Correlating auditory evoked and brainstem histologic abnormalities in infantile Gaucher's disease

In an infant with Gaucher's disease, brainstem auditory evoked responses were abnormal on three separate occasions. Only waves I and II were typically present at standard intensity settings, although a third peak was elicited at 88 dB. Histologic studies demonstrated absence of neurons in the cochlear nuclei and a hypoplastic superior olivary complex. This neurophysiologic-pathologic correlation supports contentions that both brainstem auditory evoked response (BAER) waves I and II arise from the auditory nerve and that it may be capable of generating additional peaks.
