Ultrasound of the Month Diagnosis Index

 Case 22 Diagnosis:

Nodular Pigmented Villonodular Synovitis arising from the lateral tibiotalar joint.

Case 21 Diagnosis:

Myxomatous tumors of the soft tissues are a heterogeneous group of lesions, both benign and malignant, that show an overproduction of mucopolysaccharide substances. Characterized by a mixture of primitive mesenchymal cells and myxomatous stroma.  

Case 20 Diagnosis:

Following the ultrasound-guided aspiration of the paralabral cyst compressing the femoral nerve, the patient experienced symptomatic relief of her femoral nerve symptoms.

Case 19 Diagnosis:

Calcific tendinosis of the long head of the rectus femoris tendon at the Anterior Inferior Iliac Spine

Case 18 Diagnosis:

Schwannoma

Case 17 Diagnosis:

Epidermoid inclusion cyst

Case 16 Diagnosis:

Giant cell tumor with ABC formation.

Case 15 Diagnosis:

Sindig-Larson-Johansson syndrome.

Case 14 Diagnosis:

Right rectus abdominus hypertrophy with strain common in tennis players.

Case 13 Diagnosis:

Traumatic peroneus brevis tear status post ultrasound guided PRP injection with healing response.

Case 12 Diagnosis:

Glomus tumor of the terminal tuft.

Case 11 Diagnosis:

Lateral epicondylitis with deep surface tear of extensor tendon origin/lateral collateral ligament with seroma formation.Ultrasound guided seroma aspiration and platlet rich plasma injection.

Case 10 Diagnosis:

Early Osteoarthritis with Lateral Hip Impingement.

Case 9 Diagnosis:

Scar encasement/neuroma formation about ulnar nerve.

Case 8 Diagnosis:Lateral femoral cutaneous nerve entrapment

Initial imaging shows hypoechoic scarring surrounding the nerve near the Iliac crest and Sartorius origin. Ultrasound guided perineural injection was Performed resulting in symptomatic relief.

Case 7 Diagnosis:

Linear calcification in anterior joint capsule producing anterior impingement and pain.

Case 6 Diagnosis:

Large foreign body granuloma containing multiple foreign bodies.

Case 5 Diagnosis:

De Quervain’s tendinitis/tenosynovitis.

Large tendon sheath effusion, inhomogeneity of the first dorsal compartment tendons with marked hyperemia on power Doppler imaging.

Case 4 Diagnosis:

Isolated teres minor atrophy

• Atrophic muscle appears echogenic and and diminutive in size
• Normal muscle is hypoechoic on ultrasound
• Teres minor atrophy often due to injury of the axillary nerve as it passes through the quadrilateral space

Case 3 Diagnosis:

Peroneal tenosynovitis. Ultrasound shows fluid and nodular soft tissue surrounding the peroneal tendons giving rise to the soft tissue swelling seen on radiographs.

Case 2 Diagnosis:

Osteomylitis.

Case 1 Diagnosis:

Sonographic appearances suggestive of gout. Confirmed on ultrasound guided aspiration.
