Sir,

The recent report on "Dot sign and dengue encephalitis" is very interesting. [1] The finding of dot sign in diagnosis of dengue encephalitis should be commented. In this case, "transient splenial hyperintensityappearing asdot sign in magnetic resonance imaging (MRI)" is mentioned. [1] Indeed, "dot sign" is classically mentioned in some diseases, but not infectious disease as dengue. [2] Transient splenial hyperintensitycan be seen in many neurological problems such as cryptococcal meningitis [3] and epilepsy. [4] The concomitant disorder in the present case is questionable. Indeed, dengue encephalitis is an uncommon neurological presentation of dengue and the clinical features can hardly be differentiated from other encephalitis. [5] The MRI seems to be not helpful for definitive and differential diagnosis. [5]
