Müllerian duct cyst is generally thought a very rare disease except in patients with sexual development disorders, such as hypospadia. In Japan, only 5 cases in normal males are in the literature. But the detection rate of this anomaly at autopsy was 0.7 to 1.0%.
We examined ultrasonically the prostates of 660 patients by intracorporeal electronic linear scanning during the last 4 years and 4 months, and found out 7 cases (1.1%) which demonstrated cystic image (1.5 to 3.0cm. in diameter) in the posterior midline portion of the prostate in echogram.
Four cases (0.6%) of them whose complaints were due to BPH and/or prostatitis underwent trans-perineal or transrectal ultrasonically guided cyst puncture and samll-sized cystograms could be obtained in all cases by radio-contrast medium injection.
The appearances of echogram and cystogram with retrograde urethrogram enabled us to diagnose them all Müllerian duct cyst and TUR was done in 1 case.
Müllerian duct cyst shows pear-shaped cystic image in the median lobe of the prostate in echogram and can be diagnosed by ultrasonically guided cyst puncture which is easily monitered by trasnrectal electronic linear scanning. The detection rate with ultrasound agreed with that at autopsy.
