[Lateral neck paraganglioma: diagnostic imaging and preoperative embolization].
Sixteen paragangliomas of the neck were reviewed. Lesions were found in the carotid body (n = 12), vagal nerve (n = 3) and larynx (n = 1). While paragangliomas were often misdiagnosed clinically, CT scanning defined the extent of the disease. MR was able to accurately characterize the tumors as highly vascular. Multiplanar imaging, exquisite tissue contrast and anatomic detail allowed better display of the relationship between these neoplasms and surrounding carotid sheath vessels and intracranial structures. MR constitutes the imaging modality of choice in carotid body tumor. Arteriography is necessary for definite diagnosis and presurgical embolization.
