AJR Am J Roentgenol. Response. A hip cyst is a subchondral cyst (fluid-filled space) that forms inside a joint that extends from one of the bones that forms the joint of the hip. The sac …   Subchondral cysts occur is when the damage done to the cartilage begins to harden and form fluid-filled sacs (cysts) within the joint. Enhancement of subchondral cysts was evaluated on contrast-enhanced MRI as grade 0 (absent), grade 1 (partial enhancement), or grade 2 (full enhancement). eCollection 2020 Jul. Jacobson JA, Girish G, Jiang Y et-al. Geodes are seen in a small group of disorders including: Presumably, one method of geode formation takes place when synovial fluid is forced into the subchondral bone, resulting in a cystic collection of joint fluid. Another etiology is that following a bone contusion, the contused bone forms a cyst. Background: Cvetanovich GL, Weber AE, Kuhns BD, Alter J, Harris JD, Mather RC 3rd, Nho SJ. 24) is an intraosseous cyst which occurs beneath an articular surface of a bone. NLM Bone contusion theory proponents explain that subchondral bone that has lost some of the overlying cartilage cushion is more susceptible to injury from repetitive microtrauma. They rarely cause problems by themselves but are often misdiagnosed as something more sinister and an unnecessary biopsy of a geode might be performed on the basis of the differential of an epiphyseal lesion. Subchondral bone involvement can be manifested by bone marrow edema (BME), fracture, sclerosis and/or cyst formation. Study design: 1990;49 (10): 785-7. 2020 Oct 22;9(10):e1531-e1539.

Hip arthroscopies performed on patients with subchondral cysts present on preoperative MRI should be approached with caution. The exact pathogenesis of these degenerative cysts is not certain.26,27 Subchondral cysts are most often seen in association with osteoarthritis, but may occur as the result of degeneration or injury of the overlying articular cartilage by other causes. The cyst may remain open to the joint, but more often is closed by fibrous tissue, fibrocartilage, or new bone. They can usually be first visualized on the T2 coronal series and then precisely located on the axial and sagittal views.
