背景:囊性包虫病,一种由细粒棘球蚴幼虫引起的人畜共患疾病,主要影响肝脏和肺,人类充当意外宿主。
方法:我们在放射学和影像学系的回顾性研究,尼扎姆医学科学研究所,包括187例组织病理学或血清学证实的病例。呈现的平均年龄为49.4岁。
结果:肝脏受累最为普遍,占病例的83.4%(n=156),其次是其他器官如肠系膜的零星受累,脾,脾胰腺,丘脑,肾,肺,脊柱,还有网膜.影像学上观察到的特征性诊断特征包括33%的病例中的周围钙化,内隔25%(n=47),15%(n=29)的致密钙化,6%(n=11)的子囊肿,和漂浮膜在5%(n=10)。在肝脏病变中,90%(n=141)显示单叶受累。值得注意的是,78%(n=110)的病变仅限于右叶,21%(n=30)到左叶,1%(n=1)到尾状叶。受影响最大的肝段是VIII段,而最不常见的是I段(尾状叶)。在13%(n=25)的肝包虫病病例中发现了并发症。
结论:我们的研究结果强调了颗粒大肠杆菌感染的全身性,它可以影响身体的各个器官。它还说明了成像为及时准确诊断包虫病提供的宝贵见解。
BACKGROUND: Cystic echinococcosis, a zoonotic disease caused by the larval form of Echinococcus granulosus, predominantly affects the liver and lungs, with humans acting as accidental hosts.
METHODS: Our retrospective study at the Department of Radiology and Imageology, Nizam\'s Institute of Medical Sciences, included 187 histopathologically or serologically proven cases. The mean age of presentation was 49.4 years.
RESULTS: Liver involvement was most prevalent, accounting for 83.4% (n=156) of cases, followed by sporadic involvement of other organs such as the mesentery, spleen, pancreas, thalamus, kidney, lung, spine, and omentum. Characteristic diagnostic features observed on imaging included peripheral calcifications in 33% of cases, internal septations in 25% (n=47), dense calcifications in 15% (n=29), daughter cysts in 6% (n=11), and floating membranes in 5% (n=10). Among hepatic lesions, 90% (n=141) were showing involvement of a single lobe. Notably, 78% (n=110) of lesions were limited to the right lobe, 21% (n=30) to the left lobe, and 1% (n=1) to the caudate lobe. The most affected hepatic segment was segment VIII, while the least common was segment I (caudate lobe). Complications were identified in 13% (n=25) of cases of hepatic hydatidosis.
CONCLUSIONS: The findings of our study emphasize the systemic nature of E. granulosus infection which can affect various organs in the body. It also illustrates the invaluable insights imaging provides for timely and accurate diagnosis of hydatid disease.
