Hi and welcome to question doctors.com
This could be a benign lung tissue fibroma
f the pulmonary nodule is benign, it usually does not require treatment. If an active infection is found or a disease of inflammation in the body is diagnosed, the treatment would be based on the condition identified and the symptoms that are present.

hi
if its confirmed that its not cancer,then it can be consolidation of lung.A old healed infection or inflammation that may have undergone transformation into fibrous tissue can also show similar findings on a PET scan.
He needs to undergo spirometry to see the functionality of the affected lung.
thanks

Hello there
This can be a benign tumour or partial lung consolidation or collapse.the fact that it is associated with lymph node enlargement is highly suggestive of infective pathology. It may be recent or a old pathology.

HI
IT MAY BE A BENIGN UNHEALED LESION OR A SIMPLE CYST LIKE LESION. SOME INFECTIONS LIKE SARCOIDOSIS IR TUBERCULOSIS CAN MIMIC THE FINDINGS OF TUMOUR.
DETAILED BLOOD INVESTIGATIONS CAN HELP RULE OUT OTHER POSSIBILITIES
