Pelvic lymphangiomas are rare among lymphangiomas. Incomplete resection often causes recurrence of the lymphangioma, and it is sometimes difficult to extirpate the lesion without complications. A 7-year-old boy presented with fever and painful urination. Ultrasonography and abdominal computed tomography (CT) with contrast enhancement revealed a huge cystic lesion occupying the pelvic cavity and a dilated right renal pelvis and ureter. The size of the cystic lesion was 10 × 7 × 11 cm. Urography revealed a narrow portion in the prostate bulb urethra. Cytological examination revealed that the aspirated fluid was lymphocyte-predominant. On the basis of these findings, the patient was diagnosed as having pelvic lymphangioma. We attempted to perform laparoscopic complete resection, but performed laparoscopic fenestration instead because the adhesion between the dorsal cyst and the prostate was very firm. We resected the cyst wall as much as possible, and covered the residual cyst lumen with a polyglycolic acid (PGA) sheet and fibrin glue spray. The postoperative course was uneventful, and the patient was discharged on the 14th postoperative day. This patient has been followed up for 3 years without recurrence and relapse.
