Our aim was to review the imaging findings of relatively common lesions involving the cavernous sinus (CS), such as neoplastic, inflammatory, and vascular ones. The most common are neurogenic tumors and cavernoma. Tumors of the nasopharynx, skull base, and sphenoid sinus may extend to the CS as can perineural and hematogenous metastases. Inflammatory, infective, and granulomatous lesions show linear or nodular enhancement of the meninges of the CS but often have nonspecific MR imaging features. In many of these cases, involvement elsewhere suggests the diagnosis. MR imaging is sensitive for detecting vascular lesions such as carotid cavernous fistulas, aneurysms, and thromboses.
我们的目的是回顾累及海绵窦（CS）的相对常见病变的影像学表现，如肿瘤性、炎症性和血管性病变。最常见的是神经源性肿瘤和海绵状血管瘤。鼻咽癌、颅底和蝶窦的肿瘤可延伸至海绵窦，神经周围和血行转移瘤也可如此。炎症性、感染性和肉芽肿性病变表现为海绵窦脑膜的线性或结节状强化，但通常具有非特异性的磁共振成像（MR）特征。在许多此类病例中，其他部位的受累情况有助于诊断。MR成像对检测血管病变，如颈内动脉海绵窦瘘、动脉瘤和血栓形成很敏感。
