79-year-old female with increased CRP and purulent wound, evaluate for osteomyelitis. Several series are limited by patient motion artifact. Evaluation of the knee is limited due to metallic susceptibility artifact from the patient's total knee arthroplasty device.There is diffuse thickening and enhancement of the skin with foci of skin irregularity suggesting ulceration with overlying packing material. There is reticulation of the subcutaneous fat with associated enhancement. These findings are compatible with the stated history of cellulitis. Although the subcutaneous edema becomes confluent, particularly laterally, we see no fluid collection to suggest abscess. There is fatty atrophy of the musculature of the leg. We see no intra- or intermuscular abscess. The bone marrow signal is within normal limits, without evidence of osteomyelitis. There is subcutaneous edema and fatty atrophy of the musculature of the right lower extremity as seen on the large field-of-view series.
Limited study showing cellulitis, without evidence of osteomyelitis.
