PATHOLOGIC QUIZ CASE 1
ROBERT I. KOHUT, MD, CHICAGO
On awakening one morning a 65-year-old woman, in apparent good health, experienced severe vertigo and some vomiting. The vertigo improved slowly, but a sense of discomfort persisted in the right ear for about one month. There was no tinnitus or subjective loss of hearing.An examination of the ears, nose, and throat four weeks following the onset of the vertigo showed the tympanic membranes to be normal. An audiogram revealed a bilateral high tone loss, 10 db greater in the right than in the left ear. A spontaneous horizontal nystagmus to the left in all positions of gaze (Frenzel glasses) was present. On postural testing, vertigo was reproduced in the lateral right position and on sitting up from the recumbent position. The nystagmus increased in intensity with the recurrence of vertigo but did not change direction. Irrigation of the right ear
