Combined degeneration of the spinal cord due to deficiency of alimentary vitamin B12

syndromes, anaemia and combined degeneration of the spinal cord. Vitamin B12 deficiency generally results from interstitial gastritis in which intrinsic factor, required for the absorption of vitamin B12, is lacking and when it is caused by inadequate or insuffiicient nutrition macrocytic anaemia is often present but the deficiency seldom assumes such a serious form as combined degeneration of the spinal cord. Indeed we were unable to find in the literature a single well-documented case ofcombined degenera-tion of the cord due to alimentary vitamin B12 deficiency. The publication of a case which has been investigated both clinically and anatomically therefore appears to be warranted. CASE REPOR
