A 41-year-old female presented with menorrhagia, fatigue, dyspnea for six months and altered sensorium for the last three days. There was no other history of significance. She was severely pale, drowsy and confused. Hematological examination revealed very low hemoglobin (2.6 mg/dL), packed cell volume 8.8%, mean corpuscular volume 74.7 fL, red cell distribution width 28.5%. Serum iron levels were very low (10 μg/dL) and transferrin saturation was 2.66%. Rest of the detailed blood work-up was unremarkable. Magnetic resonance imaging (MRI) of brain revealed symmetrical hyperintensity in deep periventricular, subcortical white matter in bilateral frontotemporoparietal regions including centrum semiovale and corpus callosum on T2-weighted and FLAIR images with diffusion restriction [Figure 1]. Abdominal sonography revealed uterine fibroids. Following three units of packed cell transfusion and hematinics, there was a dramatic improvement in her sensorium and MRI (done after three weeks) [Figure 2].

Acute toxic leukoencephalopathy is a clinico-radiological syndrome characterized by structural alteration of myelin leading to diffuse white matter dysfunction. The etiology of this uncommon disease can be cranial irradiation, environmental/metabolic toxins, therapeutic drugs, illicit drugs and uremia., To the best of our knowledge, this is the first case of anemia causing acute leukoencephalopathy.
The proposed pathophysiological mechanism can be anemic hypoxia related abnormalities of mitochondrial electron transport chain impairing adenosine triphosphate production resulting in leucotoxicity.
This is of potential clinical importance as lack of awareness may lead to misdiagnosis. Also, we wish to emphasize the prognostic importance of MRI in predicting the clinical outcome.
