Rotator cuff muscle tear is a common finding among adults and acromioclavicular cyst is a rare secondary manifestation. This case report describes the clinical presentation and workup diagnosis of a patient with acromioclavicular cyst in context of massive rotator cuff tear. Woman, 83-year-old developed a tumefaction over the left acromioclavicular joint. She had pain, limitation on active range of motion and function limitation of the left shoulder. The X-ray revealed superior humeral head displacement and signs of arthropathy. The MRI revealed "geyser sign" and identified an acromioclavicular cyst secondary to cuff tear arthropathy. Aspiration was not performed due to high recurrence rate and surgical removal was decided. Clinicians should be aware of this rare complication of rotator cuff tear, demanding exclusion of other possible causes of acromioclavicular cyst and offer suitable treatment options.
肩袖肌肉撕裂在成年人中很常见，而肩锁关节囊肿是一种罕见的继发表现。本病例报告描述了一名肩袖巨大撕裂患者的肩锁关节囊肿的临床表现和检查诊断。一名 83 岁女性出现左侧肩锁关节上方肿胀。她有疼痛、主动活动范围受限和左肩功能受限。X 光显示肱骨头向上移位和关节炎迹象。MRI 显示“喷泉征”，并确定肩锁关节囊肿继发于肩袖撕裂性关节炎。由于高复发率，未进行抽吸，决定手术切除。临床医生应意识到肩袖撕裂的这种罕见并发症，需要排除肩锁关节囊肿的其他可能原因，并提供合适的治疗选择。
