A patient presented with an isolated left sixth nerve palsy. Magnetic resonance imaging revealed a sharply marginated 3 cm lesion in the left cavernous sinus, which was isointense to gray matter on T1-weighted images, hyperintense on T2-weighted images, and enhanced with paramagnetic contrast material. Cerebral angiography showed a homogeneous blush fed by an enlarged meningohypophyseal artery. The neuroimaging findings were thought to be most consistent with the diagnosis of a cavernous sinus meningioma. At the time of surgery, a vascular mass was encountered, and a biopsy was consistent with a cavernous hemangioma. This report describes the clinical and neuroimaging features of cavernous sinus hemangiomas that may help to differentiate them from other cavernous sinus lesions.
一名患者出现孤立性左侧展神经麻痹。磁共振成像显示左侧海绵窦内有一个边界清晰的3厘米病变，在T1加权图像上与灰质等信号，在T2加权图像上呈高信号，并在使用顺磁性对比剂后强化。脑血管造影显示由增粗的脑膜垂体动脉供血的均匀染色。神经影像学表现被认为最符合海绵窦脑膜瘤的诊断。手术时，发现一个血管性肿块，活检结果符合海绵状血管瘤。本报告描述了海绵窦血管瘤的临床和神经影像学特征，可能有助于将其与其他海绵窦病变区分开来。
