Knowledge integration questions

Last revised by Tom Foster on 27 Jul 2022

Knowledge integration questions are one of the three types of multiple choice questions on Radiopaedia, the other two being basic factual and image interpretation

Knowledge integration questions emphasize the integration of provided information from multiple areas of knowledge. Correctly answering these questions will draw on understanding from a substantial body of knowledge. They should not have an accompanying image. 

These are the most common type of questions used in multiple choice exams but are also the hardest to write. 


A previously well 50-year-old male presents with a mixed solid-cystic posterior fossa mass. Routine lab examinations reveal a significantly elevated hematocrit. The posterior fossa mass most likely represents which of the following? 

  • cerebral metastasis
  • hemangioblastoma [correct answer]
  • pilocytic astrocytoma
  • primary CNS lymphoma
  • pyogenic abscess​
