never visited LUNG NODULE, DIAGNOSIS
Contributed by: Nuclear Medicine, Radiologist, Stanford University, California, USA.
Patient: 77 year old male
History:

77-year-old man with a CT scan evaluating renal
cysts, demonstrated some soft tissue densities in bilateral lung
bases. A PET scan is requested to evaluate the lung nodules

This case has no images yet.
Findings:

BRAIN: Physiologic activity is noted in the imaged portions of the
brain.

HEAD AND NECK: Physiologic activity is noted in the extraocular
muscles, adenoids, parotid glands, bilateral longus colli muscles.
No abnormal foci within the cervical, supraclavicular axillary
regions.

CHEST: The lungs appear clear. No metabolic activity is normal
and the bilateral lung base nodules ranging from 5 mm - 1.5 cm on
the CT scan. Nodules less than 7 mm may be too small to adequately
characterize with PET. Physiologic cardiac activity is noted.
Physiologic FDG uptake is also noted in the intercostal muscles.
FDG uptake is noted in the wall of the right ventricle, suggestive
of right ventricular hypertrophy, further attention to this region
is recommended.

ABDOMEN AND PELVIS: Physiologic activity of the liver, spleen,
stomach, bowel with physiologic clearance in the kidneys, right
ureter, and bladder.

SKELETON: Physiologic activity is noted throughout the skeletal
axis.

Diagnosis:


1. METABOLICALLY INACTIVE LUNG NODULES ARE LIKELY BENIGN. HOWEVER
A LUNG NODULE LESS THAN 7 MM MAY BE TOO SMALL TO ADEQUATELY
CHARACTERIZE WITH PET.

2. FDG UPTAKE IN THE RIGHT VENTRICULAR WALL MAY BE SUGGESTIVE OF
RIGHT VENTRICULAR HYPERTROPHY, FURTHER ATTENTION TO THIS REGION IS
RECOMMENDED
