Whole-body 18F-FDG PET/CT scan in a patient with Pancreatic Cancer taken from the PETWB-REP dataset. The following English report (translated from original Chinese) is taken verbatim from the public dataset and has not been modified or otherwise checked for accuracy (see the end for citation).

Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, with no significant abnormalities.
The bilateral ethmoid sinus mucosa was slightly thickened, while the mucosa of the remaining paranasal sinuses was not thickened, and the sinus walls were intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal fossa and pterygopalatine fossa structures were normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
The bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear.
Small solid nodules are present in the posterior basal segment of the right lower lobe and the lateral basal segment of the left lower lobe, the largest being approximately 0.3 cm in diameter; FDG uptake is normal.
A few linear lesions are present in both lungs; FDG uptake is normal.
The pleura is slightly thickened bilaterally; there is no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal; the cardiac chamber density is lower than that of the myocardium.
A port-a-cath has been inserted in the right clavicular region.
Punctate dense shadows are seen in the upper inner quadrant of the left breast; no abnormal density shadows are seen in the right breast; FDG metabolism is normal.
The esophagus is not dilated; the esophageal wall is not significantly thickened or lumped; FDG uptake is normal.
The liver's shape and size are normal, with smooth borders and no widening of the hepatic fissure.
CT scan shows no abnormal density shadows within the liver parenchyma, and FDG uptake is normal.
The main portal vein is not significantly widened.
The gallbladder is enlarged, with irregular thickening of the gallbladder wall accompanied by increased FDG uptake (SUVmax = 9.3), with the thickest point approximately 0.9 cm.
Following chemotherapy for pancreatic cancer, catheters are seen in the pancreatic duct and bile duct.
Dilation of the intrahepatic and extrahepatic bile ducts is accompanied by a small amount of gas accumulation.
The pancreatic head is full, with a soft tissue mass showing increased FDG uptake (SUVmax = 7.9), indistinct borders, uneven density, and low-density lesions within.
The mass measures approximately 3.1*3.3*3.1 cm.
No other abnormal density shadows are seen in the pancreas, and FDG metabolism is normal.
The hepatogastric space and retroperitoneal lymph nodes showed an increase in short diameter (approximately 0.8 cm) with elevated FDG uptake (SUVmax = 4.2).
Partial peritoneal density increase with nodules and flocculent shadows was observed, with slightly elevated FDG uptake (SUVmax = 3.2).
Abdominal and pelvic effusion was present.
The spleen was enlarged with uneven density; FDG metabolism was normal.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
The stomach was poorly distended, with thickening of the antral wall and slightly elevated FDG uptake (SUVmax = 2.9).
Intestinal distension was unsatisfactory; the ascending and transverse colon walls were slightly thickened, with continuous elevated FDG metabolism (SUVmax = 10.9).
The uterus is normal in shape and size, with a nodular shadow visible on the anterior wall, approximately 1.5 cm in length.
FDG uptake is normal.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly filled, but no obvious positive stones are seen.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies.
There is an L5/S1 disc herniation with pneumoconiosis and degeneration, and increased density and roughness at the relative margins of the L5/S1 vertebral bodies.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Post-chemotherapy for pancreatic cancer, changes following pancreatic duct and bile duct stent placement, with a mass in the pancreatic head accompanied by increased FDG metabolism, suggesting continued tumor activity. It is recommended to compare previous imaging data and follow up. b. Possible metastasis to the hepatogastric space and retroperitoneal lymph nodes; increased peritoneal density with nodules and flocculent shadows, slightly increased FDG metabolism, suggesting possible peritoneal seeding metastasis; abdominopelvic effusion.

2. Irregular thickening of the gallbladder wall with increased FDG metabolism, suggesting possible gallbladder cancer; cholecystitis to be ruled out. Please combine with enhanced MRI for comprehensive analysis.

3. Chronic inflammatory nodules in the lower lobes of both lungs. A few post-inflammatory remnants in both lungs. Slight thickening of the pleura bilaterally. Anemia changes. Right clavicular port placement.

4. Calcification in the left breast; ultrasound follow-up is recommended.

5. Splenomegaly. Uterine fibroids.

6. Chronic inflammatory changes in the gastric antrum, ascending colon, and transverse colon; endoscopic follow-up is recommended.

7. Degenerative changes in the spine, L5/S1 disc herniation with pneumothorax and degeneration. L5/S1 vertebral endplate inflammation.

8. No obvious abnormalities were found on cranial scintigraphy. A small amount of chronic inflammation in both ethmoid sinuses.

This case is from PETWB-REP, a curated dataset of whole-body 18F-FDG PET/CT scans and corresponding radiology reports from 490 patients with a broad spectrum of malignancies. The data were retrospectively collected from patients who underwent clinically indicated whole-body 18F-FDG PET/CT scans at the Shanghai Universal Medical Imaging Diagnostic Center between 2021 and 2024.
