Background
There are many lesions that can cause compression of nerves and vessels of the head and neck, and many of these can be overlooked if not suspected by the radiologist or proper symptoms are not given in the history. Patients may not have symptoms in the neutral position, but may be brought on by certain positions; therefore, it is important to perform imaging with the patient in the specific position that causes the symptoms, or the lesion may be missed.

Educational Goals / Teaching Points
This educational exhibit will discuss the typical and atypical compressive lesions of the head and neck using a case-based approach and multimodality imaging. Our objective to discuss these typical and atypical compressive lesions of the head and neck as outlined below:

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Key pathologies: 1. Vascular Compression: a. Trigeminal Neuralgia b. Glossopharyngeal Neuralgia c. Hemifacial Spasm d. Trochlear Nerve Palsy e. Abducens Nerve Palsy f. Medulla Compression 2. Osseous Compression: a. Cervical Rib b. Bow Hunter’s Syndrome c. Golfer’s Stroke—variants? (elongated lesser cornua) 3. Miscellaneous: a. Herniated gyrus rectus

Conclusion
High index of suspicion and optimal positioning for imaging is key in patients with compressive lesions of the head and neck.
