Abstract

BackgroundCanavan disease is an autosomal recessive disorder with spongy degeneration of white matter of the brain. It presents with developmental delay, visual problems and macrocephaly. Patient descriptionWe report a ten-month old boy with Canavan disease who presented with global developmental delay, seizures, abnormal eye movements and microcephaly. ResultsMRI brain revealed diffuse involvement of the supra tentorial white matter, globus pallidi, thalami, dentate nuclei and brainstem with sparing of the corpus callosum. The genetic testing revealed homozygous mutation of aspartoacylase gene [c.859 G>A (p.Ala287Thr)] in Exon 6. ConclusionPossibility of Canavan disease should be considered even in the presence of microcephaly.
