Spontaneous hemorrhage into a lumbar synovial cyst

Marta Cicuendez et al. Eur Spine J. 2010 Jul.

Abstract

Lumbar synovial cysts frequently present with back pain, chronic radiculopathy and/or progressive symptoms of spinal canal compromise. These cysts generally appear in the context of degenerative lumbar spinal disease. Few cases of spontaneous hemorrhage into synovial cysts have been reported in the literature.
