Carotidynia has been removed from the main classification to the appendix because an extensive literature survey suggests that it is not an entity but a syndrome encompassing many varieties of pain in the carotid region. In particular, carotidynia as described in the first edition of The International Classification of Headache Disorders - neck pain lasting <2 weeks with tenderness to palpation over the carotid bifurcation - can be due to carotid dissection (which should be coded as 6.5.1 Arterial dissection). Some cases have recently been published of carotidynia with MRI abnormalities (described as an intermediate signal on T1W1 and a masked ring enhancement after gadolinium injection) in the tissue surrounding the symptomatic artery. Until the specificity of this finding is established, carotidynia is better considered as a syndrome rather than as a distinct entity.
