分析20例泡球蚴病(以下简称泡球蚴病)肺部侵犯,并按放射学的两类区分为Ⅰ或Ⅱ型。Ⅰ型呈多发性、小的、边界模糊、不规则的病变、局限于周围肺野而且发展缓慢;Ⅱ型位于右肺基底部呈各种改变。Ⅰ型来自血源性转移,而Ⅱ型系肝内病变穿透横膈所致。鉴别诊断:包括肿瘤及感染等,特别是囊性棘球蚴病,鉴别困难。仅Ⅰ型改变结合实验室所见及地理分布可得出诊断。(?)囊性棘球蚴病(或细粒棘球蚴病)因为广泛流行分布,已为临床学者及放射学家所熟知,而关于泡球蚴(多房性泡球蚴病)的报道仍是不多。棘球蚴囊肿与泡球蚴病二者生活发展周期均需变换宿主。通常仅肝脏受侵犯、而其他器官的侵犯不是经血行传播感染就是藉病变的直接扩展蔓延。通常包虫囊
Analysis of 20 cases of alveolar echinococcosis (hereinafter referred to as alveolar echinococcosis) lung invasion, and according to the two types of radiology is divided into Ⅰ or Ⅱ type. Type Ⅰ was multiple, small, fuzzy boundaries, irregular lesions, confined to the surrounding lung field and the slow development; type Ⅱ in the right lung base at the bottom of a variety of changes. Type Ⅰ from blood-borne metastasis, and type Ⅱ Department of intrahepatic lesions caused by the diaphragm. Differential diagnosis: Including tumors and infections, especially cystic echinococcosis, identification difficulties. Only type I changes combined with laboratory findings and geographical distribution can be diagnosed. (?) Cystic echinococcosis (or granulomatous echinococcosis) is well known to clinicians and radiologists for its widespread epidemic, and reports of cysticercosis (polyatomic alveolar echinococcosis) Still not much. Hydatid cyst and alveolar hydatid disease life cycle both need to transform the host. Often only the liver is infringed, and the invasion of other organs is not spread by bloodstream or by the direct spread of the disease. Usually hydatid cysts
