The image appearances of intraosseous ganglion of the wrist / 中华放射学杂志

ABSTRACT

Objective To observe the imaging features of intraosseous ganglion of the wrist. Methods The radiographs (6 cases), CT (4 cases), and MR (1 case) in 6 cases (7 lesions) of surgically confirmed intraosseous ganglion were retrospectively reviewed. Results Typical intraosseous ganglion was seen as sharp margined and cystic lesion with the size of approximately 0.5 cm in diameter. All but one lesion showed no communication with joint. No degenerative changes were seen in the joints nearby. CT was able to depict the lesions better than radiographs in 4 cases. Intraosseous ganglion was seen as slight low signal on T 1WI and slight high signal on T 2WI MR images. Conclusion Intraosseous ganglion was typically seen as sharp-margined and cystic lesion on radiographs, and it could be better demonstrated with CT and MR. With typical imaging appearance, a suggestion to the diagnosis of intraosseous ganglion could be made.
