【摘要】：目的探討肺部惡性局灶性磨玻璃密度結(jié)節(jié)(f GGO)在MSCT隨訪復(fù)查中的動(dòng)態(tài)征象變化特點(diǎn)。方法回顧性分析經(jīng)手術(shù)病理證實(shí)的32例36個(gè)惡性f GGO的CT征象,包括14個(gè)單純型磨玻璃密度結(jié)節(jié)(p GGO),22個(gè)混合型磨玻璃密度結(jié)節(jié)(m GGO),觀察對(duì)照其初診與術(shù)前CT在形態(tài)大小、內(nèi)部密度、邊緣形態(tài)及其周圍結(jié)構(gòu)等征象的動(dòng)態(tài)變化。結(jié)果術(shù)前CT征象比初診CT有明顯增多,包括形態(tài)發(fā)生改變,基本呈圓形/類圓形,境界變清楚,平均大小增加15%(2.1 mm),8個(gè)p GGO出現(xiàn)實(shí)性成份,22個(gè)m GGO實(shí)性成份增加,新增"分葉征"13個(gè),"毛刺征"11個(gè),"空泡征"3個(gè)、"支氣管充氣征"2個(gè),"胸膜凹陷征"3個(gè)、"血管集束征"5個(gè),局限性肺氣腫2個(gè)。結(jié)論肺部惡性f GGO的各個(gè)CT征象隨時(shí)間經(jīng)常發(fā)生變化,特別是實(shí)性成份的出現(xiàn)/增加,"分葉征"、"毛刺征"、"胸膜凹陷征"的出現(xiàn),認(rèn)識(shí)這些征象的變化,有助于及時(shí)做出正確的判斷。
[Abstract]:Objective to investigate the dynamic features of malignant focal ground-glass density nodules (f GGOs) in the lung during MSCT follow-up. Methods CT features of 36 cases of malignant f GGO proved by surgery and pathology were retrospectively analyzed. There were 14 pure glass-density nodules and 22 mixed glass-density nodules. The size and internal density of primary and preoperative CT were observed and compared. Results the preoperative CT signs were significantly more than those of the newly diagnosed CT, including the morphological changes, which were basically round / round, and the boundary became clear. The average size increased by 15 ~ 2. 1 mm, 8 p GGO produced realistic composition, 22 m GGO solid component increased, 13 new "lobulation sign", "burr sign" 11, "vacuole sign" 3, "bronchial inflatable sign" 2, "pleural indentation sign" 3, "vascular cluster sign" 5. Conclusion the CT signs of pulmonary malignant f GGO often change with time, especially the appearance / increase of solid components, the appearance of lobulation sign, burr sign, pleural depression sign, and recognize the changes of these signs. It helps to make the correct judgment in time.
