Sir,

It was nice to read the article by L Elijovich and others, titled 'Hyperdense lenticulostriate artery sign.[1] The case reported is actually a case of 'Stroke following minor trauma' which is common in toddlers. What the authors have described in the image is actually the calcified lenticulostriate arteries. What I do not agree is the statement, 'this is the first report of a hyperdense lenticulostriate artery sign.' This sign has been nicely described previously and reported in a paper by Lingappa L et al., in 'Developmental Medicine and Child Neurology.'[2] They have described 22 toddlers in their paper and discussed the clinical presentation and the imaging features of this entity.

This entity has been described as 'Mineralising Angiopathy,' and we in India, see it very commonly. It is one of the most common causes of stroke following minor trauma in toddlers. Though the exact cause is not known, it is presumed to be due to be either genetic in origin or due to congenital infections like cytomegalovirus infection. Treatment with aspirin is usually not required and there is a high chance of recurrence if future minor trauma is not avoided [2]
