case_images: Case 1. (a) Discrete, enlarged, rounded right adrenal gland (18.7 mm),
  the day before an episode of acute haemorrhage. (b) Preoperative CT
  examination of the abdomen, post-contrast. A strongly enhancing right
  adrenal mass (arrows) is surrounded by a poorly defined
  non-contrast-enhancing area of hypoattenuation (asterisks), extending
  between the renal fossa of the caudate lobe of the liver to the right
  renal vein. There is ventral displacement and compression of the caudal
  vena cava (arrowhead). (c) The excised adrenal gland with an adherent
  peripheral haematoma

case_images: On abdominal ultrasonography the right adrenal gland was enlarged, rounded and discrete (19 mm diameter) (Figure 1). There was a large, localised right retroperitoneal effusion with marked mass effect and no evidence of abdominal or thoracic metastases (Figure 1). At surgery to remove the right adrenal gland (Figure 1), via a ventral midline approach, a haematoma (45 mm diameter) was observed in close proximity to the right adrenal gland, just ventral to the caudal vena cava.

case_images: Case 2. (a,b) Right adrenal tumour adherent to, but not invading, the
  caudal vena cava. (c) The excised adrenal tumour containing (d)
  extensive areas of intratumoral necrosis and haemorrhage

case_images: The adrenal mass contained a large amount of intratumoral haemorrhage and necrosis on cut section (Figure 2).
