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: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
Both eyes were symmetrical with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology and structure.
The right lobe of the thyroid gland is enlarged, with several low-density nodules, the largest approximately 1.0 cm in diameter.
FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear bilaterally.
Several solid nodules are observed in the upper lobes of both lungs, the largest approximately 0.4 cm in diameter.
FDG uptake is normal.
Scattered linear lesions are present in both lungs, with normal FDG uptake.
Bilateral pleural thickening with a small amount of pleural effusion is present.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal.
Calcification of some arterial walls (including coronary arteries) is present.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or lumped.
FDG uptake is not increased.
The liver's shape and size are normal, with smooth borders and no widening of the hepatic fissure.
Several small cystic lesions are present within the liver, the largest being approximately 0.7 cm in diameter.
FDG uptake is normal.
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder's shape and size are normal, but its internal density is increased.
Nodular thickening is present at the gallbladder fundus, with no abnormal local FDG uptake.
The pancreatic tail is thickened with a cystic-solid mass with indistinct borders, measuring approximately 8.9*4.6 cm.
The solid portion shows unevenly increased FDG uptake (SUVmax = 6.5).
The boundary between the mass and adjacent spleen and the transverse colonic splenic flexure is indistinct, and the surrounding fat spaces are poorly visualized.
Multiple indistinct exudative shadows are visible.
Patchy low-density lesions are seen within the spleen, with absent FDG uptake.
Multiple enlarged lymph nodes were observed in the left mesenteric region of the abdominal cavity, the largest measuring approximately 3.3*3.7cm.
FDG uptake was increased, with an SUVmax of 10.2.
A small amount of fluid was present in the abdominopelvic cavity.
No dilation of the pancreatic duct was observed, and no abnormal density shadows were seen in the remaining pancreas.
FDG metabolism was normal.
A few exudative shadows were observed around both kidneys, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal gland contrast was normal.
The stomach was poorly distended, with slight thickening of the walls of the cardia, part of the gastric body, and antrum.
FDG uptake was increased, with an SUVmax of 3.0.
Contrast agent residue was observed in the intestinal lumen.
The appendix was thickened with cystic dilatation, and the intestinal wall was thickened with increased FDG uptake, with an SUVmax of 9.0.
The prostate was full, with punctate dense shadows inside.
FDG uptake was not abnormally increased.
The bladder is adequately full, but the density within the bladder is increased.
The spinal alignment is normal, with some vertebral body margin osteophytes, L4/5 and L5/S1 intervertebral disc bulging, and L5/S1 intervertebral disc pneumoconiosis and degeneration.
Systemic bone marrow FDG metabolism is normal.

Impression

1. A mass in the pancreatic tail with elevated FDG metabolism suggests pancreatic cancer invading the adjacent spleen and splenic flexure of the transverse colon. Please correlate with clinicopathology. Multiple lymph node metastases in the left mesenteric cavity and a small amount of effusion in the abdominopelvic cavity are also present.

2. Thickened appendix with cystic dilatation and thickened intestinal wall with elevated FDG metabolism suggest possible cystadenoma, but cystadenoma should be ruled out. Please correlate with clinical findings and colonoscopy.

3. Chronic inflammatory micronodules in the upper lobes of both lungs. Scattered post-inflammatory lesions in both lungs. Bilateral pleural thickening with a small amount of pleural effusion. Calcification of some arterial walls (including coronary arteries).

4. Liver cyst. Splenic infarction. Possible gallbladder adenomyosis; residual contrast agent in the gallbladder and bladder. Benign prostatic hyperplasia with calcification.

5. Chronic inflammatory changes in part of the gastric wall; please follow up with gastroscopy.

6. Degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulge, L5/S1 disc pneumoconiosis and degeneration.

7. Low-density nodule in the right lobe of the thyroid gland, FDG metabolism normal, suggestive of nodular goiter, please confirm with ultrasound examination.

8. Age-related brain, deep lacunar infarcts, please confirm with MRI examination.

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.
