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, with punctate low-density shadows in the deep cerebral regions bilaterally; FDG uptake was not significantly abnormal.
Some ventricles, sulci, fissures, and cisterns showed widening, but local density and FDG uptake were normal; midline shift was not observed.
The bilateral eyeballs showed normal morphology and outline; retrobulbar structures were clear; optic nerves were symmetrical bilaterally; FDG uptake was not significantly abnormal.
No thickening of the paranasal sinus mucosa was observed; sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; FDG uptake was normal; bilateral pharyngeal recesses were symmetrical; Eustachian tube openings were not narrowed; the infratemporal and pterygopalatine fossae were structurally normal; bilateral parapharyngeal spaces were clear; FDG uptake was normal.
Bilateral palatine tonsils were full and showed physiological FDG uptake.
The laryngopharynx showed no abnormalities in morphology and structure.
Bilateral salivary glands showed no abnormal visualization.
The thyroid gland was normal in morphology and size, with uniform density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake was normal.
The thorax was symmetrical bilaterally; bronchiectasis was observed in both lungs, with scattered nodules, patchy shadows, and linear shadows; some showed slight FDG uptake.
Multiple lymph nodes were observed in the bilateral hilar and mediastinal regions, the largest with a short diameter of approximately 0.7 cm; FDG uptake was increased, SUVmax = 4.8.
Mild pleural thickening was observed bilaterally; a small amount of pleural effusion was observed in the left pleural cavity.
The cardiac silhouette was normal.
Following coronary artery stenting, some arterial walls showed calcification (including the coronary arteries).
The esophagus was not dilated; the esophageal wall was not significantly thickened or showed masses; FDG uptake was normal.
The liver was irregularly shaped, with irregular borders and slightly widened hepatic fissures.
No significant abnormal density shadows were observed in the liver parenchyma; FDG uptake was normal.
The main portal vein was not significantly widened; no dilation of intrahepatic or extrahepatic bile ducts was observed.
This was following cholecystectomy.
A mixed low-density mass was observed in the tail of the pancreas, with indistinct borders and uneven density, measuring approximately 4.6*3.6cm.
FDG uptake was increased, with an SUVmax of 15.3.
No significant dilation of the main pancreatic duct was observed.
The spleen was enlarged, containing a low-density mass with relatively clear borders; the largest measured approximately 4.5*5.6cm, with increased FDG uptake and an SUVmax of 11.7.
Multiple lymph nodes were observed in the retroperitoneum, mesentery, left iliac vessels, bilateral diaphragmatic crura, left subpleural region, and left internal mammary chain; the largest had a short diameter of approximately 3.4cm, with increased FDG uptake and an SUVmax of 21.9.
Thickening of the left upper peritoneum and adjacent diaphragm was observed, with increased FDG uptake (SUVmax of 12.8), and indistinct demarcation from the adjacent gastric fundus.
A small amount of effusion was observed in the pelvic cavity.
The kidneys were normal in shape and size, but multiple cystic lesions were observed in both kidneys, the largest having a long diameter of approximately 5.1cm.
No widening of the renal pelvis, calyces, or ureters was observed bilaterally, but high-density contrast agent residue was seen within them.
The bilateral adrenal glands showed no abnormalities in morphology or density, and FDG uptake was normal.
Bowel preparation was poor; no obvious masses were seen in the intestinal wall, but continuous FDG uptake was observed in some intestinal segments (SUVmax = 12.8).
The prostate showed no abnormalities in morphology or size, with a transverse diameter of approximately 3.7 cm; calcifications were observed in the parenchyma, and FDG uptake was not significantly increased.
Bladder distension was poor, and high-density contrast agent residue was seen within it.
The L5 vertebral body was sulcatrate, with osteophyte formation at the vertebral margins.
L2/3, L3/4, and L4/5 intervertebral disc bulges were observed, along with pneumothorax at L4/5 and L5/S1.
Nuchal ligament calcification was present.
The right humeral head showed expansile bone destruction with marginal sclerosis; FDG uptake was not significantly abnormal.

Impression

1. A mass in the tail of the pancreas with increased FDG metabolism; a mass in the spleen with increased FDG metabolism; thickening of the left upper quadrant peritoneum and adjacent diaphragm with increased FDG metabolism; multiple enlarged lymph nodes throughout the body with increased FDG metabolism. These findings suggest malignancy, possibly pancreatic cancer with multiple metastases, or multi-systemic lymphoma. A comprehensive analysis combining tumor markers is recommended, and a biopsy may be necessary.

2. Bronchiectasis in both lungs with chronic inflammation and remnants. Reactive hyperplasia of the hilar and mediastinal lymph nodes in both lungs. Mild pleural thickening bilaterally, with left-sided pleural effusion. Post-coronary stent placement, with partial arteriosclerosis (including coronary arteries).

3. Liver cirrhosis. Multiple renal cysts. Residual contrast agent in the urinary system. Prostatic calcifications.

4. Continuous increased FDG metabolism in parts of the intestine, considered to be physiological uptake or chronic inflammation.

5. Spinal degeneration. L5 vertebral instability. L2/3, L3/4, L4/5 intervertebral disc bulge; L4/5, L5/S1 intervertebral disc pneumoconiosis and degeneration. Benign osteopathy of the right humeral head.

6. Bilateral deep lacunar infarcts, age-related brain 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.
