Intracranial meningeal melanocytoma associated with ipsilateral nevus of Ota. Case report

J Neurosurg. 2002 Mar;96(3):619-23. doi: 10.3171/jns.2002.96.3.0619.

Abstract

In this report, the authors review the case of a man with a neurocutaneous syndrome. He presented with an intracerebral melanocytoma associated with a blue nevus of the scalp; its location and its appearance during childhood supported the diagnosis of a nevus of Ota. Meningeal melanocytomas are increasingly being diagnosed, but remain rare. Primary meningeal malignant melanoma is the first differential diagnosis to eliminate. Despite their common embryonic origin. the association of a melanocytoma with a nevus of Ota is rare. A nevus of Ota exhibits the same melanocytic proliferation and affects the trigeminal nerve territory. An ocular effect is not always observed. In contrast to an ocular lesion, a nevus of Ota rarely transforms into a malignant melanoma. It is found only among caucasians. During 4 years of follow-up review after surgery, the patient remained asymptomatic. Other than antiepileptic therapy, he received no complementary treatment and cerebral imaging revealed no evidence of recurrence.
