Nodules Necrotizing Pneumonia

PET Positive  Necrotizing Pneumonia (Nodule)
A small nodule (red arrow a,b,c)was identified on the CT in this 60 year old female who is a smoker .  The SUV at 1.3 was low (usually >2.5 in malignancy. At pathology it was found to be a necrotizing pneumonia. Most necrotizing granulomas are related to infection. Wegener’s granulomatosis Churg-Strauss syndrome, vasculitis, and  sarcoidosis are more often associated with non necrotizing nodules
