眼眶血肿的临床和影像学分析

Analysis of the clinical and image feature of orbital hematoma

摘要:

目的:研究眼眶血肿的临床和影像学表现,为临床诊断和治疗提供依据。方法:收集我科近4a(2006-08/2010-10)住院患者,对其病因、临床特点及影像学表现进行分析。结果:眼眶血肿患者10例,其中1例有明确外伤史,所有患者均表现为眼球突出,不同程度的视力下降,眼球运动障碍。血肿位于肌锥内CT表现为锥形高密度影,前部则表现为类圆形。B超4d内显示为密集回声的实性病变,>4d则表现为低回声区,个别内部有回声间隔,CDFI肿瘤内部无血流信号,1例行MRI符合亚急性出血表现。出血7d内手术的患者血肿内可见血凝块。结论:眼眶血肿起病突然,多无明确诱因,结合病史、症状、体征和CT和B超及MRI检查基本可以确诊,对于保守治疗症状无好转的患者,可以手术治疗,预后良好。

Abstract:

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.
