摘　　要：本文报告４２例鼻与鼻旁窦恶性肿瘤的ＣＴ诊断，癌２７例，肉瘤１０例，其他恶性肿瘤５例。恶性肿瘤的早期诊断是窦腔内软组织肿块及窦壁骨质破坏。显示这两种征象，ＣＴ明显优于平片，特别是ＣＴ能很好地显示恶性肿瘤的侵犯范围，并能区别侵蚀性骨质破坏与骨改建，有利于良、恶性肿瘤的鉴别。肿瘤进一步发展突破窦壁产生窦外软组织结构的改变，是恶性肿瘤特征表现，对恶性肿瘤诊断具有重要意义。CT diagnosis of 42 malignant tumors of the nasal and paranasal sinuses was studied,27 with carcinoma,10 w1th sarcoma and 5 with other tumors.The early diagnosis of malignant tumors are based on the soft mases in the sinus and the destruction of adjacent bone wall.CT scan is apparently superior to plain film in showing these two signs.Especially,CT scan can very nicely reveal the extent invaded by malignant tumors with the difference between aggressive bone destruction and bone remodeling.These help distinguishing between benign tumors and malignant tumors.When tumors develop further and invade the soft tissue outside of sinus,malignant tumors will show their particular characteristics which are significant to their diagnosis.
