Evaluation of over 255 patients with sellar and parasellar lesions allowed study of the computed tomographic (CT) appearance of the cavernous sinus. Optimal visualization of the cavernous sinus was obtained with continuous contrast enhancement of both axial and coronal tomograms. The coronal projection provided imaging of cranial nerves with the cavernous sinus. The intracavernous carotid artery was seen only if it were calcified or encased by tumor extending into or invading the sinus. CT criteria suggesting an abnormal cavernous sinus are: (1) asymmetry of size, (2) asymmetry of shape, particularly the lateral wall, and (3) focal areas of abnormal density within the sinus. The neurovascular anatomy of the cavernous sinus is reviewed and correlated with CT findings. Discrepancies between anatomic and CT appearance are discussed.
对255例以上蝶鞍区和鞍旁病变患者的评估，使得对海绵窦的计算机断层扫描（CT）表现的研究成为可能。通过轴向和冠状断层图像的连续对比增强，可获得海绵窦的最佳可视化效果。冠状位投影可对海绵窦内的颅神经进行成像。仅当海绵窦内的颈内动脉钙化或被延伸至或侵入海绵窦的肿瘤包绕时，才能看到该动脉。提示海绵窦异常的CT标准为：（1）大小不对称；（2）形状不对称，尤其是外侧壁；（3）窦腔内密度异常的局灶性区域。本文回顾了海绵窦的神经血管解剖结构，并将其与CT表现进行了关联。还讨论了解剖结构与CT表现之间的差异。
