In imaging studies, this neoplasm may be confused with other neck neoplasms such as thyroid carcinoma. The purpose of this retrospective, cross\u2010sectional study was to describe computed tomographic (CT) and magnetic resonance imaging (MRI) characteristics of confirmed carotid body tumors in a multi\u2010institutional sample of dogs. A total of 16 dogs met inclusion criteria (14 examined using CT and two with MRI). The most common reason for imaging was a palpable cervical mass or respiratory signs (i.e., dyspnea or increased respiratory noises). The most commonly affected breed was Boston terrier (<jats:italic>n<\/jats:italic>= 5). Dogs were predominantly male castrated (<jats:italic>n<\/jats:italic>= 10) and the median age was 9 years [range 3\u201314.5]. Most tumors appeared as a large mass centered at the carotid bifurcation, with poor margination in six dogs and discrete margins in ten dogs. Masses were iso\u2010 to hypoattenuating to adjacent muscles in CT images and hyperintense to muscles in T1\u2010 and T2\u2010weighted MRI. For both CT and MRI, masses typically showed strong and heterogeneous contrast enhancement. There was invasion into the adjacent structures in 9\/16 dogs. In six of these nine dogs, the basilar portion of the skull was affected. The external carotid artery was entrapped in seven dogs. There was invasion into the internal jugular vein in three dogs, and into the external jugular, maxillary, and linguo\u2010facial veins in one dog. Imaging characteristics helped explain some clinical presentations such as breathing difficulties, Horner's syndrome, head tilt, or facial nerve paralysis.<\/jats:p>","DOI":"10.1111\/vru.12254","type":"journal-article","created":{"date-parts":[[2015,4,6]],"date-time":"2015-04-06T01:06:56Z","timestamp":1428282416000},"page":"374-383","source":"Crossref","is-referenced-by-count":20,"title":["CT AND MRI FEATURES OF CAROTID BODY PARAGANGLIOMAS IN 16 DOGS"],"prefix":"10.1111","volume":"56","author":[{"given":"Wilfried","family":"Mai","sequence":"first","affiliation":[{"name":"Department of Clinical Studies, Section of Radiology, University of Pennsylvania School of Veterinary Medicine Philadelphia PA 19104"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriela S.","family":"Seiler","sequence":"additional","affiliation":[{"name":"Department of Molecular Biomedical Sciences, North Carolina State University College of Veterinary Medicine Raleigh NC 27607"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Britany J.","family":"Lindl\u2010bylicki","sequence":"additional","affiliation":[{"name":"William H.
