Cobb syndrome is the presence of a spinal arteriovenous malformation and a vascular skin lesion, e.g. port wine stain, affecting the corresponding dermatome.


Cutaneous lesions that have been reported include angiomas, angiokeratomas, angiolipomas, and lymphangioma circumscriptum.

The intraspinal lesions are usually AVMs and rarely angiomas. Neurologic symptoms develop most commonly in late childhood, but may occur at any age. They may present with sudden onset of weakness with rapid progression, monoparesis or sudden-onset paraplegia or quadriplegia. Bladder and bowel involvement is common but tends to occur late.
