Reason: fluid collection History: right hand erythema There is edema within the dorsal soft tissues of the wrist and hand, extending into the fingers, with a smaller amount of edema seen volarly in the palm, also extending into the fingers. More homogeneous fluid-signal intensity immediately dorsal to the extensor tendons is compatible with confluent edema, although it is impossible to exclude a developing abscess on this nonenhanced study.Aside from small foci of signal abnormality in the third metacarpal head, likely representing degenerative cysts, the bones are unremarkable, and we see no findings to suggest osteomyelitis. There is no fluid collection within the musculature of the hand.
Findings compatible with cellulitis, particularly along the dorsum of the hand, as described above. More homogeneous fluid-signal intensity immediately dorsal to the extensor tendons is compatible with confluent edema, although it is impossible to exclude a developing abscess on this nonenhanced study. If further imaging is clinically warranted, repeat study following contrast or ultrasonography may be considered.
