case_images: Computed tomography findings on admission. Contrast-enhanced coronal abdominal computed tomography showed a left 5.7 cm adrenal mass (red dots) and a large retroperitoneal hemorrhage.

case_images: Abdominal computed tomography revealed a left 5.7 cm adrenal mass with a large retroperitoneal hemorrhage (Figure 1), and the patient was transferred to our hospital for multidisciplinary treatment.
case_images: Change in imaging findings. (a) Contrast-enhanced axial computed tomography on admission indicated a left adrenal mass and a large retroperitoneal hemorrhage (red dots). (b) T1-weighted magnetic resonance imaging after a month discharge showed tumor shrinkage of a left adrenal mass and the reduction of hematoma (red dots). (c) Plain axial computed tomography three months after discharge indicated a 2.8 cm left adrenal mass and hematoma (red dots). (d) T1-weighted magnetic resonance imaging five months after discharge showed even more tumor shrinkage and the reduction of hematoma (red dots).

case_images: The tumor sizes were 3.1, 2.8, and 1.3 cm one month, three months, and five months after discharge, respectively (Figure 2).
case_images: Time course of clinical data. Blood pressure was well controlled with a significant decrease in plasma levels of catecholamines as the tumor size decreased after TAE. MN, levels of plasma metanephrine; NMN, levels of plasma normetanephrine.

case_images: Tumor shrinkage prompted us to resect the tumor laparoscopically (Figure 3).
case_images: Histopathological findings of the resected adrenal gland. (a) The cut surface of the tumor. The left adrenal tumor (a double-headed yellow arrow) measured 13 mm x 12 mm x 11 mm. (b) The section showed the large and irregular cell nest arrangement of tumor cells (hematoxylin and eosin x 400). (c) The brown staining showed the expression of chromogranin A in the tumor x 200.

case_images: Pathological findings confirmed the diagnosis of an adrenal pheochromocytoma (Figure 4).
