Carotid contrast-enhanced ultrasonography and multimodal imaging in a case of TIPIC syndrome.

Transient perivascular inflammation of the carotid artery (TIPIC) syndrome, previously referred to as 'carotidynia', is an unclassified clinicoradiological entity associating atypical acute neck pain, eccentric perivascular infiltration on imaging and improvement of symptoms either spontaneously or with anti-inflammatory treatment. This case report presents a patient with TIPIC syndrome who underwent five different types of imaging modality, including contrast-enhanced ultrasonography (CEUS) of the carotids, and describes the CEUS appearances of TIPIC syndrome.
