Four neonates with giant ovarian cysts: difficulties in diagnosis and decision making process

Objective: Ovarian cysts compose most of the intraabdominal cysts in fetal period. Most of them regress spontaneously at intrauterine or postnatal period. The cysts that are complicated and do not regress are excised generally. Methods: Here we report a case series that consists of four newborns having giant (≥10 cm) ovarian cysts. All of the patients were term infants and followed for ovarian cysts in intrauterine period. Results: Patients were operated on 5, 11, 28, 47th days, respectively. Three patients had unilateral cysts (two right, one left) and one had bilateral cysts. One of the four patients had bilateral ovarian cysts, 100 × 95 mm in diameter on the left and 50 × 55 mm on the right, which was torsioned. Conclusion: The risk of complications is higher in bilateral cysts even they are smaller, and early surgical intervention should be done to these patients. During the operation of one of the patients, we detected the cyst at the opposite side that was shown by ultrasonography. Since the size of the mass is large, detecting the correct origin of the cyst is important for the selection of appropriate surgical approach.
