Rare Case of Giant Supratentorial Dermoid Cyst

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.

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.

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.
