背景:包虫病,也被称为包虫病,是由棘球蚴幼虫引起的人畜共患寄生虫感染。它在世界各地的各个地区都很流行,特别是在南美洲南部国家的农村地区,中亚,中国,非洲的部分地区,地中海,以及中东部分地区。该疾病主要影响肝脏(60-70%的病例)和肺部(10-25%的病例),但它可以涉及任何器官,包括大脑,骨头,很少在骨盆区域,从我们的案例报告中可以看出。包虫病通常在原发感染的早期阶段遵循无症状的过程,并且可能持续数年甚至永久。如果出现症状,它们取决于各种因素,比如数字,尺寸,和位置等因素。通常,包虫病表现为非特异性症状。常见症状包括腹痛,肝肿大,以及囊肿破裂时的过敏反应。肝外腹内孤立性包囊是一个罕见的发现(6-11%)。
方法:在我们的例子中,一名70岁的亚洲白人男性右大腿疼痛放射到小腿,这是肝外腹内包虫囊肿的非典型表现。累及骨盆区域的原发性腹内包虫囊肿相对罕见,这类病例带来了诊断和管理方面的挑战。
结论:本病例报告强调了诊断和管理肝外腹内包虫囊肿的挑战,特别是在非典型的演讲中。结合临床评估,血清学研究,和成像技术有助于准确诊断。
BACKGROUND: Hydatid disease, also known as echinococcosis, is a zoonotic parasitic infection caused by the larvae of the Echinococcus tapeworm. It is endemic in various regions worldwide, particularly in rural areas of countries in southern South America, Central Asia, China, parts of Africa, the Mediterranean, and parts of the Middle East. The disease primarily affects the liver (60-70% of cases) and the lungs (10-25% of cases), but it can involve any organ, including the brain, bones, and rarely the pelvic region, as seen in our case report. Hydatid disease typically follows an asymptomatic course in the early stages of the primary infection and may remain so potentially for years or even permanently. If symptoms occur, they depend on various factors, such as the number, size, and location among other factors. Typically, hydatid disease presents with nonspecific symptoms. Common symptoms include abdominal pain, hepatomegaly, as well as anaphylaxis in case of cyst rupture.
Extrahepatic intra-abdominal isolated hydatic cyst is a rare finding (6-11%).
METHODS: In our case, a 70 year-old Asian white male presented with right thigh pain radiating to the lower leg, which is an atypical presentation for an
extrahepatic intraabdominal hydatid cyst. Primary intraabdominal hydatid cysts involving the pelvic region are relatively rare, and such cases pose diagnostic and management challenges.
CONCLUSIONS: This case report underscores the challenges in diagnosing and managing
extrahepatic intraabdominal hydatid cysts, particularly in atypical presentations. A combination of clinical evaluation, serological studies, and imaging techniques facilitates accurate diagnosis.
