We report the clinical value of FDG PET/CT imaging in a 57-year-old woman who was diagnosed with uterine leimyosarcoma 6 years ago. In a staging procedure, whole body FDG PET/CT discloses the presence of both local recurrence and remote metastases at widespread musculocutaneous sites, liver and femur. With its advantage of scanning the whole body in a single procedure, we propose the use of PET/CT imaging for the evaluation of patients with uterine leimyosarcomas, a tumor with a propensity for widespread hematogenous spread to unusual sites. Presentamos el valor clínico de la FDG PET/TC en una mujer de 57 años de edad diagnosticada de leiomiosarcoma uterino hace 6 años. En un estudio de estadificación, la FDG PET/TC descubrió la presencia tanto de recidiva local como de metástasis a distancia en localizaciones musculocutáneas, hígado y fémur. Por la ventaja de obtener imágenes del cuerpo completo, proponemos el uso de la PET/TC en la evaluación de pacientes con leiomiosarcoma uterino, un tumor con tendencia a la diseminación hematógena hacia localizaciones poco habituales.
