The carotid body tumor
A 63-year old female was referred to our hospital because she had a mass on the right side of the neck. The swelling had slowly progressed in a couple of months. Besides problems with swallowing there were no other complaints. Her previous medical history was unremarkable and she could not remember any family members with similar lesions. Physical examination showed a non-tender mass with a diameter of around 6 cm located just anterior of the sternocleidomastoid muscle in the anterior triangle of the neck. The mass was mobile in a back-forward direction but could not be moved in a cranial-caudal direction. No signs of cranial nerve deficits were detected. An ultrasound examination showed a highly vascularized structure in the bifurcation between the internal and external carotid artery (Fig. 33.1).
