Nodules PET Positive

Malignant

Lung Nodule on CXR
In this instance a well defined nodule is noted in the right upper lobe without other obvious adenopathy.  There is a fracture of the right humerus (white ring in c) which may be due to minor trauma in this osteoporotic elderly female though a metastatic lesion to the bone is included as a possibility.  The lungs are hyper inflated characterized by flattened hemi diaphragms and increase in the retrosternal space suggesting emphysema. The lesion was subsequently shown to be carcinoma

Benign

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
