SPN was found on my lung during an abdominal scan.
Linear/nodular density at the periphery of the left lung base measuring up to 9 mm in diameter on prior CT 05/2014
Follow up CT 10/2014
The small density at the base of the left lung on the last exam is increased significantly in size and now measures 1.5 cm x 1.3 cm x .09 cm
Follow up PET 10/2014
Ovoid pleural based left lower lobe lung nodule does not demonstrate any FDG uptake. When measured in a similar fashion, the nodule now measures 1.2 X 1.9 cm compared to approximately 0.9 x 1.5 cm on May 2014. Given the location of this nodule just cephalad to the left hemidiaphragm, percutaneous, CT guided percutaneous biopsy would be extremely difficult. No other significant abnormalities.
While the news is great there is no uptake, I've read there can be false negatives with PET scans. My pulmonologist wants another CT scan in 6 months. My concern is the growth rate. Should it keep growing what are the chances of it being benign? Thank you, any insight would be appreciated!
