Materials and methods. Six patients with clinically suspected Hirayama disease were scanned on 3 Tesla MRI with neutral position, flexion, contrast-enhanced MRI and diffusion tensor imaging. Results. MRI findings of localized cervical cord atrophy at C5-C7 level, abnormal curvature, asymmetric cord flattening, loss of attachment of the dorsal dural sac and subja-cent laminae in the neutral position, anterior displacement of the dorsal dura on flexion, сontrast enhancement of the epidural component and a prominent epidural space were re-vealed. Also, MRI studies were complemented by diffusion tensor sequence with the definition of the course and structure of the conductive pathways of the spinal cord. Conclusion. MRI study of the cervical spine with flexion should be an integral part of the diagnostic protocol for suspected Hirayama disease.

 

Keywords: flexion MR, Hirayama disease, spinal cord DTI.
