Clinical History
The patient is a 78-year-old male with cancer of the throat.
Technique
Forty five minutes following the intravenous injection of 11.7 mCi of 18F-FDG, whole body imaging was obtained from the skull base to the upper thighs. The PET data was also co-registered with the patient's CT Scan of the Neck done one day later.
Findings
1. There is normal physiologic uptake in the brain, heart, genitourinary, and GI tracts.
2. There is an abnormal area of increased uptake in the oropharynx. This measures 13.78 cm sq and was iso-contoured at 2.50. It has a maximum SUV of 4.54 and a mean of 2.99.
3. The co-registered images of the PET and CT scans demonstrate that the entire lesion seen on the CT scan has increased metabolic uptake in the oropharynx.
4. No other abnormal areas of increased focal activity to suggest nodal metastasis.
Impression
ABNORMAL INCREASED ACTIVITY IN THE OROPHARYNX EXTENDING TO THE BASE OF THE TONGUE COMPATIBLE WITH THE PATIENT'S KNOWN SQUAMOUS CELL CARCINOMA. NO OTHER AREAS OF ABNORMAL INCREASED ACTIVITY TO SUGGEST NODAL OR DISTANT METASTASIS.
