Cervical magnetic resonance imaging (MRI) and right median somatosensory evoked potentials (SEP) of the patient. The T2 weighted MRI with neck in neutral position was unremarkable while T2 weighted MRI with neck in flexion shows anterior displacement of the posterior dural sac (A, B). The reversible inter-peak latency between N13 and N19 on supine (5.5 ms) (C) and flexed (7.45 ms) (D) somatosensory evoked potentials (SEP) in the symptomatic side also support the diagnosis of Hirayama disease. (Normal SEP interpeak latency < 6.59 ms).
