Juvenile distal muscular atrophy of the upper extremity, also known as Hirayama’s disease (HD), is a rare muscular atrophy disease, predominantly in the male. The lesion is primarily located in the anterior horn of the lower cervical spinal cord. It is typically characterized with the forearm ulnar muscular atrophy and the affected upper limb showing slope-like changes. The disease progresses slowly with self-limitating feature. In this article, two HD cases were reported, who were admitted to our hospital due to chief complaint of the weakness of the right hand and upper limb. MRI of the cervical spine in a hyperflexion position showed the widening of epidural space and the thickening and advancing of dura mater. Electromyography revealed the neurogenic injury of the right upper limb. Both patients were restored and discharged after neck brace treatment and oral vitamin B. Two patients remained physically stable during 5-year follow-up. The diagnosis of HD mainly depends upon clinical manifestations, imaging examination and electromyography. MRI of the cervical spine in a hyperflexion position is the most common auxiliary examination. Clinicians should improve their understanding of HD and reduce the misdiagnosis rate.
