We report a case of dysembryoplastic neuroepithelial tumor (DNT) in a 12-year-old girl who had experienced generalized convulsions. A multinodular cystic mass was located at the postcentral gyrus. During a 5-year period of MRI observation, the tumor had enlarged slowly. Histological examination of the specimen revealed that the tumor was composed of microcystic components with alveolar pattern and consisted of oligodendrocyte-like-cells, astrocytes, and neurons ; however, there was no evidence of malignant transformation. These facts suggest that the DNTs in the rolandic area should be considered as a possible diagnosis when the tumor shows slow but definite growth.
