ABSTRACT
Regardless of an appropriate radiation therapy administered to a patient with a brain tumor, clinical and radiological evidence of progression may still develop because of a recurrence of the tumor and/or radiation necrosis, or even rarely, a radiation induced neoplasm. The evaluation of tumor recurrence and radiation-induced necrosis presents a diagnostic challenge. A thirty eight year old woman was treated for a focal motor seizure on the right side of her face.with a fractionated external beam radiotherapy under the impression of cystic astrocytoma in the left frontoparietal region. After 6 months, she developed a headache, nausea and vomiting, dysphagia, and secondary generalized seizure. A follow-up brain MRI showed a high signal mass lesion in a T2 weighted image and a fluorodeoxyglucose PET revealed hypometabolism in the left frontoparietal lobe, suggesting radionecrosis. It was confirmed as radionecrosis with an expanding edema by open biopsy. We report a cerebral radiation necrosis mimicking recurrent brain tumor.
