Wink Dexamethasone Suppression Test

-Whenever you see a case with positive DST to high dose then pick the option of doing brain CT [because it's most likely cushing disease ie pituitary adenoma]
-Whenver you see a case with negative DST to high dose then pick the option of doing lungs or abdomen CT or U/S because it's most likely ectopic ACTH source such as lung CA or Adrenal adenoma

yah but don't forget that a positive DST could also be a sign of Depression
Major depression specially with psychotic elements can be assessed with a positive DST because they have high cortisol levels that can be suppressed with DST

thanks for the tip anyway
