ABSTRACT
The uncommon, benign dysembryoplastic neuroepithelial tumor (DNET, WHO grade 1) is frequently linked to epilepsy. It is a glioneuronal neoplasm in the cerebral cortex of children or young adults defined by the presence of a pathognomonic glioneuronal element that may be linked to glial nodules and activating mutations of fibroblast growth factor receptor 1 (FGFR1) (CNS WHO grade 1 according to WHO classification of CNS and pituitary tumors, 2021 ). The cerebral cortex is primarily affected. The most frequent areas are the temporal lobe, particularly the medial lobe, frontal lobe, and other cortex. This study reports the instance of a 31-year-old male who had a history of seizures for the past 20 years and complained of a sudden headache and vomiting at the hospital. MRI revealed a cortical-based lesion in the left posterior temporo-occipital region. A biopsy sample was sent for histopathological examination. DNETs are usually benign, non-recurring lesions and rarely can be a malignant transformation. Although they are frequently stable tumors, surgical excision seldom results in recurrence.
