【摘要】：目的探讨肺部恶性局灶性磨玻璃密度结节(f GGO)在MSCT随访复查中的动态征象变化特点。方法回顾性分析经手术病理证实的32例36个恶性f GGO的CT征象,包括14个单纯型磨玻璃密度结节(p GGO),22个混合型磨玻璃密度结节(m GGO),观察对照其初诊与术前CT在形态大小、内部密度、边缘形态及其周围结构等征象的动态变化。结果术前CT征象比初诊CT有明显增多,包括形态发生改变,基本呈圆形/类圆形,境界变清楚,平均大小增加15%(2.1 mm),8个p GGO出现实性成份,22个m GGO实性成份增加,新增"分叶征"13个,"毛刺征"11个,"空泡征"3个、"支气管充气征"2个,"胸膜凹陷征"3个、"血管集束征"5个,局限性肺气肿2个。结论肺部恶性f GGO的各个CT征象随时间经常发生变化,特别是实性成份的出现/增加,"分叶征"、"毛刺征"、"胸膜凹陷征"的出现,认识这些征象的变化,有助于及时做出正确的判断。
[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.
