A 34-year-old woman presented with walking difficulty and pain in the legs 3 years after several abdominal operations for pancreatic cancer and intestinal obstruction thereafter. Corneal erosion, loss of deep sensation in the legs, polyneuropathy, myopathy, and memory disturbance were recognized. Deficiency of multiple vitamins (A, B1, B6, D, E, K) was found. The diagnoses were vitamin A-deficient corneal erosion, vitamin K-deficient bleeding abnormality (asymptomatic), and the neurological deficits caused by vitamin E, B1, B6 and D deficiency. Although the vitamin supplement started 2 years after the onset of the neurological disease, both clinical and electrophysiological recovery was seen. She was unable to walk on admission, but became able to walk after vitamin E supplement. To our knowledge, this is the first report showing multi-vitamin deficiency causing extensive neurological, ophthalmological, and hematological deficits. Recognition of this condition would prevent the progression of potentially irreversible neurological disorders in patients with malabsorption syndrome after extensive abdominal surgery.
