The classical findings in hydatid disease caused by Echinococcus granulosus with liver or lung involvement are well known. However, diagnosing hydatid disease at unusual locations may be challenging because of variable imaging appearances depending on the host reaction. The purpose of this pictorial essay is to review the sonographic, CT, and MRI features of extrahepatic abdominal hydatid disease including intraperitoneum, retroperitoneum, diaphragma, bone, and soft tissue of the abdomen.
Extrahepatic abdominal hydatid lesions have nearly identical imaging features, including the presence of cyst wall calcification, daughter cysts, and membrane detachment. The combinations of radiologic and serologic tests especially in patients living in the endemic areas contribute to the diagnosis. Despite their rarity, being familiar with the spectrum of radiologic findings in these unusual sites is helpful to improve diagnostic accuracy.
细粒棘球绦虫所致肝或肺受累的包虫病的典型表现众所周知。然而，由于取决于宿主反应的影像学表现多样，在不寻常部位诊断包虫病可能具有挑战性。本文的目的是回顾肝外腹部包虫病的超声、CT和MRI特征，包括腹腔、腹膜后、膈肌、骨骼和腹部软组织。
肝外腹部包虫病变具有几乎相同的影像学特征，包括囊壁钙化、子囊和膜剥离。放射学检查和血清学检查相结合，尤其是对生活在流行地区的患者，有助于诊断。尽管这些病变罕见，但熟悉这些不寻常部位的放射学表现谱有助于提高诊断准确性。
