Primary hypertension in a postoperative paraganglioma patient: A case report

Figure 1 Computed tomography scan of paraganglioma. Performed on September 1, 2016: 64-slice computed tomography plain scan + enhanced scan (arrow). A mass of approximately 84 mm × 61 mm (right and left × back and forth) was observed below the left renal artery and vein, the abdominal aorta, the left psoas major muscle and the front of the left kidney. The edge was smooth, with an uneven density. The plain scan computed tomography value was within 17–41 HU. The arrow indicates the location, shape and size of the mass.

The physician who completed the pathological diagnosis was the chief physician, who had been engaged in pathological diagnosis for 31 years.
