Magnetic resonance and ultrasound imaging of a patient with carotydinia.

Carotydinia, also called transient perivascular inflammation of the carotid artery (TIPIC) is a rare diagnostic entity related to an inflammation over the carotid bifurcation region. Despite the confusion about the definition of this term, neck pain remains the main symptom. Several articles revealed the relevance of imaging in the diagnosis of this disease. We report magnetic resonance and ultrasound images of a case with carotydinia, and also the elements that could eliminate differential diagnoses.
