本文报告了２６例膈肌包虫囊肿的Ｘ线表现，均经手术病理证实，其Ｘ线表现分为单纯性包虫囊肿及破裂感染的包虫囊肿两类，单纯包虫囊肿表现为膈肌局限性膨出；带蒂的突向胸腔的卵园形阴影，及合并囊肿钙化。破裂感染的包虫囊肿表现为囊肿内“月牙征”，“水上百合”或“气液平”；合并胸膜及肺内感染或肺包虫囊肿，及类似单纯性胸腔积液。讨论了常规Ｘ线，ＣＴ，超声的影象诊断。并指出多数膈肌包虫囊肿位于右侧膈肌，约８倍于左膈，因此，左膈的一些病变，一般不应考虑包虫囊肿。
This article reports the X-ray findings of 26 cases of phleiial hydatid cyst, both confirmed by surgery and pathology, the X-ray findings were divided into simple hydatid cyst and ruptured infection hydatid cyst two categories, the simple hydatid cyst showed the limitations of the diaphragm Bulging; pedunculated to the chest cavity egg-shaped shadow, and calcification of cysts. Hydatid cyst rupture infection showed cyst “crescent sign”, “water lily” or “gas-liquid level”; combined pleural and pulmonary infection or hydatid cyst, and similar simple pleural effusion. Discussed the conventional X-ray, CT, ultrasound imaging diagnosis. And pointed out that the majority of diaphragm hydatid cysts in the right diaphragm, about 8 times the left diaphragm, therefore, some lesions of the left diaphragm, generally should not be considered hydatid cyst.
