Vietnamese Case Series of Hirayama Disease.

BACKGROUND/AIM: Hirayama disease, a rare neurological disorder, is characterized by progressive, asymmetric muscle atrophy of the forearm and hand in young male patients.

CASE REPORT: We noted two cases of Hirayama disease that appeared in the right upper limb and identified the cervical neutral and flexion position magnetic resonance imaging (MRI) characteristics.

CONCLUSION

In the flexion posture, the cervical MRI allows early diagnosis of Hirayama disease and should be considered in patients with the typical clinical symptoms.
