The pineal gland is a small pinecone-shaped and functionally endocrine structure located in the epithalamus region. Developmentally, the pineal gland is considered as a part of the epithalamus. It plays a role in the entrainment of the circadian rhythms of an organism by producing melatonin, a functionally important hormone. Lesions of the pineal region are rare compared to other parts of the brain. A lesion may be tumorous or non-tumorous in nature. The most common lesions are tumors that are pineal parenchymal tumors (PPT) in origin. Gliomas are the second most common tumors in the pineal region. We report a case of a high-grade oligodendroglioma, not commonly seen in the pineal region, in a 45-year-old male. The patient was suspected to have a mass in the pineal region on a computed tomography (CT) scan and histology confirmed the diagnosis of oligodendroglioma. This is a unique case because only five such cases have been reported so far.
