Summary Dysembryoplastic neuroepithelial tumors (DNETs) are World Health Organization grade 1 neoplasms, typically present as isolated cortical lesions with no associated edema. We 3 rare cases of DNETs that were atypical in location (all subcortical and was bilateral), 2 which displayed substantial growth over time. All presented seizures not well controlled on medications, followed by a successful cure the epilepsy when these removed. These uniquely illustrate can be throughout brain may generate even location, possibly due to containing neurons potential for aberrant microcircuitry. The slow, nonmalignant proliferation engage epileptogenic networks, leading onset seizures. carry implications management surgically treatable lesions. Thus far, there have only been handful reported DNETs, interval monitoring.
