Abstract

Background: Carotidynia, also known as Fay Syndrome, manifests as an atypical facial neuralgia characterized by an unusual neck pain extending towards the head and associated with carotid artery tenderness. Diagnostic criteria include neck tenderness, elevated carotid pulse without anatomical abnormalities, and neck distension. It was initially classified as a vascular headache but later re-evaluated and reclassified as a nonentity—a general condition caused by nonvascular factors. The etiology has not been extensively elucidated. Case Presentation: We present two cases characterized by dysphagia, intermittent discomfort, and numbness in the throat and cervical region. Although the neurological examinations yielded no abnormalities, the diagnosis of carotidynia was ultimately established among the differential diagnoses upon the identification of wall thickening and inflammatory alterations through neuroimaging. Conclusions: Carotidynia is consistent with idiopathic vasculitis near the distal common carotid artery. Inflammatory processes trigger sympathetic plexus stimulation, causing discomfort in the head and neck. Neuroimaging resolves ambiguities in idiopathic unilateral neck pain, detecting soft tissue growth near the carotid artery. “Carotidynia” now refers to a diagnostic symptom and clinical entity encompassing a variety of disorders; therefore, approach to definition remains controversial. This report aims to raise healthcare awareness by highlighting two different cases of carotidynia.
