Abstract

A 52-year-old woman with cystic fibrosis presented to the emergency department with expressive aphasia and right-sided hemiparesis. CT scan of the brain revealed a left middle cerebral artery territory infarct. A diagnosis of cerebral paradoxical embolisation associated with patent foramen ovale and a history of deep venous thrombosis was made. The patient underwent endovascular thrombectomy and percutaneous closure of patent foramen ovale. Current literature, including five published case reports, pertaining to the subject is discussed. The unique aspects of the case are highlighted, including the particular risk of cerebral paradoxical embolisation in patients with cystic fibrosis. The result of this case report, in context to previously reported literature, suggests that clinicians should be aware of paradoxical embolisation in patients with cystic fibrosis via an intracardiac shunt, particularly with implanted vascular access devices and a history of deep venous thrombosis.
