questions about my PET SCAN - 1263401

FINDINGS:
Head/Neck: No definite foci of abnormally increased tracer uptake.
are seen in the imaged portion of the head or in the neck. There
is a small mucous retention cyst or polyp in the right maxillary
sinus similar to the prior study. The small density seen in the
left maxillary sinus on the prior study has resolved.

Chest: No definite foci of abnormally increased tracer uptake are
seen in the breasts or axillae. There is a new subcarinal focus of
increased tracer uptake on image 64 with SUVmax 2.7 which
localizes to the esophagus. There is again a large masslike
consolidation in left lung upper lobe now with SUVmax 11.3,
previously 17.4. There is an approximately 1.3 cm nodular opacity
abutting the mediastinal pleura in the medial left lower lobe on
image 79 SUVmax 2.9, previously 1.3 cm with SUVmax 4.1. Just
anterolateral to this on image 86 there is a 1 cm nodule with
SUVmax 2.2, previously less nodular with minimal tracer uptake.
The small left pleural effusion is a little larger than on the
prior study. There is a 4 mm nodule in the posterior medial left
lower lobe on image 72 similar to the prior study. There is mild
scarring at the right apex. There is a 3 mm nodule in the medial
right upper lobe on image 48 similar to the prior study.

Abdomen/Pelvis: There is mildly increased tracer uptake diffusely
in the stomach which may be seen as a normal variant. No definite
foci of abnormally increased tracer uptake are seen in the liver,
spleen, adrenal glands, or pancreas. There is a 1.7 cm mostly fat
density lesion posteriorly in the left kidney on image 119 similar
to the prior study, likely an angiomyolipoma. There is mild
atherosclerotic calcification in the aorta. There is a
nonhypermetabolic 1.9 cm right adnexal cyst on image 192 similar
to the prior study.

Musculoskeletal: There are several new sclerotic bone lesions
including: 1 cm lesion in the right anterior aspect of the L3
vertebral body on image 148 with SUVmax 2.9; 9 mm lesion in the
left aspect of the S1 vertebral body on image 176 with SUVmax 1.6;
1.3 cm lesion in the right supra-acetabular region on image 198
with SUVmax 1.6; and 8 mm lesion in the left femoral neck on image
211 with SUVmax 1.3.

** IMPRESSION **:
There is persistent evidence for a large malignant mass in the
left lung upper lobe, but the intensity of tracer uptake is less
than on the prior study suggesting partial response.

There has been a mixed pattern of changes in the smaller mildly
hypermetabolic nodules in the left lung.

The new focus of mildly increased tracer uptake in the subcarinal
esophagus may be due to inflammation or metastatic disease.

There are several new sclerotic bone lesions with mild tracer
uptake which are most likely metastases, possibly partially
treated given the mild tracer uptake.

The small left pleural effusion is now a little larger than on the
prior study.

Incidental findings including mild aortic atherosclerosis are
noted above.
