Contrasting radiological presentation of cervical sympathetic chain schwannoma: Case series of two cases
Journal Title: Otolaryngologia Polska - Year 2014, Vol 68, Issue 5
Abstract
Splaying of carotid bifurcation on imaging, known as Lyre sign, is seen characteristically in carotid body tumors. Is positive Lyre sign always confi rmatory of carotid body tumor? Here we discuss two cases of cervical sympathetic chain schw annoma. The first case presented radiologically as an enhancing lesion with splaying of external carotid artery and internal carotid artery (positive Lyre sign) and misled us to the diagnosis of carotid body tumor. The second case presented as an enhancing lesion cau sing anterior displacement of external carotid artery and interna l carotid artery (negative Lyre sign). Both lesions were confirmed as cervical sympathetic schwannoma. Post-operatively both patients develo ped Horner's syndrome. Lyre sign is not always confirmatory of carotid body tumor.
