3. 18FDG-PET scan shows discrepant metabolism between the two masses

The 18FDG-PET scan reveals discrepant metabolism within the two pulmonary masses, showing intense metabolic activity within the left apical mass, but only minimal metabolic activity within the right lower lobe mass. No abnormal tracer activity is seen within peribronchial or mediastinal lymph nodes, and no other sites of significant tracer utilization are present elsewhere inside or outside the thorax.

Given the data available, which of the following represents the most appropriate management step for the evaluation of this patient? (Click on the correct answer to proceed to the seventh of ten pages)

  1. Obtain thoracoscopic surgical lung biopsy of the left apical mass
  2. Obtain transthoracic percutaneous needle biopsy of the left apical mass
  3. Perform 68Ga – PET – CT dotatate scan
  4. Perform bronchoscopy directed at the left apical mass
  5. Serial imaging evaluation of the masses to exclude growth
