A 16 year old boy reporting several months of hip pain, weight-loss, and fatigue presented to our institution after a pelvis radiograph ordered by his family physician showed concerning findings. MR imaging of his pelvis demonstrated a large heterogeneously enhancing mass arising from the right iliac wing causing significant mass effect on the pelvic organs and soft tissues of the buttocks. A percutaneous biopsy confirmed the diagnosis of Ewing sarcoma.
A staging CT of the chest was performed, demonstrating multiple lung metastases. In addition to this finding, there was multifocal bilateral nodular tumor thrombus propagating along multiple subsegmental pulmonary arteries, with a pseudo tree-in-bud morphology. Given their course, these metastatic deposits appeared endovascular in origin.

Ewing sarcoma is the second most common malignancy of bone with an incidence of approximately 200 cases per year in the United States in children under 20. Extraosseous Ewing sarcoma originating in the vagina is rare, with only 8 cases reported to date in the literature. These highly aggressive tumors require a more intensive treatment regimen compared to other vaginal masses like rhabdomyosarcoma. While the imaging findings are non-specific, awareness of this clinical entity can facilitate early diagnosis and appropriate treatment, which may improve prognosis. Read More
