Progressive cystic degeneration of the spinal cord following spinal cord injury.

From a group of 520 spinal cord injury patients treated at Rancho Los Amigos Hospital, two cases of progressive myelopathy secondary to cystic degeneration of the spinal cord have been identified. The cyst may dissect proximately to produce progressive neurologic deficit. Surgical treatment with shunting can allow stabilization and improvement with return of newly lost function.
