Sudden Onset and Unremitting Vertigo in a Middle-aged Woman

Abstract

A 51-year-old woman presented with a 24-hour history of severe dizziness that she described as "room spinning," right aural fullness, and a subjective right-sided hearing loss. She denied any medical history of vertigo, recent upper respiratory infection, head trauma, or prior otologic surgery.A physical examination revealed no abnormalities on otoscopic evaluation; however, a strongly positive right-sided Dix−Hallpike test was elicited with rotary nystagmus; a subsequent Epley maneuver was performed. The patient's symptoms subjectively worsened during the following several days. Therefore, an audiogram test (Figure 1) and computed tomography (CT) of the temporal bone were performed.
