Soft Tissue Trauma

Achilles Rupture Disruption of the tendon - edema Normal

Achilles Rupture T2 image Focal high signal in tendon (white) Irregular appearance to tendon Tendon normally low signal (black)

Felt pop (“weekend warrior” athlete)

Knee injury Normal comparison

ACL Tear Normal comparison ACL

ACL Tear #2 Normal comparison ACL

Knee Trauma

Bone Contusions Patellar dislocation/relocation pattern Bone edema as result of contusion See high signal from bleeding/ fluid in bone marrow Kissing lesions during dislocation of patella

Knee pain Normal

Anterior horn lateral meniscus tear Anterior horn meniscal tear High signal with extension to the superior surface Normal

Knee Pain

Radial tear lateral meniscus Normal High signal medial posterior lateral meniscus = tear

Knee pain basketball player Normal

Jumper’s knee (patellar tendinosis/partial tearing) High signal from edema in the tendon and adjacent tissues Normal

Muscle Tear Coronal section of the thigh High signal on Fat suppressed images Fluid-Hematoma in adductor muscle group Compare to right thigh

Myositis Ossificans Amorphous bone formation in soft tissues Likely related to prior trauma

Widened Mediastinum Deceleration injury Widened superior mediastinum Must exclude positional factors (supine patient, AP film) CT can identify blood Angiogram to separate aortic injury from other vessel injuries

Aortic Tear Arch aortogram Arrow indicates area of aortic tear
