La presencia de un sangrado uterino anormal en mujer postmenopáusica y crecimiento anormal de masa uterina son datos de alta sospecha. El diagnóstico es un desafío al ser fácilmente confundible con el leiomioma benigno y adenomiosis. Los estudios de imagen ofrecen la información adecuada para diagnóstico, planificación quirúrgica y pronóstico.  Presentación del caso:  Mujer de 38 años, gesta 2, partos 1, cesárea 1. Inicia su padecimiento dos meses con ocho días después de una cesárea, con presencia de masa pélvica palpable, indolora y sangrado transvaginal anormal. En exploración física, se documenta tumoración palpable no dolorosa en región pélvica de 15 cm, sólida, irregular, móvil, con peloteo lateral y anterior hacia la cicatriz umbilical. Estudios de imagen: ultrasonido pélvico, resonancia magnética, tomografía abdominal computada trifásica y PET-CT de cuerpo entero con 18-FDG. Diagnóstico: leiomiosarcoma uterino. Tratamiento quirúrgico.  Conclusión:  El abordaje diagnóstico debe ser sistemático dado que es un tumor poco frecuente y agresivo y no en vano puede ser confundido con una patología benigna. Esto permite una mejor planificación terapéutica preoperatoria.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract:  Introduction:  Uterine leiomyosarcoma is a malignant neoplasm of the smooth muscle of the uterine wall, with low survival and high mortality. Abnormal uterine bleeding in postmenopausic women and abnormal growth of uterine mass are highly suspected data. Diagnosis is challenging as it is easily confused with benign leiomyoma and adenomyosis. Imaging studies offer useful information for diagnosis, surgical planning and prognosis.  Case presentation:  38 year old female, G2, P1, C1. Cesarean section three months prior to diagnosis. She began her current condition two months and eight days after her cesarean section, referring a painful palpable pelvic mass and abnormal transvaginal bleeding. Physical examination: her vital signs are stable. A palpable tumor in pelvic region of 15 cm, solid, irregular, mobile with lateral and anterior racking towards the umbilical scar, without pain on palpation was documented. Imaging studies: pelvic ultrasound, MRI, triphasic abdominal tomography and whole body PET-CT with 18-FDG. Diagnosis: uterine leiomyosarcoma. Surgical treatment.  Conclusion:  The diagnostic approach must be systematic since it is a rare and aggressive tumor and not in vain can it be confused with a benign pathology. This allows for better preoperative therapeutic planning.]]></p></abstract>
