What is the next step in the management of this patient?



Answer

 

  1. The first step in the management of this patient should be investigate if there are any previous studies to compare.  This will allow us to be able to assess if any growth has taken place.  For this patient, there are no previous studies to compare.
  2. The next step would be assess malignancy risk since it is larger than 8mm.  Up to Date uses the Brock University Cancer Equation, which I happen to like as well, though there are several out there and all use clinical, historical, and radiographical criteria.
  3. Our patient has a predicted malignancy risk of 3.54% and using the below algorithm, this patient needs a follow-up CT scan in 3 months to evaluate growth.
