Spinal cord atrophy following the resection of multiple intraspinal arachnoid cysts: case report and literature review.

We report the first case of spinal cord atrophy developing 16 months after resection of multiple intraspinal arachnoid cysts. The patient presented with back pain and the cysts were successfully resected. Sixteen months later, her back pain recurred. Magnetic resonance imaging showed severe atrophy of the spinal cord.
