@bginsy95 just to clarify, does the question require you to pick MRI/MRV or to know that that would be the next step? Primarily a Step 2 card so would be reticent to add a Step 1 tag unless it’s hyper specific to this UW question
19yo female presenting with obesity, comes in with bifrontal headache’s and early morning nausea and vomiting for 4 weeks. appears alert and cooperative. BP, HR are both in within normal range, bmi was obese. fundoscopy was 20/20 bilaterally, neuro exam had no abnormalities, Ct of head revealed nothing.
The answer to the question was a cerebral venous hypertension. It could probably do better for step 2 tagging but the question states that the CT of the head showed no abnormalities. In both idiopathic intracranial hypertension and cerebral venous hypertension, they would show a normal CT of the head. So i was under the assumption that it couldve helped with answering the question because of knowing that you would expect the CT to be normal while the MRI/MRV would be abnormal instead.
It could be better for step 2, but it might have helped with answering the question if a normal CT wouldve ruled in options while also ruling out other options. maybe even in the extra adding “CT would be normal.”
but i apologize if i was under the wrong thought process and tagged improperly!
Ahh I see, all good. MRI is used more to verify that performing an LP is safe and not so much used to diagnose/find evidence of IIH (it can also be grossly normal on MRI!). Don’t think this card would be helpful for the question, but thanks for the suggestion 
Oh ok! Sorry for any inconvenience!!!
