Figure

• 

  Figure 1. Precontrast views in the initial computed tomography. (A) Retroperitoneal hemorrhage was infiltrated in the left retroperitoneum. (B) A huge mass was not distinguished from the hematoma in the left retroperitoneum.

• 

  Figure 2. Postcontrast views in the initial abdominal computed tomography. (A) There were several extravasated lesions near the left kidney. (B) Some arteries were supplying to the paraganglioma.

• 

  Figure 3. Postcontrast coronal view in the initial abdominal computed tomography: adjacent hemorrhage is masking the perirenal mass; therefore, it is difficult to distinguish from retroperitoneal hematoma.

• 

  Figure 4. Gross finding of the paraganglioma. There is a lobulated brown solid mass with hemorrhage (arrow) in the soft tissue.

• 

  Figure 5. H&E stain. (A) There is a lobulated solid mass with hemorrhage in the soft tissue (×1.25). (B) Histology revealed an alveolar pattern with nest of neoplastic cells surrounded by vascularized connective-tissue septa (×200). Nests outlined by sustentacular cells (arrow). Cells have finely granular basophilic or amphophilic cytoplasm. There was no necrosis.

• 

  Figure 6. Immunohistochemical staining. Staining was positive for (A) chromogranin A (×200) and (B) synaptophysin (×200).
