Abstract: This image highlights a diagnostic pitfall in a 65-year-old patient with recurrent glioblastoma. 18F-FET-PET revealed 2 hotspots with focally enhanced uptake: local tumor recurrence (TBRmax 2.3) on the left and another lesion in the right anterior cingulate gyrus (TBRmax 1.8), suspicious for a distant tumor manifestation. However, multimodal MRI revealed a benign capillary telangiectasia in the anterior cingulate gyrus. While 18F-FET-PET is highly sensitive for detecting tumor activity, vascular malformations may also exhibit moderate tracer uptake. Therefore, careful interpretation and comparison with multiple MRI sequences are essential.
