Carotidynia: A Rare Diagnosis for Unilateral Neck Pain Revealed by Cross-Sectional Imaging

Abstract EN

Idiopathic carotidynia (IC) is a rare and poorly understood syndrome consisting of unilateral neck pain, tenderness, and increased pulsations over the affected carotid bifurcation.

A growing body of evidence supports the hypothesis that IC is a distinct clinicopathologic entity with characteristic imaging features.

We report the case of a 34-year-old Caucasian male presenting with intense unilateral neck pain in the emergency setting.

Computed tomography and ultrasonography revealed fusiform eccentric thickening of the ipsilateral carotid bifurcation without vessel narrowing.

Contrast-enhanced magnetic resonance imaging depicted major perivascular enhancement without evidence of dissection.

Further imaging and laboratory work-up excluded vasculitis.

The diagnosis of IC was made.

The patient was treated with nonsteroidal anti-inflammatory drugs and symptoms and imaging findings disappeared within a few weeks.

Cross-sectional imaging allows not only ruling out IC mimickers but also making the correct diagnosis of this rare condition, in particular, as the clinical presentation of IC is often nonspecific.
