“…The majority of CHSs are characterized by enhanced radionuclide uptake (compared to the anterior iliac crest) at bone scintigraphy [ 107 , 119 ]. A recent study demonstrated that elevated thallium-201 uptake was associated with almost eight times greater odds of grade 1 CHSs than enchondromas and elevated Tc-99m DMSA (V) uptake—nearly five times greater odds for CHS [ 120 ]. However, a limitation of bone scintigraphy is a subjective visual evaluation of the images and resulting inter-observer variability [ 119 ].…”

“…It has been well-established within the literature that pelvic chondrosarcoma is difficult to diagnose pre-operatively (15). Firstly, whilst there are characteristic radiological appearances, it is difficult to distinguish chondrosarcomas from benign chondroid lesions (16)(17)(18). Crim et al demonstrated only a 21 and 58% sensitivity of plain radiographs and MRI for accurately diagnosing grade 1 chondrosarcomas (19).…”
