EXAM: PET-CT TUMOR IMAGING SKULL TO THIGH

Date of Exam: 09-24-2012

HISTORY: 48-year-old male, Hodgkin's lymphoma diagnosed in left neck. For initial treatment strategy.

TECHNIQUE: RADIOPHARMACEUTICAL: 8.4 mCi F-18 FDG IV.

This is a combined PET/CT scan. PET is performed from base of skull to mid thigh after a 100-minute uptake phase. CT is performed with oral contrast. No IV contrast was given. Blood sugar level is 110 mg% prior to FDG injection.

FINDINGS: Normal blood pool liver demonstrates maximum SUV 2.1. Anterior mid chest wall soft tissue mass left side of midline measuring 4 x 4.7 cm with intense abnormal uptake with maximum SUV 13.5 involving the soft tissue and adjacent mid sternum, which appears to demonstrate mixed lytic and sclerotic characteristics. Metabolically-active nodes seen in right upper and lower paratracheal, prevascular extending up to right-sided precarinal level with intense abnormal uptake. Some of the larger nodes measuring 3.2 x 2 cm precarinal with maximum SUV 8.7, 2.7 x 2 cm right lower paratracheal with maximum SUV 9.6. There is presence of a few bilateral active axillary nodes, right greater than left in number, size and intensity, largest 2.4 x 2 cm right axilla with maximum SUV 4.7. There is  presence of few bilateral supraclavicular level II, III left neck nodes with active uptake, for example measures

1.3 x 1 cm left posterior supraclavicular region with maximum SUV 4.9 (slice 63) subcentimeter level II with mild uptake with maximum SUV 2.4.

No metabolic abnormality in liver, spleen, or adrenal glands. Small area with moderate uptake with maximum SUV 3.2 In portocaval region for which a 2 x 1-cm node is seen on correlating nonenhanced CT (slice 160). Few left mid abdominal retroperitoneal nodes measuring up to 1.5 cm with, mild uptake with maximum SUV up to 2. There are subcentimeter aortocaval and right retroperitoneal nodes on CT but without metabolic abnormality on PET. Uptake in rest of the skeleton is unremarkable.

IMPRESSION:

1. Uptake in multiple nodes above the diaphragm and the left anterior midline chest wall mass involving soft tissue and sternum consistent with active malignancy.

2. Uptake in a few nodes below the diaphragm are only mild to modest in intensity, additional sites of early metastatic disease cannot be completely excluded.
