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: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no significant abnormalities.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; no abnormalities were observed in FDG uptake; the pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally; and FDG uptake was normal.
The palatine tonsils showed physiological uptake bilaterally.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in morphology and size, with slightly uneven density; FDG uptake was normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Scattered solid nodules were observed in both lungs, the largest being approximately 1.4*1.0cm in the posterior segment of the right upper lobe, with normal FDG uptake in both nodules.
No pleural thickening or pleural effusion/pneumothorax was observed bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette appeared normal.
The esophagus showed no dilation, wall thickening, or mass, and FDG uptake was not increased.
The liver was relatively small with smooth borders; the hepatic fissure was not widened.
A slightly low-density lesion measuring approximately 2.0*0.9cm was seen in the right posterior lobe of the liver on plain CT scan, with normal FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was not full, but showed increased density within the gallbladder, with normal local FDG uptake.
An irregular low-density lesion measuring approximately 3.9*2.2cm was seen in the body and tail of the pancreas, with increased FDG metabolism and an SUVmax of 6.9.
Multiple diffuse nodules and thickened soft tissue shadows were observed in the peritoneum, subcapsular region of the liver, greater omentum, and mesentery of the abdominopelvic cavity.
The largest nodule, measuring approximately 5.7 x 2.1 cm, was located around the pancreatic tail.
FDG metabolism was increased, with an SUVmax of 6.4.
A large amount of fluid was present in the abdominopelvic cavity.
The spleen showed no abnormalities in morphology, size, density, or FDG uptake.
Both kidneys were normal in morphology and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was not significantly abnormal.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
The stomach was poorly distended, with no obvious thickening of the gastric wall, and FDG uptake was not significantly abnormal.
The intestines were poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake was physiological.
FDG metabolism in the anal canal was increased, with an SUVmax of 4.7.
The prostate was enlarged, with a transverse diameter of approximately 5.1 cm, and punctate calcifications were observed internally.
FDG uptake was not abnormally increased.
The bladder was generally distended, and no obvious positive stones were observed.
Bilateral hydrocele with calcifications.
Spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulges.
No abnormal FDG metabolism was observed in the entire skeleton.

Impression

  1. A mass in the body and tail of the pancreas (mainly the tail), with elevated FDG metabolism, strongly suggestive of pancreatic cancer; please correlate with clinical findings. Extensive metastasis to the peritoneum, subcapsular region of the liver, greater omentum, and mesentery. Significant effusion in the abdominal and pelvic cavities.

  2. Scattered solid nodules in both lungs, with no elevated FDG metabolism, strongly suggestive of chronic inflammatory nodules; please correlate with CT follow-up.

  3. Small liver size, with a slightly low-density lesion in the right posterior lobe, with no elevated FDG metabolism; hemangioma is a possibility; please correlate with contrast-enhanced examination.

  4. Chronic cholecystitis with gallstones.

  5. Benign prostatic hyperplasia with calcification. Bilateral hydrocele with calcification. Hemorrhoids.

  6. Partial vertebral osteophyte formation. L4/5 and L5/S1 intervertebral disc bulge.

  7. No obvious abnormalities on cranial scintigraphy.

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.
