Neurocutaneous melanosis is a rare neurocutaneous syndrome defi ned by the presence of multiple and /or giant congenital cutaneous nevi and melanocytic deposits in the central nervous system with the infi ltration of leptomeninges. The major medical concern with giant congenital cutaneous nevi is high risk of developing cutaneous melanoma, leptomeningeal melanoma, and neurocutaneous melanosis. ...

We describe imaging findings in a 2-year-old girl with neurocutaneous melanosis and malignant cerebral melanoma. Because the cerebral melanoma in this child was of the amelanotic type, high-signal intensity on unenhanced T1-weighted images was not present. The cutaneous lesions played a crucial role in establishing a correct (presumed) histopathologic diagnosis on the basis of the imaging findi...

Sir, We read with great interest the case report by Ahuja et al of a child, 6 weeks old, with multiple giant congenital melanocytic nevi and central nervous system melanosis. Neurocutaneous melanosis has been reported to manifest itself most commonly within the first two years of life and children with this entity have been born as still births or have been reported at as early as one month of ...

Examination of the cerebrospinal fluid showed that there was no infection with Cryptococcus or any other agents, indicating an effective response to the treatment. The combination of clinical and radiological worsening, despite an effective treatment response...

PURPOSE To describe the MR findings of neurocutaneous melanosis in the brain and correlate these with the known pathology and proposed embryologic basis of this disorder. METHODS The brain (seven patients) and spine (three patients) MR scans of seven patients with neurocutaneous melanosis were retrospectively reviewed. In two patients, findings were confirmed at surgery. The pattern of centra...

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. t...
