Introducción. Los abscesos tubo ováricos son poco frecuentes en la posmenopausia y se asocian con patologías ginecológicas benignas como endometriosis, pólipo endometrial o leiomioma uterino, y con patologías malignas como adenocarcinoma de endometrio, tumores malignos epiteliales y no epiteliales de ovario, carcinoma escamocelular de cérvix y adenocarcinoma de colon. Su presentación representa un reto diagnóstico y terapéutico para el médico.

Presentación del caso. Paciente femenina de 72 años, quien consultó por cuadro clínico de tres días de evolución consistente en dolor y distensión abdominal asociados a fiebre y síntomas urinarios irritativos y retención urinaria. Los exámenes de ingreso mostraron leucocitosis con neutrofilia y CA-125 en 222 U/mL. El ultrasonido y la resonancia magnética evidenciaron una masa retrouterina solido-quística de 15 cm. Ante sospecha de tumor versus absceso tubo-ovárico, se realizó biopsia dirigida por tomografía mediante la cual se encontró material purulento fétido. Se practicó laparotomía que confirmó masa pélvica retrouterina sólido quística con contenido purulento, adherencias y compromiso inflamatorio de las trompas uterinas. El resultado de patología informó fibroma ovárico y absceso tubo ovárico. La paciente evolucionó satisfactoriamente en el posoperatorio y en los controles posteriores.

Conclusiones. El caso reportado ilustra cómo, en ocasiones, un posible diagnóstico de carcinomatosis por cáncer de ovario puede ser realmente una patología benigna (absceso tubo ovárico) que responde bien a un tratamiento médico-quirúrgico. Las imágenes diagnósticas y los marcadores tumorales son de gran ayuda para diferenciar una patología ovárica maligna de un proceso benigno.

Introduction: Tubo-ovarian abscesses are rare in postmenopausal women. They have been associated with benign gynecological conditions such as endometriosis, uterine polyp or leiomyoma, and malignant diseases such as endometrial adenocarcinoma, epithelial and non-epithelial malignant ovarian tumors, squamous cell carcinoma of the cervix, and adenocarcinoma of the colon. Their presentation represents a diagnostic and therapeutic challenge for clinicians.

Case report: A 72-year-old female patient was admitted with a 3-day history of abdominal pain and distension, fever, irritative urinary symptoms and urinary retention. Lab tests on admission showed elevated white blood cells and neutrophils count, and CA-125 at 222 U/mL. Ultrasound and magnetic resonance imaging revealed a solid retrouterine cystic mass of 15 cm. Suspecting tumor versus tubo-ovarian abscess, a tomography-directed biopsy was performed, finding foul-smelling purulent material. An exploratory laparotomy was performed with intraoperative findings of solid-cystic retrouterine pelvic mass with purulent content, adhesions, and inflammatory involvement of the uterine tubes. Pathology reported ovarian fibroma and tubo-ovarian abscess. The patient evolved satisfactorily in the postoperative period and in the subsequent follow-up appointments.

Conclusions: The reported case illustrates how a possibility of ovarian cancer with peritoneal carcinomatosis can actually be a benign condition (tubo-ovarian abscess) that responds well to medical-surgical treatment. Diagnostic imaging and tumor markers are helpful in differentiating a malignant ovarian disease from a benign process.
