Introduction:Gliosarcoma is a rare malignant brain tumor. The clinical presentation is acute with rapid progression of symptoms. Commonly affecting the elderly, it is rare to happen in youngsters. Case description: A 28-year-old radiographer presented to us with two episodes of unprovoked seizure. He denied any medical illnesses, or trauma, fall, motor vehicle accident and fever prior to these attacks. The computed tomography (CT) of brain was normal. He was managed as epilepsy and remained symptom-free for 3 years until the unprovoked seizure recurred. Another CT of brain performed and revealed a right parietal intracranial mass. This finding was supported by magnetic reso-nance imaging scan. The histologic examination showed a biphasic pattern of glial with predominant sarcomatous component giving a diagnosis of gliosarcoma of the brain. He had completed six cycles of adjuvant chemotherapy and was asymptomatic during clinic follow up with no tumor recurrence. Conclusion: Individuals with high risk of radiation exposure particularly radiographer as in our case requires a special attention when it comes to the diagnosis of malignancy. Despite of indolent clinical presentations, a close monitoring is needed to avoid mismanagement and subsequent morbidities.
