Müllerian duct cyst: ultrasonographic and computed tomographic spectrum.

A Müllerian duct cyst (MDC) is the persistent remnant of the Müllerian duct. Reports of symptomatic cases are rare, signs and symptoms include perineal pain, dysuria, infertility, hematuria and genital inflammation. The prevalence of MDC has been previously reported as 4% of newborns and 1% in adult males. Herein we report six cases encountered in the past year. Our detection percentage was 1% and is compatible with the reported values. The imaging evaluation of symptomatic and asymptomatic patients with MDC is discussed as well as the apparent discrepancy between the number of previously reported cases and the reported prevalence.
