A 17-year-old male, who gave up his favorite sport cricket and started playing football, presented with one-year history of slowly progressive atrophic weakness of forearms and hands. Neurological examination showed weak and wasted arms, forearms and hand but no evidence of pyramidal tract, spinothalmic tract and posterior column lesions. Plain cervical spine radiographs showed no abnormal findings. Cervical magnetic resonance imaging (MRI) showed asymmetric cord atrophy; images obtained with neck flexed showed the anterior shifting of the posterior wall of the lower cervical dural sac resulting in cord compression. These findings suggest Hirayama disease, a kind of cervical myelopathy related to the flexion movements of the neck.
一名17岁男性，放弃了他最喜欢的板球运动，开始踢足球，出现了前臂和手部缓慢进行性萎缩性无力的一年病史。神经系统检查显示手臂、前臂和手部无力且萎缩，但无锥体束、脊髓丘脑束和后柱病变的证据。颈椎X线平片未见异常。颈椎磁共振成像（MRI）显示脊髓不对称萎缩；颈部屈曲时获得的图像显示下颈椎硬膜囊后壁向前移位，导致脊髓受压。这些发现提示平山病，一种与颈部屈曲运动相关的颈椎病。
