The importance of PET/CT in the evaluation of patients with Ewing tumors.

Guimarães JB, Rigo L, Lewin F, Emerick A - Radiol Bras (2015 May-Jun)

Bottom Line: The effective evaluation for the treatment of patients with Ewing tumors depends on the accuracy in the determination of the primary tumor extent and the presence of metastatic disease.The present study aimed at discussing the use of PET/CT as a tool for staging, restaging and assessment of therapeutic response in patients with Ewing tumors.Abstract available from the publisher.

ABSTRACT
The effective evaluation for the treatment of patients with Ewing tumors depends on the accuracy in the determination of the primary tumor extent and the presence of metastatic disease. Currently, no universally accepted staging system is available to assess Ewing tumors. The present study aimed at discussing the use of PET/CT as a tool for staging, restaging and assessment of therapeutic response in patients with Ewing tumors. In spite of some limitations of PET/CT as compared with anatomical imaging methods, its relevance in the assessment of these patients is related to the capacity of the method to provide further physiological information, which often generates important clinical implications. Currently, the assessment of patients with Ewing tumor should comprise a study with PET/CT combined with other anatomical imaging modalities, such as radiography, computed tomography and magnetic resonance imaging.

PET/CT image of a 13-year-old female patient diagnosed with Ewing’s sarcoma. Oneobserves expansile lytic lesion affecting particularly the left ischiopubic ramus,with rupture of the bone cortex and soft tissue components compromising theinternal obturator and adductor magnus muscles, showing glycolytic hypermetabolism(SUV max = 2.1). No other lesion was detected with the method.
