Spiculated PET positive Cancer with Satellite Nodules The plain film and CT features of this mass in a 66 year female smoker are concerning for the following reasons; size greater than 3cms, shape with spiculated borders and satellite nodules seen in b. The PET scan was positive and biopsy confirmed the diagnosis. Ashley Davidoff TheCommonVein.net 28979c
Elderly Female with a right upper lobe nodule noted on a CXR, confirmed on Chest CT scan. The PET CT confirms hypermetabolic activity in the right upper lobe, but also shows similar activity in an unsuspected ipsilateral mediastinal node. The lesion was subsequently shown to be carcinoma.

PET Positive Adenocarcinoma in a Background of Multicentric Adenocarcinoma with Lepidic Growth The CT is from a 51 year old male who is a smoker who shows a ground glass opacity (GGO) mixed with a solid mass (arrow in a) and multicentric BAC in a lower cut (b) characterised by three areas in the right lower lobe of partial alveolar opacification. Ground glass appearance is the result of partial opacification of the alveoli. Two of the GGOs measure close to 2cms each and the third more anterior measures about 8mms. In this instance a PET scan was positive in the area (green ring in d) It is likely that the solid component in image a represents the transformation of BAC ? (really a carcinoma in situ) into adenocarcinoma. Courtesy Ashley Davidoff MD TheCommonVein.net 87769c02b.8s

Lung Cancer as a Pneumonic Infiltrate There is patchy opacity in the right upper lung which may represent post obstructive atelectasis from the right hilar mass or multifocal airspace disease. Ashley Davidoff MD TheCommonVeiin.net 70M lung ca 001
Lung Cancer as a Pneumonic Infiltrate There is patchy opacity in the right upper lung which may represent post obstructive atelectasis from the right hilar mass or multifocal airspace disease. The minor fissure is elevated and there is a suggestion of SVC encasement Ashley Davidoff MD TheCommonVeiin.net 70M lung ca 006
Lung Cancer as a Pneumonic Infiltrate There is an infiltrate in right upper lung which may represent post obstructive atelectasis from the right hilar mass or multifocal airspace disease. There is narrowing of the right mainstem bronchus and the SVC. These findings are consistent with a primary carcinoma Ashley Davidoff MD TheCommonVeiin.net 70M lung ca 002
Lung Cancer as a Pneumonic Infiltrate There is patchy opacity in the right upper lung which may represent post obstructive atelectasis from the right hilar mass or multifocal airspace disease. There is encasement of the right upper lobe pulmonary artery suggesting a malignant process. Ashley Davidoff MD TheCommonVeiin.net 70M lung ca 005

Lung Cancer as a Pneumonic Infiltrate
There is patchy opacity in the right upper lung. Right upper lobe lung mass is moderately hypermetabolic
with re-demonstration of mediastinal invasion and at least 3 cm of
contact with the chest wall, very concerning for primary lung
malignancy. There is new complete post-obstructive of the right upper lobe which has progressed
Hypermetabolic ipsilateral right supraclavicular, right upper and
lower paratracheal, subcarinal and right middle lobe segmental lymph nodes are most consistent with nodal metastases. No evidence of metastatic adenopathy on the contralateral left side.
