Background:
Extradural spinal arachnoid cysts (SACs) rarely cause neural compression and disability.
Case description:
A 38-year-old female presented with a history of two episodes of falling due to transient weakness in the lower limbs. The neurological examination showed normal motor and sensory function, but hyperreflexia. The thoracic magnetic resonance imaging revealed multiple extradural SACs between the T3-L1 levels. Following complete surgical resection of the most symptomatic cyst, she did well. The histopathological examination confirmed a Type I extradural SAC.
Conclusion:
Here, we discussed one case and reviewed the literature on the diagnosis and treatment of multiple extradural SACs.
