Spinal arachnoid cysts are unusual distinct pouches of cerebrospinal fluid (CSF) or CSF-like fluid discovered adjoining to regular CSF areas generally extradural and barely intradural. They’re normally asymptomatic and found by the way. We current a affected person with fast higher motor neuron neurologic deterioration over the course of 1 week. Findings on magnetic resonance imaging revealed numerous central nervous system demyelination lesions and thoracic arachnoid cyst with twine compression. This acute presentation, within the absence of trauma, just isn’t in favor of the pure historical past of the intradural thoracic arachnoid cysts. The affected person’s sensory, gait, and decrease limb neurologic deficits improved after surgical procedure with residual delicate however steady higher limb deficits. Our affected person probably had a static compensated cyst made symptomatic by demyelination as an extra central nervous system lesion.
