A hematoma, in musculoskeletal (MSK) ultrasound, is a localized collection of blood outside of blood vessels, often resulting from trauma, surgery, or underlying conditions. Appearing as a fluid collection on ultrasound, its characteristics vary based on age—from anechoic (fresh) to hyperechoic/heterogeneous (clotted/organizing). MSK ultrasound is crucial for diagnosing, characterizing, and monitoring hematomas, differentiating them from other masses, and guiding interventions.
Accurate ultrasound assessment of MSK hematomas helps clinicians determine size, location, and potential complications like nerve compression or infection. Early identification through medical ultrasound facilitates timely management, improves patient outcomes, and prevents chronic issues, making precise imaging vital for musculoskeletal care.
