title: An uncommon cause of peripheral neuropathy.
abstract: The following case report is of a middle aged man with a progressive neurologic disability who was brought to our emergency department. Caregivers could no longer manage him once he lost the ability to ambulate and became incontinent. At that time his neurologic and hematologic parameters were fairly typical of cobalamin deficiency. We are reporting this case to emphasize that cobalamin deficiency is not always due to pernicious anemia in the elderly or the malnourished alcoholic. Deficiency from uncommon causes can manifest at any age and result in severe morbidity.
