摘要
目的 研究鼻咽癌颅底骨破坏的CT征象。材料与方法 对病理证实的鼻咽癌患者 192 3例 (男 14 0 5例 ,女 5 18例 )进行CT扫描 ,采用常规轴位 ,层厚 4mm ,层距 4～ 5mm。用骨窗显示 :窗宽 2 2 0 0HU ,窗中心 2 5 0HU。部分病例加扫冠状位 ,窗技术不变。结果 颅底骨破坏 774例 ,占 40 .3 % ,其中男 6 0 5例 ,女 16 9例 ,年龄 13～ 80岁。蝶骨破坏最常见 ,占 76 .6 %。蝶骨各部位发病率从高至低依次为 :翼突根部 ,蝶骨体、大翼、翼突。骨破坏分为成骨型、破骨型和混合型。蝶骨根部是成骨型最好发的部位。结论 成骨型破坏是鼻咽癌颅底骨破坏的一种常见类型 ,但常被漏诊 ,应该引起重视。
Objective To study CT features of bone destruction at the base of the skull in nasopharyngeal carcinoma (NPC).Materials and Methods CT scanning was performed in 1,923 patients with pathologically proved NPC (male 1,405 and female 518) on a Siemens Somaton CR unit using bony window with slice thickness of 4 mm and interval of 4～5 mm. Additional coronal scan was done in some patients.Results Bone destruction of the skull base was found in 774 cases (male 605 and female 169), aged 13～80 years. Bone destruction was displayed in three types: osteoblastic, osteolytic or mixed type. Sphenoid bone, especially the base of pterygoid process, was most commonly involved.Conclusion Osteoblastic destruction of the skull base in NPC is very common, although its diagnosis is often missed. Correct use of window technique in an experienced radiologist will improve the demonstration of the lesions.
