Although endothelial damage has been hypothesized to be associated with coronavirus disease 2019 (COVID-19)-related cerebral infarction based on the specificity of the viral cellular invasion pathway, no case has been reported to date. We herein report a 51-year-old Japanese woman who presented with neck pain one week after COVID-19 infection. Computed tomography and magnetic resonance imaging revealed inflammation of the carotid and vertebral arteries. Ultrasonography revealed multiple flap-like structures that were assumed to be thrombi. Although the patient had no cerebral infarction, this could be an important case of vascular damage and thrombus formation in a COVID-19 patient.

Transient Perivascular Inflammation of Carotid artery syndrome (TIPIC syndrome) is a non-specific inflammatory thickening of the carotid artery. The exact etiology of this syndrome is poorly understood. We will describe the radiological findings of a rare case of TIPIC syndrome in a patient with myelodysplastic syndrome and discuss the potential pathophysiological mechanisms.
