Cobb's syndrome, or cutaneomeningospinal angiomatosis, is a combination of the vascular skin nevus and angioma in the spinal cord within a corresponding segment or two to the dermatoms involved.

A 15 year old girl showed the portwine nevus at T2-T11 dermatomes and multilevel spinal angioma at C7-L3 levels. She had suffered from a slowly progressive weakness of both lower extremities. Motor weakness of lower extremities improved after the combined rehabilitation management and radiation therapy for 4 months. We report the typical manifestations of Cobb's syndrome in a 15 year old girl with the brief review of literatures.
