Abstract:ObjectiveTo investigate the diagnostic value of radiological examinations for cavernous hemangioma in maxillary sinus, and to evaluate the feasibility of endoscopic surgical removal of this tumor.MethodsRadiological data (CT and MRI findings) of 11 cases suffering from pathologicallyconfirmed cavernous hemangioma in maxillary sinus was analyzed retrospectively. All the patients received transnasal endoscopic surgical removal of cavernous hemangioma. The therapeutic effect was evaluated with postoperative followup, and related literature was reviewed.ResultsIn all cases, MRI showed isointense lesions in 9 cases on T1WI and hyperintense lesions in 10 on T2WI. Dynamic contrast MRI imaging demonstrated marked progressive enhancement, honeycomblike or variegated appearance in all these cases. All 11 cases received endoscopic removal of cavernous hemangioma without relapse in one year postoperatively.ConclusionsThe radiological characteristics can provide accurate information about the diagnosis of cavernous hemangioma in the maxillary sinus. In most of the patients, the tumor can be completely resected endoscopically without internal maxillary artery embolization or ligation of external carotid artery.
