Ovarian fibrothecoma in a 15-year-old girl: A rare case report.

Ovarian fibrothecomas are rare benign tumors typically found in middle-aged women. This report presents a case of a 15-year-old girl with an irregular menstrual cycle and a left lateral uterine mass, ultimately diagnosed as an ovarian fibrothecoma. This case highlights the diagnostic challenges posed by fibrothecomas in younger patients, as they may mimic malignant ovarian tumors on imaging. Magnetic resonance imaging (MRI) findings, surgical intervention, and pathological examination confirmed the diagnosis. This case emphasizes the importance of accurate imaging and multidisciplinary approaches in managing such ovarian masses in adolescents.
