【摘要】：目的探讨局灶性机化性肺炎的CT表现特征及其病理相关性。方法对20例经病理学证实的局灶性机化性肺炎患者的CT资料进行回顾性分析,并将病变的CT表现与相应的病理改变进行对照。结果 20例局灶性机化性肺炎中CT表现结节型8例,肿块型6例,浸润实变型6例。表现为圆形或类圆形7例,不规则形13例。边缘分叶7例,毛刺8例,尖角样改变7例。平扫密度均匀10例,密度不均匀10例。4例见空泡征,9例见充气支气管征,4例伴空洞,2例伴钙化。16例增强检查中,5例均匀强化,11例不均匀强化,其中9例内部可见无强化的坏死灶。16例与邻近胸膜有关系。与病理对照分析:明显强化区主要为炎性肉芽肿及较多炎细胞浸润部分,而病灶中央出现的无强化区为脓肿形成区域。结论局灶性机化性肺炎的CT表现多样,但有一定的特征性,在一定程度上可反映其病理特点,正确诊断可以避免不必要的手术。
[Abstract]:Objective to investigate the CT features and pathological correlation of focal organopneumonia (FOC). Methods the CT data of 20 patients with pathologically proved focal organized pneumonia were analyzed retrospectively, and the CT findings were compared with the corresponding pathological changes. Results among 20 cases of focal organized pneumonia, 8 cases were nodular type, 6 cases were mass type and 6 cases were infiltrative and solid type. They were round or round in 7 cases and irregular in 13 cases. There were 7 cases with marginal lobulation, 8 cases with spurs and 7 cases with sharp angle changes. There were 10 cases of homogeneous density in plain scan, 9 cases of vacuole sign in 10 cases of uneven density, 4 cases of bronchial sign of inflation and 2 cases of cavitation with calcification in 4 cases, and 11 cases of uneven enhancement in 5 cases of homogeneous enhancement and 11 cases of uneven enhancement. No enhancement necrosis was found in 9 cases. 16 cases were related to the adjacent pleura. Compared with pathology, the obvious enhancement area was mainly inflammatory granuloma and more inflammatory cell infiltration, while the non-enhanced area in the center of the lesion was abscess formation area. Conclusion the CT findings of focal organized pneumonia are various, but they have some characteristics, which can reflect the pathological characteristics to some extent and avoid unnecessary surgery.
