Non-Midline Frontal Encephalocele Presenting as Disappearing Dermoid

: Congenital masses in the lateral brow are most commonly dermoid cysts and can often be excised surgically without additional investigation. These dermoids may rarely develop intracranial extension due to underlying bony erosions and become less prominent over time - a "disappearing dermoid." However, the authors present an unusual alternative case in which an off-midline frontal encephalocele initially presented as a firm irreducible mass but exhibited changing characteristics over time.
