Carotidynia Versus Transient Perivascular Inflammation of the Carotid Artery (TIPIC) Syndrome: Finding Common Ground

Carotidynia remains mired in controversy. Whether to identify this self-limiting unilateral neck pain as a distinct clinical entity or a diagnostic sign associated with a variety of conditions remains a topic of ongoing debate. Adding to the discussion is the occasional finding on imaging studies of a transient inflammatory process surrounding the carotid artery in a number of individuals who present with unilateral neck pain. Although some use carotidynia as the designation of choice by which to identify this inflammatory process, the acronym TIPIC (transient perivascular inflammation of the carotid artery) syndrome is being touted as a far more descriptive and less contentious alternative. Having TIPIC syndrome replace carotidynia, however, need not necessarily signal the latter's outright elimination as some have advocated. When used as a diagnostic sign, carotidynia provides an appreciation of the many conditions that may be associated with idiopathic unilateral neck pain.
