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.
  • US Pathology Studies Submission Guidelines – a quick reference guide to a successful submission.

Quadriceps Hematoma and Myositis Ossificans
22-year-old male Division I basketball player presents to clinic for re-aspiration of large quadricep hematoma that was sustained during a basketball game about four weeks prior. Initial aspiration was completed two weeks prior. Athletic trainer stated right thigh swelling had recurred, and the patient was having limited knee flexion.
 
Acute Distal Triceps Tendon Rupture
78-year-old male presenting to clinic after a fall at home with posterior elbow pain, bruising, and palpable defect just proximal to the olecranon.
 
Radial Tunnel Syndrome
A 52-year-old female presented with insidious onset of left lateral elbow pain that radiated over the dorsal aspect of the forearm, which had been bothering her for a few months. Motor and sensory exams of the left upper extremity were normal. There was no pain with passive wrist flexion and resisted wrist extension. She had tenderness to palpation over the radial tunnel, but no tenderness over the lateral epicondyle. Tinel sign was positive at the radial tunnel.
 
Prepatellar Bursitis of the Knee
71 yo male presents with right anterior knee pain and swelling after a fall onto the right knee 2 months ago. Right knee pain is aggravated by kneeling. Exam shows a circular subcutaneous fluctuant fluid collection over the patella measuring 6 cm in diameter without redness, warmth to touch or drainage. There is mild tenderness to palpation of the fluid collection but no tenderness to palpation of the medial or lateral joint lines. Range of motion and strength of the right knee are normal.
 
Midportion Achilles Tendinopathy and Partial Tear
A 55-year-old male presented with a one-year history of insidious onset right posterior ankle pain. He is an avid runner, hiker, and rock climber but has been unable to engage in these activities in recent months due to worsening symptoms. On physical examination, the midportion of the right Achilles tendon is markedly thickened and tender to palpation. The patient is unable to perform a single-leg calf raise because of pain.
 
Insertional Achilles Tendinopathy and Haglund Syndrome
A 54-year-old female runner presented with a two-year history of insidious onset posterior ankle pain that began while running. Over the past two months, the pain has intensified significantly, ultimately preventing her from continuing to run. On physical examination, there is tenderness over the superior aspect of the posterior calcaneus at the Achilles tendon insertion. She is able to perform single-leg calf raises and single-leg hops, both of which reproduce her symptoms.
 
Anterior Cruciate Ligament Cyst
A 26-year-old female weightlifter with previous right tibial plateau fracture, sustained two years ago from dropping a barbell during a snatch attempt, presented with right knee pain and limited knee flexion. Pain was deep and worsened with squatting and lunging, limiting her return to sport.
 
Peripheral Nerve Sheath Tumor
77-year-old cyclist presented with acute right lower leg and ankle pain with an associated soft tissue mass just proximal to the lateral malleolus. The symptoms began gradually, without trauma, a few weeks prior to presentation. Exam of the right ankle was notable for pain with direct palpation over the area with radiating pain and numbness into the lateral ankle and foot. There was no weakness or skin changes. A right ankle x-ray demonstrated no osseous abnormalities.
 
Lateral Elbow Tendinopathy
48 yo M presents with 1 year history of lateral elbow pain that has persisted despite completing at least 6 months of physical therapy and home exercise program to include isometrics, eccentrics, modified activity and relative rest. Exam shows tenderness to palpation over the lateral common extensor tendon and pain with resisted wrist extension and middle finger extension.
