Abstract

We report firstly a case of mullerian duct cyst associated with bilateral ectopic opening vasa in 4 months old male infant in Korea. Presenting findings were the complaint of urinary retention, fever and lower abdominal mass. Ultrasonography and MRI of pelvis showed a monolocular 5 x 5 x 4cm sized cystic mass, which was located on the midline between the bladder and rectum. RGU and VCUG showed anterior displacement of bladder due to outside compression. Under the impression of mullerian duct cyst, surgical removal of cyst was performed by transvesical, transtrigonal approach because the large cystic mass produced hydronephrosis of left kidney and urethral diameter was smaller than that of our pediatric resectoscope(11Fr.) We performed ligation of the vas because the bilateral vasa entered into the cyst, directly. Microscopically mullerian duct cyst was lined by stratified squamous epithelium. Walthard cell nests, nuclear groove and vas tissue were also showed in mullerian duct cyst. In the course of follow-up, he has no urologic difficulty after the operation.
