Laparoscopic management of antenatally-diagnosed abdominal cysts in newborns

We report two newborns each detected to have a large intra-abdominal cyst on antenatal ultrasonography. Postnatal imaging confirmed presence of the cysts and showed a complex cyst with multiple septae in the first patient and evidence of bleeding in both. Laparoscopy performed on the 14th and 19th day of life, respectively, showed ovarian cysts with hemorrhage and torsion. The cysts were treated successfully by laparoscopic oopherectomy. Histopathology revealed an ovarian gonadoblastoma in the first patient and a simple cyst with calcification in the second. Both patients remain well at a follow up of six and four months. Laparoscopic treatment of antenatally detected cystic abdominal masses is a feasible option in the newborn.
