目的:观察肺包虫囊肿的CT表现,评价CT对本病的临床应用价值。材料和方法:回顾性地分析了17例经临床手术病理证实的肺包虫囊肿的CT表现。以10mm层厚。行平扫后增强扫描。结果:17例肺包虫囊肿中,单发12例,多发5例。共29个病灶。75％分布于肺边缘区域。破裂7例。感染9例。主要征像为园形或卵园形均匀的水样密度的囊性病灶。特征性的征象为囊壁上点状或细弧线形钙化;囊内多于囊的显示;破裂时的新月征、水上浮莲征、腔内蛇影征。继发感染时囊周片状炎性实变。结论:将CT应用于肺包虫囊肿的诊断能发现隐蔽区的病灶。定位准确。并能有效显示肺包虫囊肿的特征及并发症的表现,提高对本病诊断的准确性。正确指导临床治疗。
Objective: To observe the CT manifestations of hydatid cysts and evaluate the clinical value of CT in the diagnosis of this disease. MATERIALS AND METHODS: CT findings of 17 cases of hydatid cysts confirmed clinically and pathologically were retrospectively analyzed. With 10mm layer thickness. After the line scan enhanced scan. Results: In 17 cases of hydatid cysts, 12 cases were single and 5 cases were multiple. A total of 29 lesions. 75% distributed in the marginal area of the lungs. Rupture in 7 cases. Infection in 9 cases. The main signs of park-shaped or oval-shaped uniform water-like cystic lesions. Characteristic signs of cystic point on the wall or thin arc-shaped calcification; cystic more than the capsule shows; rupture of the crescent sign, float on the water levy, intracavitary serpentine. Secondary infection cystic lobe inflammatory consolidation. Conclusions: The diagnosis of pulmonary hydatid cyst can be used to detect lesions in the hidden area. Positioning accuracy. And can effectively show the characteristics of pulmonary hydatid cyst and the performance of complications, improve the accuracy of diagnosis of the disease. Correctly guide clinical treatment.
