Rare Case of Giant Supratentorial Dermoid Cyst

Abstract

Background: Dermoid cysts are benign, congenital rare lesions, frequently occurring in or near the midline. Rare localizations and variable radiologic findings have been described but remain exceptional.

Case description: The authors present a rare case of a giant temporoparietal dermoid cyst in an adult female who was paucisymptomatic. No sign of rupture was identified, with a clinical presentation suggesting a slow-growing lesion. Gross total excision was performed with a favorable clinical and radiologic outcome.

Conclusions: Rare localizations previously published in the literature are discussed for dermoid cysts. To our best knowledge, this is the first giant dermoid cyst presenting with this localization.
