The cavernous hemangioma is the most common benign orbital tumor in adults. Its presentation is during the forth to fifth decades with a slowly progressive unilateral proptosis. Intraconal cavernous hemangiomas may be difficult to differentiate from other intraconal lesions such as schwannomas, meningiomas and hemangiopericytomas. We report a case of orbital cavernous hemangioma diagnosed by Tc-99m RBC scintigraphy. Tc-99m RBC scintigraphy revealed a typical scintigraphic pattern in which there is intense focally increased uptake on the delayed image. We conclude that Tc-99m RBC scintigraphy can be a useful method in the differential diagnosis of orbital cavernous hemangioma as in hepatic hemangioma.
海绵状血管瘤是成人最常见的眼眶良性肿瘤。其发病于40至50岁，表现为缓慢进展的单侧眼球突出。眶内海绵状血管瘤可能难以与其他眶内病变如神经鞘瘤、脑膜瘤和血管外皮细胞瘤相鉴别。我们报告一例通过锝-99m红细胞闪烁扫描术诊断的眼眶海绵状血管瘤病例。锝-99m红细胞闪烁扫描术显示出典型的闪烁图像，即在延迟图像上有强烈的局灶性摄取增加。我们得出结论，锝-99m红细胞闪烁扫描术在眼眶海绵状血管瘤的鉴别诊断中可以像在肝血管瘤中一样成为一种有用的方法。
