Whole-body 18F-FDG PET/CT scan in a patient with Liver 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, and resting, a whole-body PET/CT scan was performed.
The whole-body tomographic images showed:The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the bilateral ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal; the bilateral pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal fossa and pterygopalatine fossa structures were normal, and the bilateral parapharyngeal spaces were clear, with no abnormalities in FDG uptake.
No abnormalities in FDG uptake were observed in the oropharynx and laryngopharynx.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density, and no abnormalities in FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
FDG metabolism was normal.
Lung markings were clear bilaterally, with no obvious abnormal density shadows.
FDG uptake was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The density of the cardiac chambers was slightly lower than that of the myocardium.
The liver was enlarged with irregular edges, containing a large, mixed-density mass that appeared fused together with indistinct borders and uneven internal density, occupying the right lobe and left medial lobe of the liver.
Uneven FDG uptake was increased, measuring approximately 13.0 8.1 11.6 cm, with an SUVmax of 8.6.
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 no abnormal local FDG uptake.
The pancreas is poorly visualized.
The spleen shows no abnormalities in morphology, size, density, or FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal glands show no obvious abnormalities on contrast.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or swollen.
FDG uptake is not increased.
The stomach is poorly filled, and the stomach wall is not significantly thickened.
FDG uptake is not significantly abnormal.
The intestines are poorly filled, with increased FDG metabolism in the ileocecal region (SUVmax = 5.6).
The bladder is generally full, and no obvious positive stones are seen.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region.
FDG metabolism is not abnormal.
No significant fluid accumulation is seen in the abdomen or pelvic cavity.
The spinal alignment is normal, with no abnormal density shadows observed in the vertebral bodies.
FDG uptake is normal.
Systemic bone marrow FDG metabolism is normal.

Impression

1. A large mass in the liver with unevenly increased FDG uptake suggests a malignant tumor, possibly hepatoblastoma. Please correlate with clinicopathology.

2. Signs of anemia.

3. Inflammatory or physiological uptake in the ileocecal region.

4. No abnormal density shadows or abnormally increased FDG uptake observed in the bones throughout the body.

5. No obvious abnormalities were found on cranial imaging.

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.
