Questions and Answers

What is the purpose of transillumination during a physical exam?

  • To identify fluid-filled lesions (correct)
  • To differentiate between benign and malignant lesions
  • To detect calcific or radio-opaque densities within the mass
  • To establish connections with bones and joints

Which feature is NOT typically associated with malignant lesions?

  • Greater than 5cm diameter
  • Mobile (correct)
  • Less than 3cm diameter
  • Deep

What imaging modality is particularly useful for differentiating some tumors from infections?

  • Magnetic Resonance Imaging (MRI)
  • Computed Tomography (CT) (correct)
  • Positron Emission Tomography
  • Ultrasonography
