چکیده
neurocutaneous melanosis (ncm) is a rare, congenital non-hereditary syndrome, characterized by multiple pigmented nevi. we report the radiologic findings of a newborn who had extensive cutaneous melanotic nevus with satellite lesions in the brain. ultrasound showed multiple echogenic foci in the cerebral parenchyma. subsequent mri confirmed these lesions as characteristic deposits of melanin. the infant was asymptomatic, but presence of risk factors such as malign transformation or neurological manifestations makes early diagnosis very important. we present this case to emphasize on the radiological findings of this syndrome in order to reach an early diagnosis.
