目的 :分析单发性假瘤的临床 X线表现 ,提高诊断及鉴别诊断水平。方法 :对手术切除、CT导引下肺穿刺活检证实的 2 4例肺炎性假瘤的临床、X线胸片及 CT片进行回顾性分析。结果 :在 2 4例肺炎性假瘤中 ,79% ( 1 9/ 2 4 )的肿块位于肺的外周 ,贴近胸膜面可伴有胸膜肥厚 ;75% ( 1 8/ 2 4 )的肿块边缘光滑规整 ,其内密度均匀 ;6 7% ( 8/ 1 2 ) CT增强值大于 6 0 Hu;CT导引下肺穿刺活检定性诊断率为 90 % ( 1 0 / 1 1 )。结论 :X线胸片和 CT是诊断肺炎性假瘤的主要方法 ,CT导引下肺穿刺活检定性诊断率高 ,可作为组织学诊断的首选方法。
Objective: To analyze the clinical X-ray findings of solitary pseudotumor and improve the diagnostic and differential diagnosis. Methods: The clinical, radiographic and radiographic CT findings of 24 cases of pneumonectatic pseudotumor confirmed by pulmonary biopsy under the guidance of CT were retrospectively analyzed. Results: Of the 24 cases of pulmonary inflammatory pseudotumor, 79% (19/24) of the tumor were located on the periphery of the lung. Pleural thickening was associated with the pleural surface. 75% (18/24) of the tumor had smooth edges The internal density was uniform. The enhancement of 6 7% (8/1 2) CT was greater than 60 Hu. The positive rate of CT diagnosis of lung biopsy was 90% (10/1). Conclusion: X-ray and CT are the main methods for the diagnosis of pulmonary pseudotumor. CT-guided qualitative diagnosis of lung biopsy can be used as the first choice for histological diagnosis.
