Dysembryoplastic neuroepithelial tumor (DNET), a benign, mixed neuroglial tumor that most commonly occupies the temporal lobe of the cortex. The spectrum of clinical presentation varies from simple partial seizure to generalized seizure in some cases. This is a case of a 20-year-old man who presented with a drug resistant epilepsy and was found to have a DNET located in the partial lobe. Therefore, based on radiological finding the diagnosis of DNET was made. Surgical resection of the tumour was done, and the patient recovered uneventfully. The patient was discharged with antiepileptic medications, and showed a complete seizure-free for one year follow up. To the best of our knowledge, this case report brings attention to a rare location of DNET in parietal lobe, also, discusses the clinical presentation, pathological findings, different diagnostic modalities, and surgical approach to such tumour.
