Sarcoma de Ewing Primário da Pleura num Jovem Adulto

Primary pleural Ewing sarcoma is a very rare entity with only sporadic cases reported in the literature. It is characterized by a high degree of malignancy, a poor prognosis, and difficulty in early diagnosis, since it has no specific clinical manifestations or characteristic imagiological features. The authors present a well-documented case of primary pleural Ewing sarcoma in a 20-year-old female, including chest X-ray, computed tomography and positron emission tomography findings.
