case_images: (A) The electrocardiogram showed ventricular tachycardia. (B) Electrocardiography on admission showing the waves of ST-segment elevation in leads I, II, aVF, and V2-V6. (C) Electrocardiography showed inverted T waves in leads I, II, III, aVF, and V2~6, and a prolonged QT interval. (D) Three months after surgery, T waves having slight changes were revealed.

case_images: T waves in leads I, II, III, aVF, and V2~V6 ( Figure 1C ). Moreover, his electrocardiogram ( Figure 1D ) showed that T wave changes slightly as confirmed by an outpatient follow-up.
case_images: (A-C) Emergency coronary angiography showed LAD emitted D1 have plaque formation and mild stenosis, but LCX have no obvious stenosis. (D) RCA have no significant abnormality.

case_images: Emergency coronary angiography ( Figure 2 ) did not show significant abnormalities.
case_images: (A-D) Abdominal plain CT: right retroperitoneal cystic solid space-occupying lesion (arrow). (E-F) Magnetic resonance image of the abdomen with gadolinium contrast showing a 9.0* 6.5 * 10.7 cm right adrenal mass (arrow). (G, H) The 3D model of the abdominal lesion (arrow).

case_images: Enhancement after abdominal plain scan and the 3D models showed the following ( Figures 3A - D, G, H ): there was a right retroperitoneal cystic solid space-occupying lesion, and it was complicated with bleeding or infection; adjacent to the retroperitoneal space, there were a small amount of exudative changes around the inferior vena cava and also fascia thickening. Magnetic resonance imaging (MRI) of the abdomen with gadolinium contrast showed the following ( Figures 3E, F ): there was a right retroperitoneal space-occupying lesion, the tumor with bleeding or infection was considered, and the tumor size was about 9.0 * 6.5 * 10.7 cm.
case_images: Macroscopic examination of the tumor (9 * 8 cm) showed areas of necrosis and hemorrhage of the right retroperitoneal.

case_images: The tumor was carefully separated from the surrounding tissue, and it was removed ( Figure 4 ).
case_images: Pathology and immunohistochemistry (A-H) showed HE staining of the tumor tissue (HE, x200), CgA (+), Syn (+), SF-1 (-), S-100 (+), CK (-), and vimentin (-), and the Ki-67 index was 2%.
