ganglionic cyst of bone

ganglion cyst of bone; Intraosseous ganglion
The intraosseous ganglion is a cystic lesion of bone most frequently located in the subchondral epiphysis of long bones without direct communication with a joint cavity.
Common radiologic features usually include a unilocular cyst surrounded by a thin rim of sclerotic bone in the subchondral epiphysis in the absence of other features of degenerative joint disease.
Histologically, the ganglia are usually composed of a cystic space without epithelial lining, often filled with gelatinous, mucoid material and occasional foamy macrophages.
