Introduction
Isolated retrovesical hydatid cyst is extremely rare. We report on 4 cases of retrovesical hydatid cyst treated at our center in the past 14 years.
Section snippets
Methods
All of the 4 patients were male, aged 55, 67, 63 and 28 years. Two of them complained of compressive syndrome (frequency, nucturia and urgency), other one has a chief complaint of bladder outlet obstruction that led to urinary retention. The last one was asymptomatic and diagnosed accidentally in a patient with a past history of leiomyoma of intestine 18 years ago. A serological test for hydatid cyst has been done in three cases, the result for all of them was positive. Computerized tomography
Results
Three symptomatic patients became asymptomatic after operation and pathologic test revealed the hydatid cyst lesion.
Conclusion
Isolated retrovesical hydatid cyst is extremely rare, but in endemic areas we must propose hydatid cyst lesions in differential diagnosis of pelvic cystic masses.
