In our case, 7-year-old female child presenting with convulsion, both eye nystagmus, right eye exotropia, left eye ptosis, both eye papilloedema, developmental delay, magnetic resonance imaging brain suggestive molar tooth appearance of cerebellar peduncles, and Bat wing appearance of the prominent fourth ventricle. Chest X-ray showing cardiomegaly and C-reactive protein positive. The aim of our study is diagnosis and management of patient with JS and increase awareness about this disease and manage it as early as possible and prevent serious complication like visual impairment.
