The renal hydatid cyst: report on 4 cases

Abstract

The hydatid cyst is a frequent pathology in Morocco. All localizations are possible. However, renal hydatid cyst is still rare; it constitutes about 2.5 % of all localizations. We report 4 cases admitted at the Department of Pediatric Surgery of the University Hospital of Fes in the period running from February 2004 to January 2008. The four patients were of ages ranging from 8 to 11 years old. Two of them had double localization in the kidney and liver. The imaging was the diagnostic tool of choice. The patients benefited from surgical treatment; two were treated using standard surgery while laparoscopic surgery was used in the next two. Anti-parasitic medication was associated in the post-surgery stage for a period of six months. The evolution was good for all the patients.

A Five-Year-Old Child with Renal Hydatidosis

“…3 This finding was reflected in a cohort of 38 children given a diagnosis of hydatidosis and treated in our department over the past 13 years; three patients were found to have renal cysts. 4 Symptoms of the disease are related to the size of the cyst, which compresses adjacent structures, may rupture and become infected, or release content into neighboring body cavities.…”

“…Four days later, the patient had a fever and abdominal pain. Blood tests showed a leukocyte count of 17,700 cells/mm 3 with 78% neutrophils (13,806 cells/ mm 3 ) and normal renal and hepatic function. The patient was hospitalized because of the assumption of a bacterial superinfection of the cyst, and antibiotic treatment with clindamycin and cefotaxime was started.…”

“…Microscopy showed that the cyst contained a large number of protoscolices (Figure 2), confirming the clinical diagnosis of hydatidosis. Laboratory tests after surgery showed significant eosinophilia (3,000 cells/mm 3 ), which resolved within 30 days, and an indirect hemagglutination test showed a positive result (titer = 1:512).…”

A Kidney Hydatid cyst with No Conclusive Diagnostic Radiologic Evidence: A Case Report

“…Sonography is the first radiologic investigation that is noninvasive, sensitive, available, reliable, and inexpensive (3,10 easier than sonography does with high sensitivity and accuracy (10). In our case, sonography and CT scan did not show any evidence of daughter cyst, calcification, or other radiologic signs in favor of hydatid cyst diagnosis.…”

“…Although all localizations are possible, renal hydatid cyst is still rare (3). Hydatid cyst rarely is seen after 40 years of life.…”
