肺淋巴管肌瘤病的高分辨率CT表现

目的 通过总结肺淋巴管肌瘤病的ＨＲＣＴ表现,讨论其诊断和鉴别诊断。方法 ３例均为女性,年龄为２４,２８和６９岁,其中６９岁患者合并右下肺腺癌。ＨＲＣＴ扫描技术包括１．５ｍｍ层面,骨重建算法,１４０ｋＶＰ和１４０－１７０ｍＡ,结果 ＨＲＣＴ均呈两肺多发,边缘清楚的薄壁囊状影,直径几毫米与２ｃｍ,囊壁从陷约可见至１ｍｍ厚,这些囊状影无外周或中心,上肺或下肺分布差异。

HRCT of Pulmonary Lymphangiomyomatosis

Objective　To describe the HRCT findings oflymphangiomyomatosis and discuss the diagnosis and differential diagnosis of this disease.Methods　Three patients were all women. The ages were 24,28 and 69 years old. The oldestpatient was proved by surgery with lymphangiomyomatosis and right lower lobeadenocarcinoma. The technique of HRCT scans of chest included 1.5mm collimation,bonealgorithm reconstruction,140kVP and 140～170mA. Results　HRCT scans showed multiple,well-defined and thin walledcysts imaging in all three cases. The cystic air spaces ranged in diameter from a fewmillimeter to 2 cm. The walls of cysts range being faintly perceptible to near 1mm inthickness. There was no peripheral/central or upper lobe/lower lobe preponderance of thecysts. Bilateral pleural effusions were present in one case. A lung mass was showed in onepatient. Conclusion　HRCT is valuable in diagnosis and differential diagnosisof pulmonary lymphangiomyomatosis.
