital brain tumor, the commonest have been teratoma followed by astrocytoma and craniopharyngioma. We report a case of intracranial dermoid in post-fossa diagnosed at 8 months of intrauterine life during routine prenatal ultrasonography. The child's clinical picture, the surgery performed and the final outcome have been discussed. As far as our knowledge goes, this is perhaps the first reported case of intrauterine-diagnosed intracranial dermoid.
