Quadrilateral space syndrome: a case report

Quadrilateral space syndrome is a rare entity caused by isolated compression of the axillary nerve in the quadrilateral space. A twenty-seven-year-old male patient presented with a poorly localized shoulder pain and point tenderness on the posterior aspect of the shoulder. Magnetic resonance imaging showed a fibrous band causing quadrilateral space syndrome. Surgical excision of the fibrous band was performed and the axillary nerve was released. The patient became symptom-free after surgical decompression.
