Default Tricky question in USMLE 2015

A 67 year old man visits his primary care physician for evaluation. Yesterday he had a seizure for the first time in his life. His co-workers told him that he lost consciousness all of sudden and started shaking his hands and legs for about two minutes. They called the ambulance but he was completely normal when paramedics arrived. He refused to go to the ER and told them that he will visit his regular doctor next day. His doctor orders some tests to exclude a brain tumor.
What is the most accurate test to confirm a diagnosis of brain tumor?
A- MRI of the brain
B- CT scan of the head
C- Hormonal assay
D- Brain biopsy

Initial test=MRI brain. MOST ACCURATE=Brain biopsy, nearly 100% sensibility and specificity, but too invasive

Thankfully, the USMLE is moving away from trick questions like this.

There are few neoplasms for which imaging is the definitive, confirmatory test. In 99% of cases, you will need tissue to confirm a diagnosis.

The answer is brain biopsy, but realize this is simply because of the tricky wording.

If the question had simply asked for which test you would order or for the most sensitive test, then MRI would be the answer.

Agreed, I avoid that blog completely.
