Objective To evaluate the diagnostic value of CT enhanced scan in the diagnosis of orbital cavernous hemangioma. Methods 60 cases of patients with orbital cavernous hemangioma which confirmed by surgery and pathology in our hospital between January 2010 and December 2015 were selected as the study objects. CT routine plain scan and enhanced scan were performed before operation, including routine enhanced scan (routine group) and dynamic enhanced scan (enhanced group), 30 cases in each group. The respective signs were observed and compared with surgical and pathological results. The diagnostic accuracy rates of different scanning methods were compared. Results CT plain scan showed 55 cases (91.7%) located in muscle cone, 30 cases (50%) with quasi-circular shape and clear tumor boundaries; most of the density was homogeneous and moderately high. The routine group showed obvious enhancement in 13 cases and no obvious enhancement in 17 cases; The enhanced group showed obvious enhancement in 26 cases, showing characteristic of inhomogeneous progressive enhancement and no obvious enhancement in 4 cases. The confirmed diagnosis rate of orbital cavernous hemangioma in the enhanced group (86.7%) was significantly higher than that in the control group (43.3%) (P<0.001). Conclusion Compared ith CT routine enhanced scan, the accuracy of CT dynamic enhanced scan in qualitative and localization diagnosis of orbital cavernous hemangioma was obvious higher. It is suggested that CT dynamic enhanced scan could improve the accuracy rate in diagnosis of orbital cavernous hemangioma.
