Primary non-essential cutis verticis gyrata revealed with 3-D magnetic resonance imaging.

Sir, Cutis vertices gyrata (CVG) is characterized by thickening of the scalp, which becomes raised to form ridges and furrows resembling the cerebral gyri, which cannot be flattened by traction or pressure. The diagnosis is based on clinical features, and further investigations are needed to demonstrate the precise typical features. We describe how three-dimensional magnetic resonance imaging (3D MRI) can be used to visualize the extent of the lesions in primary non-essential CVG.
