Cystic echinococcosis, a zoonotic disease caused by the larval form of , predominantly affects the liver and lungs, with humans acting as accidental hosts.
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.
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.
The findings of our study emphasize the systemic nature of 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.
囊型包虫病是由细粒棘球绦虫幼虫引起的一种人畜共患病,主要影响肝脏和肺脏,人类为偶然宿主。
我们在尼扎姆医学科学研究所放射学与影像科进行的回顾性研究纳入了187例经组织病理学或血清学证实的病例。就诊时的平均年龄为49.4岁。
肝脏受累最为常见,占病例的83.4%(n = 156),其次是肠系膜、脾脏、胰腺、丘脑、肾脏、肺脏、脊柱和网膜等其他器官的散在受累。影像学观察到的特征性诊断表现包括33%的病例有周边钙化,25%(n = 47)有内部间隔,15%(n = 29)有致密钙化,6%(n = 11)有子囊,5%(n = 10)有漂浮膜。在肝脏病变中,90%(n = 141)表现为单叶受累。值得注意的是,78%(n = 110)的病变局限于右叶,21%(n = 30)局限于左叶,1%(n = 1)局限于尾状叶。受影响最严重的肝段是Ⅷ段,而最不常见的是Ⅰ段(尾状叶)。13%(n = 25)的肝包虫病病例出现了并发症。
我们的研究结果强调了感染的系统性,其可影响身体的各个器官。这也说明了影像学对于包虫病及时、准确诊断所提供的宝贵见解。
