Gliosarcoma in a Paediatric Patient: A Rare Entity and Review of Literature

Primary Gliosarcoma is a rare malignant tumour of central nervous system in adults. It is usually a variant of Isocitrate Dehydrogenase (IDH) wild type glioblastoma. Its incidence is approximately 2% of glioblastomas and has a dismal prognosis. Most common age group is between 40-60 years of age is commonly seen in males. Paediatric gliosarcoma is even rarer than adults ones. Most common location is temporal and frontal lobes (cerebral hemisphere). Histologically it shows biphasic pattern and is composed of both glial and mesenchymal components. Both these components has monoclonal proliferations. Here, a 20-month-old boy resident of Gorakhpur presented with persistent crying for short duration in neurosurgery emergency. On magnetic resonance studies a frontotemporal lesion was found, for which he underwent tumour excision. The tumour proved to be a primary gliosarcoma. Due to malignant nature of tumour patient did not survive. Gliosacrcoma is rare adult tumour but can rarely occur in children. A differential diagnosis of gliosarcoma should be kept in mind while dealing with congenital tumours in children due its aggressive nature with poor survival outcome.
