The Man Who Mistook a Hat for His Wife: Case Report of Aortic Dissection Presenting With Acute Hyperfamiliarity for Faces

Abstract

Acute aortic dissection is a challenging diagnosis for emergency physicians because of its high mortality and wide range of clinical presentations. We report a case of a previously healthy man who presented with hyperfamiliarity for faces syndrome as the predominant symptom of a large type A aortic dissection diagnosed by computed tomography angiography in the emergency department. Different elements of his presentation suggested possible other diagnoses, including transient global amnesia and transient ischemic attack. We discuss how evaluating these other diagnostic possibilities led to the correct diagnosis. Given increasing reports of painless aortic dissection, this case demonstrates the need to consider aortic dissection in patients with acute neurological symptoms.
