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: a linear low-density shadow in the left basal ganglia with absent FDG uptake; a few punctate low-density shadows in the deep bilateral brain regions with no significant abnormalities in FDG uptake; widening of the ventricles, sulci, fissures, and cisterns, with symmetrical bilateral ventricles and no midline shift; symmetrical bilateral eyeballs with no significant abnormalities; no thickening of the paranasal sinus mucosa and intact sinus walls; no thickening of the nasopharyngeal wall with no abnormal FDG uptake; symmetrical bilateral pharyngeal recesses with no stenosis of the Eustachian tube openings; normal structures of the infratemporal and pterygopalatine fossae; clear bilateral parapharyngeal spaces with no abnormal FDG uptake; physiological uptake of both palatine tonsils; normal morphology and structure of the laryngopharynx; no abnormal density shadows in the bilateral parotid and submandibular glands; and no abnormal FDG uptake in the thyroid gland.
Enlarged lymph nodes were observed in the left supraclavicular fossa and left posterior cervical triangle, the largest measuring approximately 1.5 cm in short diameter, with increased FDG metabolism (SUVmax = 5.9).
Diffuse solid nodules of varying sizes were observed in both lungs, most of which were fused together, the largest measuring approximately 1.5 cm in long diameter, with increased FDG metabolism (SUVmax = 3.6).
Small amounts of pleural effusion were present bilaterally.
No significantly enlarged lymph nodes were observed 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.
Both breasts appeared normal, with no abnormal FDG metabolism.
The liver showed no significant abnormalities in shape or size, with smooth borders, no widening of the hepatic fissure, and no abnormal density shadows in the liver parenchyma on plain CT scan, with no abnormal FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, with slight wall thickening and no abnormal local FDG uptake.
The pancreas showed fullness and bulging in the neck and body with mass formation, increased FDG metabolism (SUVmax = 5.3), and a size of approximately 3.0*3.2cm.
The pancreatic duct was dilated, and the pancreatic tail was atrophied.
The peritoneum in the abdominopelvic cavity was diffusely thickened, presenting as multiple nodular or flocculent areas, with increased FDG metabolism (SUVmax = 8.6).
The spleen showed no abnormalities in morphology, size, density, or FDG uptake.
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 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 no significant abnormalities in FDG uptake.
The intestines were poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake was physiological.
The uterus was normal in shape, with no abnormal density shadows and no abnormal FDG metabolism.
No abnormal FDG metabolism was observed in the bilateral adnexa.
The bladder was generally full, with no obvious positive stones.
Multiple enlarged lymph nodes were observed around the pancreas, at the porta hepatis, and beside the abdominal aorta, the largest with a short diameter of approximately 1.0 cm.
FDG metabolism was elevated, with an SUVmax of 3.5.
There was fluid accumulation in the abdominopelvic cavity.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulging.
FDG uptake was not abnormal.
This was following a left total humeral head replacement surgery, after which FDG metabolism was normal.

Impression

1. a. A mass in the neck and body of the pancreas, with elevated FDG metabolism, suggestive of pancreatic cancer. Extensive peritoneal metastasis in the abdominopelvic cavity. b. Metastasis to the peripancreatic, hepatic hilum, retroperitoneum, left supraclavicular fossa, and left posterior cervical triangle lymph nodes. c. Diffuse metastases in both lungs. Abdominal and pelvic effusions. Small amounts of pleural effusion bilaterally.

2. Chronic cholecystitis.

3. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges. Post-left total hip replacement surgery changes.

4. Left basal ganglia softening lesion, a few ischemic lesions in the deep bilateral brain regions, senile encephalopathy.

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.
