This 67 year old female had severe COPD. She was found to have lung nodules on her chest CT scan. There was low grade uptake on PET scan. She underwent a needle biopsy that was negative for malignancy, but sustained severe bleeding and this required transfer to SMH . Because of severe lung disease, no open biopsy was done. Approximately 1 year later, she had an open lung biopsy in California and a benign abnormality was discovered.
Please contribute to the differential diagnosis of these abnormalities.
