We present the case of a 13-month-old girl with a right occipital cortical alteration on MRI that proved to be a growing lesion. Tumor growth had been observed over a period of 15 months before total resection was performed, revealing a dysembryoplastic neuroepithelial tumor WHO grade I. This case shows that dysembryoplastic neuroepithelial tumors can present as growing neoplasias. It underlines the importance of obtaining histologic diagnosis and close follow-up examinations using MRI, even in so-called stable lesions that are only unveiling through epileptic seizures.
