AIM:To study the clinical and image feature of orbital hematoma, and provide evidence for diagnosis and treatment. METHODS :The patient who were treated in our department in last 4 years were collected, the etiology, clinical feature, image were analyzed. RESULTS:A total of 10 cases of hematoma, 1 case had a clear history of trauma, all patients showed exophthalmos, with different degrees of visual acuity decrease, eye movement disorders. Hematoma within the muscle cone in the cone CT showed high density, and the performance of the front showed quasi-circle. B-ultrasound within 4 days appeared as intense echoes of solid lesions, more than 4 days showed hypoechoic areas, individual had echoes interval inside, CDFI had no blood flow signals within the tumor, a routine MRI was consistent with subacute hemorrhage. Bleeding within 7 days of surgery were seen hematoma blood clot. CONCLUSION:Orbital hematoma took onset suddenly, most of which has no inducement, combined with clinical history, symptom, sign, CT, B ultrasound and MRI, we can obtain correct diagnosis. Operation is an efficient way to those who has no obvious improvement with conservative treatment , and obtains good prognosis.
