Fig. 2D —36-year-old man with recurrent chondrosarcoma. Axial MR images reveal large mass emanating from femur and showing T1 signal isointense to muscle (TR/TE, 500/9) (C), high signal intensity on fat-saturated T2-weighted image (4,000/83) (D), and heterogeneous enhancement after administration of IV contrast material (gadopentetate dimeglumine, 0.1 mmol/kg of body weight) on fat-saturated T1-weighted image (600/9) (E). Despite areas of nonenhancement (necrosis), a larger degree of enhancing soft tissue is present than would be expected with abscess. Relative lack of soft-tissue inflammation would also be unusual for newly developed abscess in absence of antibiotic therapy.
