【摘要】：目的:探討周?chē)托》伟?SPLC)的MSCT征象及與局灶性機(jī)化性肺炎(FOP)的鑒別。方法:回顧性分析經(jīng)病理證實(shí)、以孤立性肺結(jié)節(jié)為表現(xiàn)的58例SPLC和58例FOP的臨床和MSCT資料,比較兩者的MSCT征象及強(qiáng)化程度差異,并分析以強(qiáng)化程度為指標(biāo)診斷SPLC的效能。結(jié)果:58例SPLC中圓形或類(lèi)圓形42例,不規(guī)則形16例;邊界清楚46例,邊界模糊12例;深分葉33例,淺分葉7例;長(zhǎng)毛刺8例,短毛刺37例;棘狀突起19例,暈征8例,空泡6例,支氣管充氣征17例,壞死7例,胸膜凹陷征34例,胸膜增厚6例,血管集束征20例。58例FOP中圓形或類(lèi)圓形20例,不規(guī)則形38例;邊界清楚19例,邊界模糊39例;深分葉11例,淺分葉8例;長(zhǎng)毛刺32例,短毛刺9例;棘狀突起11例,暈征21例,空泡11例,支氣管充氣征13例,壞死10例,胸膜凹陷11例,胸膜增厚42例,血管集束征18例。經(jīng)卡方檢驗(yàn)發(fā)現(xiàn)兩組形態(tài)、邊界、深分葉、長(zhǎng)毛刺、短毛刺、暈征、胸膜凹陷征、胸膜增厚差異有統(tǒng)計(jì)學(xué)意義。58例SPLC中36例呈結(jié)節(jié)狀均勻性強(qiáng)化,17例呈不均勻斑片狀強(qiáng)化,5例輕度或無(wú)強(qiáng)化。FOP以不均勻或環(huán)形強(qiáng)化為主。兩組強(qiáng)化程度差異具有統(tǒng)計(jì)學(xué)意義。以Ⅱ級(jí)、Ⅱ~Ⅲ級(jí)強(qiáng)化為診斷指標(biāo)診斷SPLC的陽(yáng)性似然比分別為4.67、1.67,診斷效能差。結(jié)論:綜合分析SPLC與FOP的MSCT平掃及增強(qiáng)表現(xiàn)有助于鑒別診斷并減少誤診。
[Abstract]:Objective: to investigate the MSCT features of small peripheral lung cancer (SPLC) and its differential diagnosis with focal organized pneumonia (FOC). Methods: the clinical and MSCT data of 58 cases of SPLC and 58 cases of FOP confirmed by pathology were retrospectively analyzed. The differences of MSCT signs and enhancement degree between them were compared, and the effectiveness of diagnosis of SPLC with the degree of enhancement was analyzed. Results of 58 cases of SPLC, 42 cases were round or round, 16 cases irregular, 46 cases with clear boundary, 12 cases with blur, 33 cases with deep lobes, 7 cases with superficial lobes, 8 cases with long burr, 37 cases with short burr, 19 cases with spinous process, 8 cases with halo sign and 6 cases with vacuole. Bronchial inflation sign (n = 17), necrosis (n = 7), pleural indentation (n = 34), pleural thickening (n = 6), vascular cluster sign (n = 20) (n = 20), round or round (n = 20), irregular shape (n = 38), clear boundary (n = 19), blur (n = 39), deep lobulation (n = 11). Superficial lobes in 8 cases, long spurs in 32 cases, short spurs in 9 cases, spinous processes in 11 cases, halo sign in 21 cases, vacuoles in 11 cases, bronchial inflation sign in 13 cases, necrosis in 10 cases, pleural depression in 11 cases, pleural thickening in 42 cases, vascular bundle sign in 18 cases. By chi-square test, two groups of morphologies, boundary, deep lobes, long burr, short burr, halo sign, pleural depression sign, were found. There was significant difference in pleural thickening in 58 cases of SPLC. Among the 58 cases of SPLC, 36 cases showed nodular homogeneous enhancement and 17 cases showed uneven patch enhancement. 5 cases showed mild or no enhancement. There was significant difference in the degree of enhancement between the two groups. The positive likelihood ratios of grade 鈪，
