JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 151 OP 152 DO 10.1136/jcp.34.2.151 VO 34 IS 2 A1 Anderson, C G A1 Walton, K R A1 Chanarin, I YR 1981 UL http://jcp.bmj.com/content/34/2/151.abstract AB A 71-year-old woman was treated with radiotherapy for carcinoma of the cervix. Nine year later she was found at laparotomy to have a thickened narrow ileum. At the time she had an iron-deficiency anaemia and when this was treated the blood picture changed to that of a severe megaloblastic anaemia. This was due to cobalamin deficiency resulting from malabsorption of cobalamin by the damaged ileum.
