Quadrilateral space syndrome is a scarce condition with symptoms cause by axillary nerve compression within the quadrilateral space. The quadrilateral space lies inferoposteriorly to the glenohumeral joint next to boundaries formed by the teres minor muscle (superiorly), the teres major muscle (inferiorly), the humerus (laterally), and the long pave the way of triceps (medially). The space contains fat, the axillary guts, and the posterior humeral circumflex artery.
The radiologist can suggest the diagnosis on the basis of the finding of teres minor atrophy or extraordinary signal, but needs to evaluate the remainder of the shoulder because other abnormality are usually seen contained by most patients. Injuries of the axillary nerve, brachial plexus, or fortitude roots must also be considered (which may not be included/vsualized on exam) in any patient next to muscle atrophy or neurogenic edema without a distinct cause.
Treatment is usually surgical, involving the lysis of fibrous band within the quadrilateral space.
