RESUMO
Objective To explore the clinical manifestation,imaging features,histopathological classifications and treatment of primary orbital tumors.Methods Twenty-six cases with primary orbital tumors were retrospectively studied.Results All of 26 primary orbital tumor cases received surgical treatment.Sixteen primary orbital tumors cases were male and 10 cases were female.The mean age was 46 years (ranged from 15 to 72).The mean hospital stay was 13 d (ranged from 9 to 21).Among 26 primary orbital tumors cases,21 cases were benign tumors which included 11 cases of cavernous hemangioma,5 cases of inflammatory pseudotumor,3 cases of dermoid cyst,2 cases of venous angioma.Five cases were malignant tumors which included 4 cases of adenoid cystic carcinoma and 1 case of rhabdomyosarcoma.After operation,visual acuity improved in 9 cases,unchanged in 11 cases,decreased in 6 cases.The patients were followed up for 18-48 months (mean,25 months).There were 4 cases of malignant tumors recurrence after operation and received radical operation.While 2 patients were lost,the other 24 patients survived with tumor-free.Conclusions Surgical excision is the main and effective treatment for primary orbital tumors.To be very familiar with the imaging characteristics and local anatomy is the key for operation.Individualized treatment plan should be chosen based on clinical manifestation,imaging features and histopathological classifications.
