Macrocytosis and sudden sensorineural hearing loss: a case report

  • A E L McMurran (a1) and R A Adair (a1)

Although other blood dyscrasias are known to cause sudden sensorineural hearing loss, macrocytosis has not previously been implicated in the absence of another causative agent.

Case report:

We present a case of bilateral sequential sudden sensorineural hearing loss in a patient with significant macrocytosis (mean corpuscular volume at presentation 124 fl) secondary to alcohol-induced liver dysfunction.


A possible pathophysiological mechanism linking macrocytosis and sudden sensorineural hearing loss was identified, suggesting areas for further investigation.
