Background
Cystic echinococcosis (CE) is a zoonosis caused by Echinococcus granulosus (sensu lato). It is a neglected tropical disease with a global distribution, affecting an estimated 2–3 million people globally. Official reporting systems in Spain lack information concerning imported cases and their country of origin.
Methods
This is a systematic review of the literature that was performed to obtain published cases of immigrant patients diagnosed with CE in Spain.
Results
From the 21 included articles, a total of 84 cases of CE imported into Spain were documented from 1995 to 2018, with an average age of 33.2 years. The main countries of origin of the patients were Morocco with 30 cases (35.7%), Romania with 12 cases (14.3%) and Peru with 8 cases (9.5%). The most involved organ was the liver (28 cases [33.3%]). We found discrepancies between the published cases of imported CE in Spain and those reported by official authorities.
Conclusions
This review of the literature shows the lack of information and clarity in the mechanisms of CE notification in Spain. The disparity between these systems and the cases documented in the literature highlights a failure or shortcoming of the current reporting system.

Introduction
Pericardial hydatid cyst comprises 7% of all cardiac hydatidosis, but its occurrence is concomitant with several life-threatening complications. This study is a review of the reported studies of pericardial hydatid cysts.
Methods
A systematic review of the published studies of pericardial hydatid cysts was conducted. The studies of cardiac hydatid cysts with the following properties were included: 1) The pericardium infection was confirmed by diagnostic modalities, surgical findings, or histopathology. 2) The case presentation was provided in the study. 3) The cyst (s) originally located or adhered to the pericardium and did not rupture into it from the other adjacent cardiac structures or organs.
Results
Overall, 106 studies were compatible with the inclusion criteria. Most of the cases (29.72%) were reported in Turkey, followed by India (18.24%). There was no gender predilection, and the age of the patients was distributed between 5 and 80 years old. The most common symptoms were chest pain (43%), and dyspnea (36%). Hydatid cysts were only found in the pericardium in 56% of cases and multiloculated in 44%. Surgery was the treatment of choice (87.8%), and cystectomy (72.3%) was the major technique of cyst removal. The total number of recurrences was 3 cases (2%). There was a significant correlation between recurrence and the history of hydatidosis. The mortality rate was 2.7%.
Conclusion
Pericardial hydatid disease is more common in subtropical regions. The definitive treatment of a pericardial hydatid cyst is surgery, mainly through a median sternotomy. A history of hydatidosis increases the likelihood of recurrence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
