Lateral Ankle Sprain.
The interval elevation of the patella and increased patella-tibial tubercle distance as consistant with patellar tendon rupture.
Giant Cell Tumor of Tendon Sheath involving the extensor tendon of the 2nd digit of the hand, also referred to as localized nodular tenosynovitis. Pathologically, the tissue is identical to PVNS. Lesions contain histiocyte-like multinucleated cells and fibroblastic cells. Frequently, they contain hemosiderin deposits.
Calcium hydroxyapatite deposition disease.
Sciatic nerve stump neuroma.
Paralabral cyst extending posteriorly and impinging the sciatic nerve.
Post-traumatic seroma interposed between the medial gastrocnemius and soleus muscles following partial medial gastrocnemius tear. Ultrasound-guided seroma aspiration may allow prompt resolution of symptoms and rapid improvement in patient mobility. The use of ultrasound during these procedures allows safe and accurate needle placement and ensures complete evacuation of the fluid collection.
Immediately following aspiration of the ganglion cyst, the patient was able to painlessly perform the ballet maneuvers and great toe flexion that had previously elicited discomfort. As clinically indicated, cortisone injection into the ganglion could also be performed at the time of the initial cyst aspiration. Due to the relatively high recurrence rate of ganglion cysts, the patient will be monitored clinically for evidence of symptom recurrence.
Moderately differentiated mucin-secreting adenocarcinoma, consistent with a pulmonary origin. This matched the previous pathology of the patient's primary lung tumor.
Peripheral nerve sheath tumor of the ulnar nerve.
Congenital Muscular Torticollis.
Based on the clinical presentation, the diagnosis of meralgia paresthetica was considered most likely. Ultrasound evaluation of the lateral femoral cutaneous nerve was requested with peri-neural anesthetic injection to confirm the diagnosis.
Calcific tendinosis of the proximal hamstring tendons.
Infected Olecranon Bursitis.
Tarsal tunnel syndrome secondary to tibial nerve compression from a perineural ganglion cyst.
Treatment of choice is ultrasound-guided aspiration of the cyst with resulting nerve decompression.
Spinoglenoid notch cyst causing denervation atrophy and fatty replacement of the infraspinatus muscle.
Partial thickness ear of the proximal patellar tendon.
Nodular Pigmented Villonodular Synovitis arising from the lateral tibiotalar joint.
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.
Following the ultrasound-guided aspiration of the paralabral cyst compressing the femoral nerve, the patient experienced symptomatic relief of her femoral nerve symptoms.
Calcific tendinosis of the long head of the rectus femoris tendon at the Anterior Inferior Iliac Spine
Epidermoid inclusion cyst.
Giant cell tumor with ABC formation.
Right rectus abdominus hypertrophy with strain common in tennis players.
Traumatic peroneus brevis tear status post ultrasound guided PRP injection with healing response.
Glomus tumor of the terminal tuft.
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.
Early Osteoarthritis with Lateral Hip Impingement.
Scar encasement/neuroma formation about ulnar nerve.
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.
Linear calcification in anterior joint capsule producing anterior impingement and pain.
Large foreign body granuloma containing multiple foreign bodies.
De Quervain’s tendinitis/tenosynovitis.
Large tendon sheath effusion, inhomogeneity of the first dorsal compartment tendons with marked hyperemia on power Doppler imaging.
Isolated teres minor atrophy.
Peroneal tenosynovitis. Ultrasound shows fluid and nodular soft tissue surrounding the peroneal tendons giving rise to the soft tissue swelling seen on radiographs.
Sonographic appearances suggestive of gout. Confirmed on ultrasound guided aspiration.
