Isolatedextra Hepatic and Extra Pulmonary Hydatid Cyst: Report of 33 Rare Cases - Abstract
Background: Hydatid disease is a parasitic infestation caused by Echinococcus granulosus and caused by the larval stage of the Echinococcus tapeworm and it primarily affects the liver and lung but involvement of other organs is also possible secondary to peritoneal seeding or hematogeneous dissemination. About extra hepatic and pulmonary hydatid cyst (EHPHC) there are not basic studies. we want to discuss this entity and review the literatures.
Materials and methods: A systematic retrospective review was performed for all extra hepatic and pulmonary hydatidcyst (EHPHC) patients treated in our province between 1990and 2016. Inclusion criteria in this study, was all patients with (EHPHC) organ involvement without simultaneously involvement liver and lung by hydatid cyst. Final diagnosis confirmed with pathologist. The patient’s records were studied for gender, age, site of involvement, diagnosis and results of treatment. All data was analyzed by using SPSS version 21.
Results: In this study record of 33 patients who were evaluated within this period, were reviewed. 21 patients were male and 12 patients were female. Age of patients was 25 to 56 years old. Hydatid cyst of spleen was the most common all of (EHPHC). Others were Kidney, pancreas, soft tissue and mediastinum. The most common tools for diagnosis was U/S and CT-scan. All patients with hydatid cyst of spleen underwent splenectomy. Others (EHPHC) underwent radical resection. Albendazole used in all patients just post operation. Outcomes of surgery were good and no recurrences were occurred.
Conclusion: Although liver and lung are the most commonly involved organs, in 10% of cases it occurs in other locations. Hydatid cysts should be included in the differential diagnosis of any cystic mass of all organs in body, especially in endemic regions. Total remove of the cyst component without any spillage is the best treatment option.
