Abstract
Our study aimedto investigate the factors associated with residual cavernous sinus extra-axial cavernous hemangiomas (ECHs) progression after surgery. This retrospective study consecutively included patients of cavernous sinus ECHs with incomplete lesion resection from February 2012 to January 2024. The progression of the lesions was defined as new lesions or a growth of residual lesion (≥ 10% increase in volume). Cox regression analysis was used to determine factors associated with residual lesion progression. Kaplan-Meier analysis was conducted to estimate the cumulative incidence of residual lesion progression. Sixty patients were included in this study. During the follow-up, there were 31 (51.7%) residual lesions underwent progression, whereas 29 (48.3%) patients were nonprogressive. Multivariate Cox analysis showed that the homogeneous enhancement lesion was correlated with the residual lesion progression (HR, 8.17 [95% CI, 1.03-64.58]; p = 0.046). Kaplan-Meier survival analysis indicated that the rate of homogeneous enhancement lesion progression (3.7 per 10 person-years) was significantly higher than that of the heterogeneous enhancement group (0.5 per 10 person-years; p = 0.019). Fourteen of the 31 patients with lesion progression underwent radiotherapy, and all of them experienced control over the progression of their lesions. This study found thatend-of-treatment residual lesions are not rare in patients with cavernous sinus ECHs and the MRI feature is helpful to predict the progression of residual lesions.
