Introduction: The clinico-etiological spectrum of Acute leukoencephalopathy with restricted diffusion (ALERD) is not well known in Indian population. This is likely to vary between populations and ethnicities.

Methods: We retrospectively reviewed the clinicoetiological spectrum of ALERD at a tertiary care pediatric center, and described the clinical, imaging, etiological spectrum and short-term outcomes.

Results: Eleven out of 78 children with non-traumatic encephalopathy presenting to our center had a final diagnosis of ALERD. The mean age at presentation was 34.9 months (6-80 months) and 63.6% were males. The monophasic course (72.7%) and the diffuse pattern (63.6%) on neuroimaging were predominant in these children. Dengue haemorrhagic fever was the commonest underlying/triggering infection (5 of 11 children). Ten children required mechanical ventilation in view of neurogenic respiratory failure, with mean duration of ventilation of 6.4 days (Range 2-10 days). The duration of hospital stay varied from 11 to 25 days (Mean - 15.3 days). One child (9 %) died, 6 children (54.5 %) had varying degrees of cognitive impairment and 4 (36.3 %) children had a normal outcome. Children with a shorter duration of ventilation seemed to have a better outcome.

Conclusion: Dengue haemorrhagic fever was the commonest cause, and diffuse imaging pattern with monophasic course was the commonest presentation in Indian children with ALERD. The clinical presentation and factors influencing outcome are possibly different from previously described literature.
