Paralabral Cyst: An Unusual Cause of Quadrilateral Space Syndrome*
Section snippets
CASE REPORT
A 47-year-old man had a long history of right shoulder pain. He was a former professional football player who had suffered a third degree fracture dislocation of the distal right clavicle. In 1990, he underwent an open reduction and internal fixation with excision of bone fragments, scar tissue, and debris. Fixation of an acromioclavicular separation using a Bosworth screw and reconstruction of the coracoclavicular ligament was also performed. In 1993, he began complaining of increasing
DISCUSSION
Juxta-articular cysts are a well-described entity commonly occurring adjacent to large joints such as the hip, knee, or shoulder.9, 10, 11, 12, 13, 14, 15 Parameniscal cysts of the knee are associated with meniscal tears.9 Around the hip or shoulder, the presence of a paralabral cyst is frequently associated with a labral tear.15, 16 In the shoulder, labral cysts occur most commonly in the superior or posterior regions, and only rarely occur anteriorly.15 It has been well documented that labral

2021, Journal of Chiropractic MedicineCitation Excerpt :In cases where QSS is secondary to acute peripheral artery occlusion with subsequent ischemia, emergent surgical intervention is warranted.58 Spontaneous resolution has been noted in 1 case report, where QSS was secondary to a paralabral cyst.73,84 In summary, people with a diagnosis of QSS are recommended to undergo up to a 6-month trial of care of physical therapy before surgical intervention.

2020, European Journal of RadiologyCitation Excerpt :QSS is commonly caused by trauma or dislocation of the humerus, scapula, fibrous bands and muscular hypertrophy [45]. Other causes include labral cysts, hematomas, osteochondromas, lipomas, and posterior circumflex humeral artery aneurysms [46–49]. Axillary nerve entrapment is rarely caused by abnormal origin of radial collateral artery from posterior circumflex humeral artery, accessory subscapularis muscle, and thoracic surgeries [50–52].
