ANSWERS AND EXPLANATIONS




A) Riboflavin

This answer is incorrect.


This FLAIR MRI shows hyperintensity in the medial thalamic nuclei. This finding is characteristic of both Wernicke encephalopathy and Korsakoff dementia, which are both due to a deficiency of thiamine (vitamin B1).

Vitamin B2 (Riboflavin) deficiency does not typically produce the lesions shown. Ariboflavinosis is associated with mouth and tongue inflammation, and has been associated with personality changes.

C) Vitamin E

This answer is incorrect.


This FLAIR MRI shows hyperintensity in the medial thalamic nuclei. This finding is characteristic of both Wernicke encephalopathy and Korsakoff dementia, which are both due to a deficiency of thiamine (vitamin B1).

Vitamin E deficiency does not typically produce the lesions shown. Vitamin E deficiency leads to axonal degeneration of large, myelinated axons, leading to loss of axons in the posterior column and spinocerebellar tracts, and to peripheral neuropathy.

E) Vitamin B12

This answer is incorrect.


This FLAIR MRI shows hyperintensity in the medial thalamic nuclei. This finding is characteristic of both Wernicke encephalopathy and Korsakoff dementia, which are both due to a deficiency of thiamine (vitamin B1).

Vitamin B12 (Cyanocobalamin) deficiency does not typically produce the lesions shown. Cyanocobalamin deficiency leads to pernicious anemia and many neurologic problems: peripheral neuropathy, subacute combined degeneration of the spinal cord, psychosis, depression, dementia, and optic neuropathy.
