56-year-old male with right hand/arm pain and swelling for one week. Evaluate for infection. No bone marrow signal abnormality is identified. There is no evidence to suggest osteomyelitis. There is extensive diffuse increased signal abnormality in the soft tissues of the right forearm and wrist, most pronounced along the dorsal aspect of the wrist and forearm, consistent with edema/inflammation. There is a moderate amount of fluid within the radiocarpal joint. There are multiple fluid collections about the wrist. There is a 2.2 x 1.4 cm collection about the dorsal aspect of the extensor carpi ulnaris and extensor digiti minimi tendons. There is an additional fluid collection deep to the flexor digitorum tendons measuring approximately 3.1 x 1.3 cm. It should be noted that evaluation for abscess formation is limited due to lack of intravenous contrast.
Multiple focal fluid collections about the wrist, suspicious for abscess formation, with associated extensive soft tissue swelling about the wrist and forearm, as described above.
