Left renal Ewing's sarcoma: A case study and a review of imaging literature

Figures

• 

  Fig.1. Abdominopelvic CT; there is a huge retroperitoneal, heterogeneously enhancing, solid-cystic mass, originating from left kidney, measuring 164 × 143 × 108 mm. The mass has occupied most of the left upper abdominal cavity, crossing the midline and displacing small bowel loops. There is no accompanying lymphadenopathy or renal vein tumor thrombosis. CT, computed tomography.

• 

  Fig. 2. The sagittal view of tumor in abdominal CT. The upper limit of tumor is at the level of pancreatic body. The lower limit of tumor is at the level of midpart of left kidney. The tumor mostly grows anteriorly with exophytic pattern. The boundary of the tumor is shown with the white arrow. CT, computed tomography.

• 

  Fig. 3. Coronal view of abdominal CT. The upper limit of tumor is at the level of pancreatic body. The lower limit of tumor is at the level of midpart of left kidney. The tumor mostly grows anteriorly with exophytic pattern. The boundary of the tumor is shown with the white arrow. CT, computed tomography.

• 

  Fig. 4. The pulmonary spiral CT indicating noncalcified solid nodules randomly distributed in both lung fields and in the left upper lobe segments adjoining segmental bronchus. Also a few subpleural nodules in right lung with 9 mm longitude were accounted as the largest. CT, computed tomography.

  Fig. 5. Low power microscopic view, indicating sheets of monotonous small round cells nuclei with several mitotic; fine chromatin, and indistinct cytoplasm figures.
