Article Abstract

Objective: To report MRI findings of changes seen in aneurysmal bone cysts after percutaneous sclerotherapy treatment.

Materials And Methods: After applying exclusion criteria, a total of 36 patients who had aneurysmal bone cysts and undergone percutaneous sclerotherapy were included in this study. The pre-treatment and post-treatment MRIs were reviewed and multiple pre-determined MRI findings were evaluated. The presence of each post-treatment finding, as well as the time for each finding to develop, was recorded.

Results: Early post-sclerotherapy changes include increased perilesional edema and enhancement, which appear on MRI on average 5.1 months after the initial sclerotherapy. This is followed by decreased cystic areas, which can be seen on average 5.9 months after the initial treatment. The presence of fibrosis, improved cortical integrity, and improving mass effect are later post-treatment changes and appear on MRI on average 9.7 months, 10.6 months, and 16.1 months after the initial sclerotherapy, respectively.

Conclusion: The early and late post-sclerotherapy MR findings of aneurysmal bone cysts were reported in this study.
