Assistant Professor, Department of Radiology, Division of Neuroradiology, Amiralam Hospital, Tehran University of Medical Sciences



Carotid space extends from carotid canal and jugular foramen at skull space down to aortic arch.
It contains internal carotid artery, internal jugular vein, cranial nerves 9-12 & sympathetic plexus. Common lesions of carotid space include mainly paraganglioma, nerve sheath tumors, lymph nodes and vascular lesions such as carotid artery aneurysm and dissection as well as jugular vein thrombosis. Different interactive cases of carotid space lesions as well as clues for differentiating them from parapharyngeal space lesions will be presented with details during the session.
