CT Evaluation in Inverted Papilloma of the Nose and Paranasal Sinuses
鼻及副鼻竇倒生性乳頭瘤之電腦斷層評估
摘要
倒生性乳頭瘤是長在鼻腔及副鼻竇一種不常見的良性腫瘤。它們有時與過敏性鼻息肉甚或鱗狀上皮癌不易區分。在証實為倒生性乳頭瘤的十八例中，有十二例作了頭頸部電腦斷層掃描，六例術後有復發迹象，其中的一例組織學檢查有惡性現象。常見的電腦斷層影像是單側性的腫塊長在中或上鼻道，僅一例下鼻道有被侵犯。另外尚可見到非特異性的骨頭變化，如骨質的破壞或侵蝕及硬化。電腦斷層檢查可評估病灶的侵犯範圍，作為手術的參考。除例行的頭部及副鼻竇攝影外，在磁振造影尚未普遍使用之前，電腦斷層檢查實為目前最佳的檢查工具。

Inverted papillomas are uncommop benign lesions in the nose and paranasal sinuses. They sometimes cannot be easily distinguished from allergic polyposis or even squamous cell carcinoma, Twelve of 18 proved cases of inverted papilloma were studied by CT. Recurrence was noted in six of our cases. One of them was histologically malignant. A common CT presentation was a unilateral mass in the nasal fossa involving the middle and/or superior meatus. The inferior meatus was involved only in one case. Nonspecific bony changes such as destruction or erosion, and sclerosis were noted in CT. CT is of great help in evaluating the extent of the lesion for surgical planning. It is the examination of choice after plain radiographs of the skull and paranasal sinuses.
