RESUMEN

CONTEXT: Decreased vitamin B12 concentration does not usually result in clinical or hematological abnormalities. Subacute combined spinal cord degeneration and pancytopenia are two serious and rarely displayed consequences that appear in severe deficits. CASE REPORT: We present the case of a patient with subacute combined spinal cord degeneration and pancytopenia secondary to severe and sustained vitamin B12 deficiency. Such cases are rare nowadays and have potentially fatal consequences. CONCLUSIONS: Vitamin B12 deficiency should be taken into consideration in the differential diagnosis in cases of blood disorders or severe neurological symptoms. Early diagnosis and treatment can avoid irreversible consequences.


CONTEXTO: El descenso de la concentración de vitamina B12 no suele derivar en alteraciones clínicas o hematológicas. La degeneración combinada subaguda medular y la pancitopenia son dos consecuencias graves y poco frecuentes que aparecen en los déficit severos. CASO CLÍNICO: Presentamos el caso de un paciente con una degeneración combinada subaguda medular y pancitopenia secundarios a un déficit severo y mantenido de vitamina B12. Un caso poco común en nuestros días y con consecuencias potencialmente fatales. CONCLUSIONES: Debemos considerar el déficit de vitamina B12 dentro del diagnóstico diferencial en caso de alteraciones hematológicas o síntomas neurológicos graves. Su diagnóstico y tratamento precoz pueden evitar secuelas irreversibles.

RESUMEN

Vitamin B12 deficiency may cause hematologic, gastrointestinal, psychiatric and neurological symptoms. Sub-acute combined degeneration of spinal cord, which develops in the deficiency of vitamin B12, may be reversible in case of early diagnosis and treatment. We describe the management of a 50-years old female who got admitted with pancytopenia and elevated LDH, with walking difficulties since last 15 days. B12 and folic acid levels were found in normal ranges. Megaloblastic changes were observed in the bone marrow examination. Abnormal hyperintence signal changes were observed in T2-weighed cervical spinal cord Magnetic Resonance Imaging in posterior row. Due to the high homocysteine level, treatment with parenteral B12 vitamin was initiated. Following the 3-months treatment, hematologic counts and neurological symptoms of the patient were found to be completely recovered at the control visit. Vitamin B12 deficiency should be considered for the patients with pancytopenia, elevated LDH levels and neurological symptoms, even if vitamin B12 and MCV levels are in normal ranges. Vitamin B12 deficiency should be confirmed with the additional assays, such as, the assessment of serum homocysteine and methylmalonic acid levels, and the treatment should be started promptly
