Cerebriform intradermal nevus manifesting as cutis verticis gyrata

Cutis verticis gyrata (CVG) is a rare scalp condition characterized by scalp skin redundancy that manifests as thickening of scalp skin with furrows and convoluted folds, giving out a cerebriform pattern of external appearance. CVG might manifest either as primary or secondary to an underlying cause. This case demonstrates the typical imaging findings of CVG that was provisionally diagnosed on imaging and confirmed on histopathology as secondary to cerebriform intradermal nevus in a healthy adolescent girl presenting with history of focal irregular scalp thickening since birth.
