Impression
Increased size of 2.0 x 2.1 cm cystic lesion of the pancreatic head with increased dilatation of the main pancreatic duct up to 7 mm. Focal tracer uptake at the pancreatic head and uncinate process near the junction of the cystic lesion in the main pancreatic duct, which may be related to residual disease. Consider evaluation with contrast-enhanced pancreatic mass protocol CT or MR.
FDG avid lesions in the bony pelvis concerning for osseous involvement of lymphoma.
Hypoattenuating lesions within hepatic segments 2 and 4A are without FDG avidity.
Narrative
COMPARISON: MRI brain 1/10/2025, CT neck chest abdomen pelvis 1/10/2025.
EXAM PURPOSE: Subsequent treatment planning.
ADDITIONAL HISTORY:
Patient with history of Burkitt lymphoma involving the bone marrow, liver, pancreas, left adrenal gland, chest wall, and intracranial dural, complicated by recurrent pancreatitis, status post chemotherapy.
FASTING BLOOD GLUCOSE: 127 mg/dl.
TECHNIQUE:
On 2/10/2025, the patient received intravenous injection of 12.8 mCi 18-fluoro-2-deoxyglucose (FDG) for PET/CT imaging on a GE PET/CT scanner.
Imaging commenced after a 60 minute uptake.
CT TECHNIQUE: Low resolution, noncontrast-enhanced.
Skull vertex to thigh.
Multiplanar PET, CT, and PET/CT fused images were generated using iterative reconstruction and segmented attenuation correction techniques.
FINDINGS:
HEAD/NECK:
There is physiologic distribution of tracer in the pharynx, tonsils, salivary glands, and laryngeal regions.
No abnormal hypermetabolic activity is detected within the neck.
CHEST:
There is normal physiologic myocardial uptake of FDG. No hypermetabolic focus is identified in the chest.
ABDOMEN:
Typical Liver uptake, max SUV 3.1.
There is normal physiologic uptake of FDG in the liver, spleen, kidneys (with excretion into ureters and bladder), and gastrointestinal tract.
Increased size of 2.0 x 2.1 cm cystic lesion of the pancreatic head with increased dilatation of the main pancreatic duct up to 7 mm. Focal tracer uptake at the pancreatic head and uncinate process near the junction of the cystic lesion in the main pancreatic duct, with max SUV 3.9. Atrophy of the pancreatic parenchyma.
PELVIS:
There is physiologic excretion of FDG into the bladder.
SKELETON:
There is mild physiologic uptake of FDG within the bone marrow.
FDG avidity at the right acetabulum with max SUV 4.1, at the left greater than right ischial tuberosities with max SUV 4.7, and at the right inferior pubic ramus and pubic root with max SUV 4.8.
CT: Right chest wall Mediport. 9 mm nodule at the gastrosplenic ligament is without FDG avidity. Hypoattenuating lesions within hepatic segments 2 and 4A are without FDG avidity; the segment 4A lesion is mildly photopenic.
