Spinoglenoid notch syndrome

Spinoglenoid notch syndrome is due compression of suprascapular nerve, due to a cyst, at the spinoglenoid notch causing pain, which is often mistaken for rotator cuff injury or cervical spondylosis. This patient presented with pain on the back of the right shoulder with weakness of external rotation and abduction. On examination, he had wasting, and weakness of the infraspinatus muscle and rest of the neurological examination was normal. His right shoulder magnetic resonance imaging scan revealed a cystic lesion at the spinoglenoid notch. An ultrasound guided aspiration of the cyst was done. He improved well with physiotherapy. One year later, the bulk and power of his infraspinatus muscle was normal.
