摘　　要：眼眶海绵状血管瘤(OCH)是一种错构瘤,实质为血管窦和纤维间隔,是成年人最常见的原发于眼内的良性肿瘤。该院收治了1例OCH患者,其磁共振成像表现为右眼上直肌下方可见团块状等T_1等T_2信号,其内信号不均,大小约为25 mm×18 mm×25 mm,增强扫描呈不均匀强化,与常规的OCH磁共振显像存在差异。该例OCH不典型的表现,突显了影像学表现的多样化,对临床上类似病例的术前定性诊断,应结合病史及合理的辅助检查,提高其术前眼眶肿瘤性质的判断。Orbital cavernous hemangioma ( OCH) is a type of hamartoma, consisting of sinusoid-likevessels and fibrous capsules. OCH is the most common primary benign intraocular tumor in adults. One case ofOCH admitted to our hospital was reported in this study. Magnetic resonance imaging revealed a sub-rectusmass with iso-intensity on and T1WI and T2WI in the right eye. The mass was measured approximately 25 mmx 18 mm x25 mm in size with uneven enhanced signal, which was inconsistent with conventional MRI findingsof OCH. This OCH patient was characterized as atypical manifestations, highlighting the diverse imaging featuresof OCH. During preoperative qualitative diagnosis of similar cases, inquiry of family history and properauxiliary examinations should be performed to enhance the accuracy of preoperative assessment of the nature oforbital tumors.
