Abstract:
Objective To investigate the pathogenesis, clinical manifestations, imaging features, and differential diagnosis of intraosseous ganglion. Methods Clinical and imaging features of 15 cases (5 men, 10 women; mean age 39.7 years) with intraosseous ganglia were retrospectively analyzed. There were 17 lesions, including 6 acetabula, 4 lunate, 3 proximal ends of tibia, 1 major tuberculum of humeral, 1 femoral head, 1 scaphoid, and 1 phalange. Results (1) Common radiological features included a unilocular or multilocular cyst surrounded by a full and thin rim of sclerotic bone in the subchondral epiphysis without any signs of degenerative joint disease. (2) Lesions were displayed as well defined round radiolucent defect or multi cystic changes with surrounding bony sclerosis or cystic and expansile change with irregular shape on CT scans. (3) CT showed an intraosseous ganglion communicating with adjacent joint in 1 patient. (4) CT values of the lesions were between 15- 80 HU. (5) Gas in the cyst could be seen in 3 cases. Conclusion Combined with patient′s age, lesion distribution, clinical manifestations, and imaging features, it is possible to make a correct diagnosis of intraosseous ganglion.
