AMSSM LIBRARY OF SPORTS ULTRASOUND PATHOLOGY


Objective
The Sports Ultrasound Committee looks to create an educational resource directed at residents, fellows, and other learners to review both common and unusual pathology within sports ultrasound using case examples. In exploring the library of sports ultrasound pathology, we intend for learners to gain an appreciation for the nuances of ultrasound imaging and increased confidence in recognition of abnormal findings.

Submission Guidelines

  • Current sports medicine fellows are particularly encouraged to submit, with faculty guidance.
  • If a trainee is preparing the submission, the content should be reviewed with a local attending to verify ultrasound image quality and image interpretation accuracy.
    • Following submission, a secondary review will be performed by an AMSSM subcommittee. Edits may be suggested or if images are of low quality, the case may be rejected. Thereafter, the accepted content will be posted and available for member review.
  • All content must be de-identified prior to submission.
  • High quality images and/or videos should be submitted. Low quality images will not be accepted.

Posterior Neck Lipoma
A 22-year-old male college baseball player presented for a posterior neck "bump" that was non-painful and slowly increasing in size over the course of one year. Exam revealed a mobile/non-fixed mass, measuring approximately 3.5 x 3.5 cm in size, cephalad to the T1 prominence without any pain to palpation or overlying erythema noted.
 
Left Knee Hemarthrosis
A 73-year-old female presented to the Sports Medicine clinic with concerns of left knee effusion, tenderness throughout the joint, and positive McMurray testing following a low-intensity "plant-and-twist" injury 5 days prior. There was a moderate effusion present in the left knee without warmth or erythema appreciated.
 
Dorsal Wrist Ganglion Cyst
A 12-year-old male football athlete presented for an insidious onset of progressive dorsal wrist swelling and pain with wrist extension over the previous 1 year.
 
Ulnar Neuropathy at Guyon’s Canal due to a Mass
A 51-year-old right-hand-dominant female presented with a 3-week history of insidious-onset throbbing, aching pain radiating from the right elbow to the hand, with associated hand weakness and a catching sensation in the wrist. She reported distal tingling when the catching occurred. Physical examination was notable for a positive Wartenberg sign, with the fourth and fifth digits abducted at rest, and 1/5 strength with finger adduction and abduction. Sensation was diminished in the ulnar distribution distal to the wrist. She was otherwise neurovascularly intact.
 
1st CMC Osteoarthritis
A 58-year-old male presented with a 1-year history of worsening pain over his left 1st CMC joint, which was worse with thumb movement in multiple planes. He denied any specific mechanism of injury but endorsed a lifelong hobby of training and riding horses.
 
Achilles Paratenonitis
A 23-year-old male football student-athlete presented with acute onset of mild pain and increased swelling around the mid-portion of his Achilles tendon without a specific precipitating mechanism of injury. He had no history of previous Achilles tendon issues.
 
Heterotopic Ossification After Radius Fracture Repair
A 51-year-old male underwent an open reduction and internal fixation with a surgical plate of a left distal radius fracture from a fall. Recovery was complicated by delayed wound healing and continued pain over the fracture site with persistent paresthesias in the dorsal thumb and index finger, for which he presented to clinic at 5 months post-op. A CT of the wrist demonstrated nonunion of the distal radius. Exam was notable for limited ROM in active flexion of the left thumb IP and index finger DIP and PIP joints. He also had limited wrist extension due to his dorsal bridge plate.
 
Ruptured Baker's Cyst
A 64-year-old male presented with 3 months of left knee pain and swelling after sustaining a work injury. The patient reported swelling in the back of the knee with a fullness sensation down his calf into the ankle. Exam was notable for swelling in the posterior knee, lateral joint line tenderness to palpation, and pain with knee hyperflexion.
 
Rectus Femoris Muscle Injury
A 21-year-old female Division I collegiate soccer player presented with a one-week history of insidious-onset sharp pain in the left anterior thigh, localized to the distal aspect of the proximal third of the thigh. Symptoms were exacerbated by sprinting and refractory to conservative therapies, including dry needling, Graston technique, and electrical stimulation. Pain was alleviated with rest and ball work (passing and shooting).
 
Popliteus Partial Tear and Tendinopathy
A 43-year-old male professional skydiver presented with left lateral knee pain after a hard landing. Pain was described as a burning sensation that started laterally and radiated towards his patella.
