A case of neurocutaneous melanosis and neuroimaging findings.

Abstract

Neurocutaneous melanosis is a rare congenital disorder which presents with congenital cutaneous nevi and involvement of the central nervous system. We herein present a rare case of a 2-year-old girl who had central nervous system melanosis and giant congenital melanocytic nevi. Magnetic resonance imaging, especially precontrast T1 images play a crucial role in making the diagnosis combined with the skin findings of physical examination.
