18F-FET PET/MRI in a Case of Gliosis Mimicking Tumor Recurrence After Surgery for Breast Cancer Brain Metastasis

Key Points

The research examines the limitations of 18F-FET PET/MRI in identifying tumor recurrence after surgery.
Patient case analysis of a woman with breast cancer and brain metastasis
Imaging assessment using 18F-FET PET/MRI
Comparison of imaging findings with surgical pathology
18F-FET PET/MRI indicated a suspected tumor recurrence
Surgical pathology revealed only gliosis, confirming no tumor presence
Highlights the challenge of accurate diagnosis using 18F-FET PET/MRI in certain contexts

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.
