Abstract

Segmental non-progressive spinal muscular atrophy of the upper extremity, also known as Hirayama disease (HD), is a disorder seen mainly in young male patients of Asian ancestry. On MRI loss-of-attachment between the posterior dural sac and adjacent lamina has been described as the only significantly important predictor of HD. We herein present a patient with HD who showed an atypical anterior detachment of the dura mater from the adjacent vertebral body.
