Infection Note that the examination is significantly limited given the presence of metallic susceptibility artifact, and the lack of contrast, and extensive patient motion.The components of a total knee arthroplasty are noted. There is a extensive marrow abnormality within the distal femur, proximal tibia, proximal fibula and anterior surface of the patella. Extensive metallic susceptibility artifact overlies the soft tissues from prior surgical intervention. There is a small suprapatellar effusion. There is diffuse soft tissue edema and muscle atrophy.
1. Significantly limited examination secondary to orthopedic hardware, extensive patient motion, and a lack of complete sequences.2. Diffusely abnormal marrow signal which may relate to known leukemia or be post-treatment in nature.3. Small joint effusion and diffuse soft tissue edema.
