Intraosseous ganglia are benign cystic and often multiloculated lesions composed of fibrous tissue with extensive mucoid changes located in the subchondral bone adjacent to a joint. This article will describe the most common types of non-inflammatory degenerative articular intraosseous cysts found in the author’s orthopedic practice, which are subchondral cysts and […] (5-9) There is only one other case in the literature describing an IOG cyst of the humerus, while most papers describe cystic lesions of the carpal and tarsal bones. They can be sequelae to chronic sprains and strains, and can be a source of juxta-articular aberrancies. [ 3 , 4 , 8 , 9 , 25 , 28 ] However, arthroscopic resection of dorsal ganglions has become increasingly popular. Treatment is surgery including curettage and bone graft. The treatment options include rotator cuff repair, excisional AC joint arthroplasty and resection of the cyst base, aspiration, hemi‐arthroplasty, and reverse total shoulder arthroplasty 1. , Histologically intraosseous ganglion cyst has to be differentiated from subchondral cyst secondary to degenerative joint disease. From their common origin at a joint or tendon, ganglion cysts may form in a wide range of locations. David Tallman, DC, NMD Articular cysts are commonly encountered in the orthopedic practice. Intraosseous ganglion cysts are rare and occur most frequently in the long bones of the lower limb and carpals. They are pockets of joint fluid that develop outside of the joint under tears of the labrum. This case demonstrated that the intraosseous ganglion of the glenoid was a benign lesion but could be a cause of suprascapular nerve entrapment syndrome. A total of 11 cases of intraosseous ganglion of the proximal humerus have been reported in the literature so far. Rotator cuff tears were present in 36 patients, and 79% of all tears occurred in supraspinatus tendon. Lennard Funk, 2011. These are also known as ganglia (or a ganglion). Intraosseous ganglion (IOG) cysts of the humerus is a rare and often painful condition. Ganglion cysts typically occur in soft tissue near limb joints. A ganglion cyst is a common, benign (noncancerous), fluid-filled lump found on joints or tendons.. Yajima H, Murata K, Kawamura K, Kawate K, Takakura Y: Treatment of intraosseous ganglia and bone cysts of the carpal bones with injectabel calcium … The most accepted surgical treatment for ganglion cysts involves removal of the masses by means of an open surgical technique. Rarely, intraosseous ganglion cysts occur, sometimes in combination with a cyst in the overlying soft tissue. Ganglion cyst. 1, 2 We report an intraosseous ganglion cyst of the sternoclavicular joint. These may … Paralabral cysts are swellings that arise around the socket of the shoulder joint (glenoid). INTRODUCTION. J Foot Ankle Surg 33:633-5,1994. Wu KK: Intraosseous ganglion cyst of the middle cuneiform bone of the foot. Paralabral Cysts. Most cysts (94%) demonstrated communication with the joint post-arthrogram. At the shoulder, they typically occur at the acromioclavicular joint or along the biceps tendon. The cause of intramuscular cysts is not entirely clear but may be similar to that of paralabral cysts in the shoulder and hip and parameniscal cysts in the knee. We present the first reported case of complete, spontaneous resolution of a massive AC joint cyst without the need for surgical intervention.
