| There was no significant lymphadenopathy of the pelvic and retroperitoneal lymph nodes. |
| Computed tomographic scans of the chest, abdomen, and pelvis revealed hepatosplenomegaly and several small retroperitoneal lymph nodes. |
| These findings strongly support the origin of the tumor from heterotopic retroperitoneal rests of the adrenal gland. |
| Pulmonary complications, such as pleural effusion, result from retroperitoneal transudation of fluid from the swollen pancreas. |
| Primary retroperitoneal tumors may attach to the renal capsule or invade the kidney and, therefore, appear clinically as a primary renal tumor. |
| A retroperitoneal lesion was dissected that appeared to be an abnormally large tail of the pancreas. |
