A 45-year-old woman was found to have an intraorbital mass on CT. CT images showed a markedly enhanced retrobulbar mass with optic nerve lucency, producing a characteristic "tram-track" sign. Signal intensity patterns on spin-echo MRI seemed to indicate meningioma. The pathological diagnosis was scirrhous carcinoma of the breast. This case was not distinguishable from meningioma on CT or MRI.
一名45岁女性在CT检查中发现眶内肿物。CT图像显示球后肿物明显强化，视神经透亮，呈现特征性的“轨道征”。自旋回波MRI上的信号强度模式似乎提示为脑膜瘤。病理诊断为乳腺硬癌。该病例在CT或MRI上无法与脑膜瘤区分。
