| Abstract |
|
Low serum vitamin B12 (cobalamin) level is a valuable indicator of cobalamin-deficiency megaloblastic anemia, which sometimes
presents as pancytopenia. It can also be diagnosed by cobalamin deficiency if the patient shows related clinical symptoms and
increased serum homocysteine or urine methylmalonic acid, metabolites of cobalamin, although the serum cobalamin level may be
normal. We report a case of cobalamin-deficiency megaloblastic anemia presenting as pancytopenia with an increased serum vitamin
B12 level. (Korean J Med 77:S1314-S1317, 2009) |
