MRI Appearance of a Giant Ovarian Sero-mucinous Cystadenofibroma Mimicking Ascites. A Case Report and Brief Literature Review

Introduction: Giant ovarian cystadenofibromas are rare, mostly benign tumors. In the early stages, they are asymptomatic; however, as they grow in size, they begin to produce symptoms, most often due to the compressive effects they exert on surrounding structures. In the early stages, they are frequently diagnosed by ultrasonography, but complicated cases or cystadenofibromas that reach giant dimensions are ideally evaluated by magnetic resonance imaging (MRI) to establish a therapeutic surgical decision that is as safe as possible for the patient. Case report: We present the case of a 49-year-old perimenopausal patient without vaginal bleeding or other gynecological symptoms who presented to the hospital with abdominal pain and abdominal distension with increasing intensity. Ultrasound examination revealed the presence of a high volume of fluid in the abdomen, and MRI and histopathological examination confirmed the diagnosis of a giant left ovarian type III seromucinous cystadenofibroma. The patient was treated surgically, with favorable postoperative evolution. Conclusion: Giant cystadenofibromas are rare clinical entities that must always be considered in the differential diagnosis of an abdominopelvic pathology in middle-aged female patients and should ideally be investigated by MRI to accurately define their origin, characteristics, and local invasion.
