Since the onset of the COVID-19 pandemic, this condition has been dangerously overlooked and poses an even greater threat when complicated by vascular pathologies. A case is presented where the patient required emergency endovascular exclusion of a right internal carotid artery pseudoaneurysm due to Lemierre syndrome. The treatment included stent graft placement and drainage of a neck abscess, along with appropriate antibiotic treatment during hospitalization. Recognizing this diagnosis requires a high index of suspicion, particularly during the COVID-19 pandemic. The complexity of the disease necessitates extensive multidisciplinary collaboration for effective treatment.
