A 54-YEAR-OLD WOMAN presented with pulsatile tinnitus in her left ear.
The pulsatile noise was present only when she lowered her head for a long

were unable to see it clearly. Audiometry demonstrated a 15-dB air-bone gap
across the lower frequencies up to 1 kHz in the left ear and a 20-db sensorineural
hearing loss at 6 and 8 kHz in both ears. Discrimination scores were normal
bilaterally. Figure 1 shows a 1-mm-thick
slice of a high-resolution, non–contrast-enhanced computed tomographic
(CT) scan of the middle ears and mastoids. . . . [Full Text of this Article]
