Question of the Day- 6




A 56 year old man is taken to the emergency room after having grand mal seizure during a staff meeting. He has no history of seizure but he complains lately of recurrent headaches on the morning and decrease in intensity later in the day. Laboratory investigations and imaging studies are performed.

Which of these tests will confirm the diagnosis of glioblastoma multiform?

A-Brain biopsy

B-CSF analysis

C-Head CT scan

D-MRI of the brain




Answer:

All tests would suggest the presence of occupying lesion in the brain but the only confirmatory test is the brain biopsy taken during operating on the tumor. It is a common question in the USMLE and it is a tricky one. You should read the question carefully and know the difference between regular primary test and confirmatory test. In this case the next test would be head CT scan but it is not confirmatory and eventually it is not the correct answer.

The correct answer is A

The winner of the day is Shari

Thank you all for your answers and please stick around for the next question of the day.
