Gelfoam embolization or 125I seed implantation may be a more effective treatment than surgical treatment for giant benign sacral neurogenic tumors.
BACKGROUND
The goal of the present study was to assess the effects of computed tomography (CT)-guided iodine-125 (125I) seed implantation or gelatin sponge particle (GSP) embolization on patients with giant benign sacral neurogenic tumors.


METHODS
A total of 24 cases with giant sacral neurogenic tumor were performed in a retrospective study between 2000 and 2012. Nineteen cases received surgical resection, and five cases received non-surgical treatment. In surgical group, patients with type III sacral tumor had received a combined anterior-posterior approach and patients with type IV were treated with simple anterior approach. In non-surgical group, CT-guided 125I seed implantation or GSP embolization was applied to occlude vessels. Besides, CT scanning or magnetic resonance imaging was used to assess the size and development of tumors.


RESULTS
Two of the five patients were treated three times with GSP embolization, one had received GSP embolization combined with CT-guided 125I seed implantation, one case did not receive any treatment, and one patient was lost to follow-up. Patients in non-surgical group were followed up for 2-8 years.


CONCLUSIONS
Our study suggested that CT-guided 125I seed implantation or GSP embolization treatment is very useful to slow down the development of giant benign sacral neurogenic tumors.
