Vitamin B(12) deficiency (B(12)D) has a wide variety of neurological symptoms 
and signs. However, cerebellar dysfunction and cranial neuropathies other than 
optic neuropathy have been rarely reported. Herein, we describe two cases of 
unusual neurological manifestations of B(12)D. One patient showed prominent 
hoarseness with vocal cord paralysis, myelopathy, and peripheral neuropathy. The 
other had gait disturbance, lateral gaze limitation and cerebellar dysfunction 
in addition to the typical manifestations of subacute combined degeneration. 
Vitamin B(12) deficiency can rarely affect cerebellum and cranial nerves other 
than optic nerve.
