case_images: CT imaging at 7 months (Figure 2) and 9 months (Figure 3) after surgery confirmed no renal recurrence and stable retroperitoneal and lung metastasis, with positive regional and distant recurrence. Figure 3 shows the mediastinal and right adrenal recurrence with a new development in the left adrenal nodule.
case_images: Mediastinal recurrence with pericardial effusion, bilateral adrenal and right intraperitoneal recurrences (upper image). Right adrenal recurrence with a new development of left adrenal nodule (lower image).
