FULL HISTORY:
68 year old man with esophageal cancer, status post gastric pull-through procedure, June 2002. There was one metastatic lymph node at the time of surgery. He recently had a new, 2 cm right upper lobe mass diagnosed on follow-up CT. This has developed within 6 months since the last chest CT. Evaluate with PET/CT for restaging esophageal cancer.
FOLLOW-UP:
The patient underwent right upper lobectomy. The lesion was a well circumscribed mass measuring 4.0 cm in greatest dimension, with the bulk represented by interstitial fibrosis with foci of bronchial obliteration. The cystic areas contain necroinflammatory debris with no features of malignancy. No fungal organisms are seen. Final diagnosis, pulmonary abscess with acute and chronic inflammation and reactive interstitial fibrosis.
Follow-up chest CT in 7 months (May 2005) was negative for recurrent or metastatic disease.
