Parapharyngeal Neck Schwannomas with Unusual Vascular Displacement

Parapharyngeal Neck Schwannomas with Unusual Vascular Displacement

This case report illustrates two unusual cases of parapharyngeal schwannomas mimicking carotid body tumors in terms of characteristic vascular displacement. Carotid body tumors classically cause splaying of internal and external carotid arteries demonstrating the Lyre sign on imaging. Also interest...
