RESUMO
BACKGROUND: Vitamin B12 deficiency is thought to be uncommon in the eastern parts of India including Bengal and the eastern states as compared to the northern and southern parts of India. The importance of cutaneous features in relation to vitamin B12 deficiency is not well described in literature. AIM: To know the clinical profile of vitamin B12 deficiency in this region and to find out if there is any relationship between dermatologic manifestations with vitamin B12 deficiency. MATERIALS AND METHODS: All symptomatic patients of anemia requiring blood transfusions who had either raised mean corpuscular volume (MCV) or bicytopenia/pancytopenia on complete blood count or were symptomatic in the form of skin hyperpigmentation were screened for vitamin B12 deficiency. RESULTS: Twenty-five patients were tested for vitamin B12 deficiency. Of them 19 patients were found to be having vitamin B12 deficiency. CONCLUSIONS: Vitamin B12 deficiency is not uncommon in the eastern parts of India, contrasting the previous thoughts that it was uncommon in this area, though larger studies are required to know it better. This study included only those requiring blood transfusions, thus a much higher prevalence is expected in this area. Patients with vitamin B12 deficiency do present with severe anemia requiring blood transfusions and often have skin hyperpigmentation.
RESUMO
Transient hyperintensity in splenium of corpus callosum is a relatively infrequent finding in MRI. Although it has been most consistently linked with frequent seizure episodes, many other possible causes have been proposed by different workers. Cryptococcal meningitis as a cause of transient splenial hyperintensity has never been reported till date. Here, we report a young girl who is congenitally immunodeficient and had suffered from cryptococcal meningitis with typical transient splenial hyperintense lesions in MRI.
