1. Neurogenic thoracic outlet syndrome (TOS) comprises the vast majority of TOS cases. 2. In addition to clinical features, high resolution MRI and MR neurography of the brachial plexus can be useful in rendering the diagnosis. 3. Percutaneous procedures performed under sonography, CT and MRI guidance can aid in both the diagnosis and treatment of neurogenic thoracic outlet syndrome.  

Predisposing and Causative Factors - Normal anatomy - Trauma - Anatomic variations predisposing to TOS (cervical ribs, anomalies of the costoclavicular & retropectoral space) Clinical Evaluation - History and physical examination (Adson’s test) - Electrodiagnostic studies Imaging and Image-Guided Diagnosis - MR neurography technique and findings - Scalene muscle injections: Principles - Scalene muscle injections: Techniques and pitfalls with MRI, CT, and Ultrasound guidance - Pectoralis minor injections Treatment - Surgical indications and therapy (scalene excision vs. first rib resection with scalenotomy) - Image guided botulinum toxin injection: Principles and techniques
