{Reference Type}: Case Reports {Title}: Mature cystic teratoma overlapping with giant serous cystadenoma of the ovary: A case report. {Author}: Grisales-Gallo JE;Salinas-Castro KJ;Nasner D;Toro-Gutiérrez JS; {Journal}: Radiol Case Rep {Volume}: 19 {Issue}: 1 {Year}: 2024 Jan 暂无{DOI}: 10.1016/j.radcr.2023.10.030 {Abstract}: Ovarian lesions represent a diagnostic challenge for the radiologist and should be approached according to the patient's age, menstrual cycle, and imaging characteristics. These lesions can be cystic, mixed, or solid-predominant structures. Generally, the occurrence of benign lesions surpasses that of malignant ones at a ratio of 3:1. However, within infantile and juvenile age groups, this becomes an infrequent occurrence, making up only about 5% of ovarian tumor cases. This case report sheds light on a unique scenario involving a pediatric patient who harbored 2 benign tumors simultaneously: a mature cystic teratoma and a serous cystadenoma.
