Detection of occult cobalamin deficiency by magnetic resonance imaging.
We present a case of cobalamin deficiency in an elderly woman who presented with peripheral neuropathy without evidence of anemia or macrocytosis; her diagnosis was suspected with cervical magnetic resonance imaging. This imaging modality may identify patients with cobalamin deficiency who have neurologic abnormalities with normal hematologic parameters.
