76-year-old female with pain and swelling history of left leg abscess and lower left extremity bypass. There is diffuse fatty atrophy of the musculature about the left knee and leg. There is nonspecific subcutaneous edema, most pronounced along the medial aspect of the leg. There is increased signal abnormality within the flexor hallucis longus and gastrocnemius muscles on fluid sensitive sequences which is nonspecific. No focal fluid collection to suggest abscess formation. No bone marrow signal abnormality is identified. No findings to suggest osteomyelitis. Note is made of foci of signal void along the medial aspect of the knee which are presumably postsurgical in etiology. Linear decreased signal abnormality along the medial aspect of the knee presumably represents scarring. Although this examination was not protocoled for detailed evaluation of the knee, severe osteoarthritis affects the left knee.
Osteoarthritis of the left knee as well as nonspecific subcutaneous and soft tissue edema about the leg. No focal fluid collection to suggest abscess formation, as clinically questioned.
