Hydatic cyst is a parasitic disease caused by the larvae of Echinococcus granulosus. In the study, the aim is to evaluate the relation between serology and grow-up time in atypically localized cysts.
Retrospectively, all the patients with hydatic disease between December 2004 and May 2012 were screened from the hospital database. Hydatic cyst localization other than the liver and lungs were accepted as atypical localization.
There were 325 patients with a diagnosis of hydatic disease. Most common localizations of the cysts were the liver (72.8%) and lungs (21%). Atypically localized cyst rate was 6.4% (n: 21). The most common atypical localization was the spleen (2.4%). 80.9% of atypically localized cysts were primary cases. In 3 cases with primary intramuscular hydatic cyst and 2 cases with primary subcutaneous hydatic cysts, serology was negative.
The relation between the hydatid cyst and the host is the main factor in serological tests and grow-up time. In tissues with a weaker cellular immunity like muscle and subcutaneous tissue, serology tends to be negative and grow-up time to be faster. In atypically localized cysts,hematogenous dissemination cannot explain the pathogenesis fully. Therefore, lymphatic dissemination should be kept in mind.
包虫囊肿是由细粒棘球绦虫幼虫引起的一种寄生虫病。本研究旨在评估非典型定位囊肿的血清学与生长时间之间的关系。
回顾性地从医院数据库中筛选出2004年12月至2012年5月期间所有患有包虫病的患者。除肝脏和肺以外的包虫囊肿定位被视为非典型定位。
共有325例被诊断为包虫病的患者。囊肿最常见的定位是肝脏（72.8%）和肺（21%）。非典型定位囊肿的发生率为6.4%（n = 21）。最常见的非典型定位是脾脏（2.4%）。80.9%的非典型定位囊肿为原发性病例。在3例原发性肌肉内包虫囊肿和2例原发性皮下包虫囊肿病例中，血清学检查为阴性。
包虫囊肿与宿主之间的关系是血清学检测和生长时间的主要因素。在肌肉和皮下组织等细胞免疫较弱的组织中，血清学往往呈阴性，生长时间往往较快。在非典型定位的囊肿中，血行播散不能完全解释其发病机制。因此，应考虑淋巴播散。
