Abstract:Collateral circulation is often secondary to a regional thrombosis. This phenomenon can lead to the detection of misleading bone lesions on imaging and is a well-known source of false-positives. Here, we present 2 different tracers PET/CT images, 18F-FDG and 18F-choline, with collateral circulation but without obvious thrombosis. Both cases displayed bone uptake, which mimicked metastasis. However, clinical follow-up ruled out metastasis and revealed false-positive bone lesions related to collateral circulatio… Show more
