A 43-year-old man with no relevant medical history visited an ear, nose, and throat specialist because of deafness in the left ear. He was diagnosed with otosclerosis for which a stapedectomy was performed, resulting in resolution of symptoms. During the diagnostic evaluation, a magnetic resonance image of the brain was performed; based on the findings, he was sent to a neurologist. He had no clear neurological concerns. Findings of neurological examination were unremarkable. His father had died of a heart attack at the age of 45 years. One of his sisters sustained a myocardial infarction at the age of 46 years; the other was diagnosed with cancer and died at age 24 years. His 2 brothers died in early infancy of unknown cause.
