Abstract:
The hallmark radiological finding in metastatic brain disease is multiple enhancing lesions. We report a case of metastatic lung cancer to the brain with a lack of contrast enhancement. We believe that this unusual finding is due to inadvertent "treatment" of the metastases with the antiangiogenic agent bevacizumab (Avastin).
