目的 :探讨CT对鼻腔及副鼻窦内翻性乳头状瘤的诊断价值。材料与方法 :回顾性分析 2 3例经病理证实的鼻腔及副鼻窦内翻性乳头状瘤的CT征象 ,术后 13例行CT随访。结果 :肿瘤呈不规则软组织肿块 ,以中鼻道为中心 ,同时侵犯同侧鼻腔及副鼻窦 2 1例 ,单纯累及上颌窦 2例 ;所致骨质改变以骨质破坏多见。术后肿瘤复发率高 ( 85 % ) ,3例恶性变。结论 :CT能较好地显示鼻腔及副鼻窦内翻性乳头状瘤的病变部位、范围及术后有无肿瘤复发 ,有利于临床治疗方案的选择。
Objective: To investigate the value of CT in the diagnosis of inverted papilloma in nasal and paranasal sinuses. Materials and Methods: Twenty-three cases of pathologically confirmed CT findings of inverted papilloma of the nasal cavity and paranasal sinuses were retrospectively analyzed. Thirteen patients were followed up for CT. Results: The tumor was irregular soft tissue mass, with the middle of the nasal passages as the center, at the same time violations of the ipsilateral nasal cavity and paranasal sinuses in 21 cases, involving only the maxillary sinus in 2 cases; caused by bone destruction to more common bone destruction.
