Imaging findings of vitamin deficiencies: are they forgotten diseases?

Abstract

Vitamin deficiency is rare in modern industrialised countries; however, it still occurs in patients with specific backgrounds, such as those with extremely unbalanced diets, those with alcoholism and those who have undergone gastrointestinal surgery. Imaging examinations that demonstrate classic findings confirm the clinical diagnosis of vitamin deficiency and help monitor response to treatment. Because vitamin deficiencies are not prevalent, the diagnosis might not be straightforward. Therefore, imaging should be performed in cases of suspected vitamin deficiency. Radiologists should be familiar with characteristic imaging findings of vitamin deficiency and should survey an affected patient’s background and blood vitamin levels. Because symptoms of vitamin deficiency are quickly improved by vitamin replacement, early diagnosis is essential. This pictorial review provides imaging findings for deficiencies in vitamins B1 (Wernicke encephalopathy and wet beriberi), B12 (subacute combined degeneration), C (scurvy), D (rickets) and K (bleeding tendency).

Should Clinicians Prescribe Non-FDA Regulated Dietary Supplements When Caring for Children With Hypovitaminosis D?

“…Vitamin D deficiency is associated with metabolic bone diseases such as rickets and osteomalacia, signs and symptoms of which include delayed growth, delayed acquisition of motor skills, bony pain, and muscular weakness. 11 Vitamin D has additional roles in many organ systems, and hypovitaminosis D increases risk of many diseases. 12 The achievement of nutritional sufficiency in patients with SBS through enteral supplementation is challenging due to malabsorption, decreased intestinal mass, and incomplete or absent coverage of supplementation costs.…”
