【摘要】：目的探討鼻腔腫塊影像學(xué)特征及生長方式特點與病變的良惡性的相關(guān)性，，旨在提高影像學(xué)診斷的準(zhǔn)確性。 方法搜集2006年1月—2013年1月我院323例鼻腔腫塊的CT和/或MRI檢查影像資料，所有病歷均經(jīng)手術(shù)病理證實。對腫塊發(fā)生單/雙側(cè)別、形態(tài)與邊緣、骨質(zhì)改變、生長范圍、相鄰結(jié)構(gòu)受累情況、上頜旁脂肪層改變、生長方式、腫瘤中心、基底、生長方向、腫瘤密度與信號、強(qiáng)化特點、鈣化、壞死/囊變及出血與病灶良惡性的相關(guān)性進(jìn)行分析統(tǒng)計。 結(jié)果323例鼻腔腫物患者中，良性腫塊占233例（72.14%），惡性腫瘤占90例（27.86%）。單因素分析表明腫塊的形態(tài)、邊緣、骨質(zhì)改變、生長范圍、相鄰結(jié)構(gòu)受累情況、上頜旁脂肪層改變、生長方式、基底面、生長方向、MRI強(qiáng)化方式及壞死/囊變與病灶的良惡性有相關(guān)性（P0.05）。其中骨質(zhì)破壞和浸潤性生長是惡性腫瘤最重要的征象，大多數(shù)惡性腫瘤形態(tài)不規(guī)則，邊界不清，基底面不清；腫塊超腔生長、上頜竇后方脂肪墊受累和囊變/壞死多見于惡性腫瘤。腫塊的發(fā)生單/雙側(cè)別、腫瘤中心、CT及MRI平掃表現(xiàn)、CT強(qiáng)化方式、CT及MRI強(qiáng)化程度、鈣化及出血與病灶的良惡性無明顯相關(guān)性（P0.05）。 結(jié)論鼻腔腫塊的形態(tài)、邊緣、骨質(zhì)破壞、生長范圍、相鄰結(jié)構(gòu)受累情況、上頜旁脂肪層改變、生長方式、基底、生長方向、MRI強(qiáng)化方式及壞死/囊變可作為判別腫物良惡性的參考指標(biāo)。
[Abstract]:Objective to investigate the correlation between the imaging features and growth pattern of nasal masses and the benign and malignant lesions in order to improve the accuracy of imaging diagnosis. Methods CT and / or MRI images of 323 cases of nasal masses from January 2006 to January 2013 were collected. All cases were confirmed by operation and pathology. The tumor was characterized by unilateral / bilateral differentiation, morphology and margin, bone change, growth range, involvement of adjacent structures, changes of perimaxillary adipose layer, growth pattern, tumor center, basement, growth direction, tumor density and signal intensity, enhancement characteristics. The correlation of calcification, necrosis / cysts and hemorrhage with benign and malignant lesions was analyzed. Results among 323 cases of nasal masses, 233 cases were benign masses (72.14%), 90 cases were malignant tumors (27.86%). Univariate analysis showed that the shape, margin, bone change, growth range, adjacent structure involvement, perimaxillary fat layer change, growth pattern, basal surface, The pattern of MRI enhancement and necrosis / cysts were correlated with benign and malignant lesions (P0.05). Among them, bone destruction and infiltrative growth are the most important signs of malignant tumor. Most malignant tumors are irregular in shape, unclear in boundary and unclear in basal surface. Posterior maxillary sinus fat pad involvement and cystic / necrotic are more common in malignant tumors. There was no significant correlation between benign and malignant lesions (P 0.05). There was no significant correlation between the enhancement of CT and MRI, calcification and hemorrhage (P0.05). Conclusion the shape, edge, bone destruction, growth range, involvement of adjacent structures, changes of the perimaxillary adipose layer, growth pattern, and basement of the nasal mass were observed. The pattern of MRI enhancement and necrosis / cystic degeneration can be used as a reference index for differentiating benign and malignant tumors.
