Spinal arachnoid cysts are relatively uncommon lesions, broadly classified as either congenital or acquired. Acquired cysts may develop following trauma, hemorrhage, or post-infectious inflammation. Depending on their location, these cysts can cause a range of symptoms, including quadriplegia, pain, sensory disturbances, and gait impairment. Surgical resection may be indicated in cases with significant neurological symptoms. We report the case of a 77-year-old woman who presented with persistent bilateral leg numbness and pain. Magnetic resonance imaging revealed a suspected intradural spinal arachnoid cyst or arachnoid web at the Th7-8 level, and surgery was planned to relieve the symptoms.
Endo et al. (Thu,) studied this question.
