Abstract
A 44-year-old woman, previously treated with surgery for breast cancer and a left frontal brain metastasis, presented with seizures. 18 F-FET PET/MRI demonstrated a 18 F-FET-avid, enhancing lesion at the prior brain surgical area, suggestive of recurrence. However, subsequent surgical pathology identified only gliosis, with no tumor. This case demonstrates a limitation of 18 F-FET PET/MRI in differentiating between benign and malignant intracranial lesions.
