Sir, recent report on “Opsoclonus-myoclonus-ataxia syndrome associated with dengue” is very interesting [1]. In fact, opsoclonus-myoclonus-ataxia syndrome is reported in many viral syndrome including West Nile virus infection [2] and hepatitis [3]. The opsoclonus-myoclonus-ataxia syndrome is believed to be a result of neurological involvement of viral infection [4]. However, it can also be the early manifestation of some neurological neoplasm [4]. In the case of dengue, it is no doubt that the opsoclonus-myoclonus-ataxia syndrome can be a neurological complication [5]. In the present report by Tan et al. [1], an important consideration is whether there is any concomitant disorder that can result in opsoclonus-myoclonus-ataxia syndrome in dengue patient. The complete investigation to rule out occult brain neoplasm is the general rule. In the case without brain tumor, the possibility of concomitant viral infection, such as hepatitis, which can also induce opsoclonus-myoclonus ataxia syndrome should be completely sought. Conflict of interest No.
