Introduction And Importance:
Hirayama disease is a rare benign motor neuron disorder that involves a single upper limb. It affects the lower cervical myotomes and presents clinically by muscle wasting and weakness.
Case Presentation:
We report the case of a 17-year-old female who presented with a four weeks history of progressive weakness of the left upper limb. The blood investigations and image reported unremarkable findings. Patient improved on physiotherapy.
Clinical Discussion:
Hirayama disease is rarely encountered in clinical settings and should be suspected in female patients presenting with unilateral or asymmetrical bilateral lower motor weakness of hands and forearms.
Conclusion:
We present a rare condition in a 17-year-old female with a left upper extremity monomelic amyotrophy, a Hirayama disease.
