Paralabral cysts are most common type of shoulder cysts found. There are three types of paralabral cysts: ganglion, synovial, and pseudocysts. When paralabral cysts are found they are associated with a torn glenoid labrum. The tear of the capsulolabral complex is caused by trauma to the shoulder. Unilocular of mutilocular cysts can occur due to the leakage of synovial fluid into the joint from associated trauma. Paralabral cysts can occur at any age. Most patients complain of pain or decreased range of shoulder motion. Plain radiographs do not detect paralabral cysts. MRI‘s are preformed and detect paralabral cysts hyper-intense area on T-2 weighted images and a hypo-intense area on T-1 weighted images. Cyst aspirations, surgery to remove cyst, and repair of gleniod labrum tears are most common treatments for paralabral cysts. Patients then follow up with physical therapy and return to their normal activies.
