Abstract

Large ovarian cysts, regardless of whether benign or malignant, are uncommon and pose significant challenges in their management. This report discusses an adolescent diagnosed with a giant ovarian serous cystadenoma associated with a multifollicular ovarian morphology. A 17-year-old female patient was referred to us by a pediatrician due to abdominal distention and hirsutism. The physical examination showed that the patient reached Tanner Stage 5 development, indicating full maturity. There was noticeable abdominal distention and no organomegaly. Laboratory tests were unremarkable. Abdominopelvic ultrasonography and computed tomography were reported as a large cystic structure with thick walls and no septations, measuring 31.8×24.9×12.1 cm, possibly originating from the right ovary. The cyst was completely excised by laparotomy, while the ovarian tissue was preserved. It was observed that both ovaries had a multifollicular structure. Histopathological examination of the cyst was reported as a serous cystadenoma, which is a benign ovarian tumor. The latest follow-up of the patient was at six months after surgery, and the course of the follow-up was uneventful. The patient’s follow-up is still ongoing. In childhood and adolescence, ovarian masses are mostly benign regardless of their size, and ovarian-sparing surgery should be considered the first treatment option.
