Left calf pain Note that the examination is limited by susceptibility artifact from the patient's knee arthroplasty. The examination is also markedly limited by motion artifact.There is diffuse subcutaneous edema of the lower extremity which is most prominent along the medial aspect inferiorly. There is also diffuse T2 signal hyperintensity of the calf musculature particularly of the medial head of the gastrocnemius reflecting nonspecific edema. There is mild fatty atrophy of the lower extremity musculature as well. A focus of scarring is identified medially just below the level of the tibial plateau. There is no evidence of a focal fluid collection.The marrow signal of the proximal tibia and fibula is normal aside from areas of poor fat saturation. There is an irregular focus of low T1/high T2 signal intensity within the distal tibia which appears to enhance. This was not evident on a radiograph dated 1/18/2016. There is no evidence of osteomyelitis.
1. Limited exam secondary to motion artifact and the patient's knee arthroplasty.2. Diffuse subcutaneous and muscular edema of the lower extremity predominantly involving the medial soft tissues and head of the gastrocnemius.3. Focus of signal abnormality in the distal tibia may reflect a small bone infarction.
