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, and 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 no abnormalities were observed in FDG uptake.
The palatine tonsils showed physiological uptake.
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 uniform density; no abnormalities were observed in FDG uptake.
No enlarged lymph nodes were observed bilaterally in the neck; no abnormalities in FDG metabolism were observed.
A small, solid nodule, approximately 0.2-0.3 cm in length, with clear borders, was observed in the posterior segment of the right upper lobe and the posterior basal segment of the right lower lobe.
FDG metabolism was normal.
A few linear lesions were also observed in both lungs, with normal FDG metabolism.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was not increased.
The liver had an irregular outline.
A low-density lesion was observed in the left medial and left lateral lobes, the larger one approximately 1.4 cm in length, with increased FDG metabolism (SUVmax = 8.5).
Several cystic lesions were also observed within the liver, the largest approximately 0.8 cm in length, with absent FDG uptake.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall and normal local FDG uptake.
A cystic-solid mass measuring approximately 9.5 7.1 cm was observed in the body and tail of the pancreas.
The solid portion showed increased FDG metabolism (SUVmax = 9.2), invading the adjacent gastric wall.
The spleen's morphology, size, density, and FDG uptake were normal.
A punctate dense shadow was observed in the right kidney.
The left kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureter were not widened, and FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Intestinal distension was poor, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
The prostate was of normal size, containing punctate calcifications; FDG uptake was not abnormally increased.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region; FDG metabolism was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
Subcutaneous calcifications were present in both buttocks.
The spinal alignment was normal, with some vertebral body margin osteophytes, L4/5 and L5/S1 intervertebral disc herniation, and bilateral L5 pars interarticularis fracture.
No abnormal FDG metabolism was observed in the entire skeleton.

Impression

1. a. A cystic-solid mass in the body and tail of the pancreas, with elevated FDG metabolism in the solid portion, suggestive of malignancy, most likely pancreatic cancer or cystadenocarcinoma, invading the adjacent stomach wall. b. Liver metastasis.

2. Chronic inflammatory micronodules (solid) in the posterior segment of the right upper lobe and the posterior basal segment of the right lower lobe. A few old lesions in both lungs.

3. Small liver cysts.

4. Small kidney stone in the right kidney. Calcifications in the prostate.

5. Degenerative changes in the spine. Bilateral pars intervertebral disc fracture at L5. L4/5 and L5/S1 intervertebral disc herniation. Subcutaneous calcifications in both buttocks.

6. No abnormalities were found 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.
