Question of the Week # 308

308)  A 76-year-old man presented with a 4-month history of recurrent vertigo. He reports feeling a sensation of spinning dizziness on turning the neck to his left. He also reports left sided headaches and decreased hearing on the left. Each episode lasted about 15 to 20 minutes and occurred when he turned his head to the left. He denies any ringing sensation in ears,  nausea or vomiting. He denies any chest-pain, shortness of breath or palpitations.  His past medical history is significant for hypertension and diet controlled diabetes. His medications include  hydrochlorothiazide and enalapril. He also has history chronic neck pain due to cervical spondylosis for which he uses tylenol. On examination, his blood pressure in supine position is 140/88 mmHg and  blood pressure on standing is is 130/86. Tympanic membranes are visible and there is some cerumen in the left ear. Using a 512Hz tuning fork , bone conduction is found to be better than air conduction on the left and Weber test shows lateralization to the left. Dix-Hallpike’s and Lhermitte’s signs are negative. There are no other neurological deficits. Gait is normal. Range of motion of the neck is limited on lateral movements and neck pain is elicited by turning to left side. An X-ray of cervical spine shows severe spondylosis with discopathy and osteophytes from C2 to C4 vertebrae.  Which of the following is the most likely explanation for his Vertigo?

A) Orthostatic Hypotension

B) Vertebral artery occlusion from cervical spondylosis

C) Cerumen Impaction

  5. B….Rotational vertebral artery occlusion due to cervical spondylosis.

  6. C BC>AC on the left by Rinne and Weber lacteralized to the left indicates conductive hearing loss on the left.

  7. Oops, I am wrong. It should be B. Compressive osteophytes caused by cervical spondylosis can lead to conductive hearing loss.
