Ovarian Tumors in Children: Pearls and Pitfalls
Purpose or Case Report: To describe the most frequent imaging findings of ovarian tumors in pediatric patients through different imaging methods (ultrasound, computed tomography and magnetic resonance imaging), in order to help in the differential diagnosis between benign from malignant pathology.
Methods & Materials: Medical records and imaging studies were reviewed in the period between January 2014 and August 2019. Forty-three patients with imaging studies compatible with ovarian tumor were included, 41 were confirmed by the anatomopathological study and 2 corresponded to other pathologies (ovarian torsion simulating ovarian mass and appendicular plastron with ovarian involvement, respectively).
Results: Patients age ranged from 2 months to 17 years old. Median age was 11.4 years. An abdominal mass was the most frequent clinical manifestation. The most frequent diagnosis was mature teratoma (24.4% of patients), followed by dysgerminoma (19.5%) and immature teratoma (17%). Other diagnosis were mucinous cystoadenoma, serous cystoadenoma, fibroma, Sertoli Leydig cell tumors, mixed germinal tumor, granulose cell tumor, small cell carcinoma, and ovarian fibroma. 11.6% of the patients had a tumor associated syndrome, and 16.2% had distant metastases or peritoneal implants.
Conclusions: We highlight the clinical-radiological challenge in the diagnosis of ovarian tumors in pediatric patients, due to their low frequency and nonspecific clinical manifestations. It is essential for the radiologist to learn about the imaging findings and their correlation with histological types, in addition to serum tumor markers for differential diagnosis. This is important for choosing the best surgical treatment in every case, emphasizing on minimally invasive techniques in this age group.
