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, a whole-body PET/CT scan was performed.
The whole-body scan showed: Normal brain morphology and structure, with punctate, slightly low-density shadows in the deep brain regions; no abnormalities were observed in FDG metabolism.
Mild widening of the ventricles, sulci, fissures, and cisterns was observed; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
Thickening of the mucosa was observed in the bilateral ethmoid sinuses and the left maxillary sinus; no thickening was observed in the mucosa of the remaining paranasal sinuses, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; FDG uptake was normal; the pharyngeal recesses were symmetrical bilaterally; there was no stenosis of the Eustachian tube openings; the infratemporal fossa and pterygopalatine fossa structures were normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
The palatine tonsils showed physiological uptake bilaterally.
A soft tissue nodule, approximately 1.1 cm in diameter, was observed in the right parotid region; FDG uptake was increased, with SUVmax = 8.7.
No abnormal density shadows were seen in the left parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland was normal in shape and size, with slightly uneven density; FDG uptake was normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Increased lung markings were observed in both lungs, with multiple solid nodules, the largest approximately 0.3 cm in diameter.
FDG uptake was normal.
Increased FDG uptake was observed in the lower lingular segment of the left upper lobe and in patchy and linear lesions in both lower lobes (SUVmax = 2.9), most notably in the right lower lobe.
Right pleural thickening and a small amount of pleural effusion were present in the right pleural cavity.
Lymph nodes were visualized in the right hilum, pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region; the largest had a short diameter of approximately 1.0 cm and increased FDG uptake (SUVmax = 2.7).
The cardiac silhouette was normal; the cardiac chamber density was lower than that of the myocardium.
Calcification of some arterial walls (including coronary arteries).
No esophageal dilation, significant wall thickening or mass, and no increased FDG uptake were observed.
The liver margins were not smooth; a large, irregular mass was observed in the right lobe, with indistinct borders, a maximum cross-sectional size of approximately 15.6*10.2cm, and heterogeneous density with unevenly increased FDG uptake (SUVmax = 8.8).
The remaining liver tissue showed uneven density, but no abnormalities in FDG metabolism.
Increased FDG metabolism was observed in the right branch of the portal vein (SUVmax = 8.8).
Hilar and retroperitoneal lymph nodes were visualized, the largest with a short diameter of approximately 0.8cm; no abnormalities in FDG uptake were observed.
Abdominal and pelvic effusion were present.
The gallbladder was normal in shape and size, with slight thickening of the gallbladder wall and no abnormalities in localized FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen is normal in shape, size, density, and 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 gland imaging is normal.
The stomach is poorly filled, with slight thickening of the cardia, part of the gastric body, and antrum walls.
FDG uptake is slightly increased, with SUVmax = 3.4.
The intestines are poorly filled, with continuous FDG uptake in parts of the intestine, SUVmax = 20.5.
The prostate is enlarged, with a long diameter of approximately 4.8 cm, and calcifications are seen within it.
FDG uptake is not abnormally increased.
Bilateral vas deferens calcification is present.
The bladder was poorly filled, but no obvious stones were observed.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 disc bulges.
Subcutaneous calcification was present in the right buttock.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. A mass in the right lobe of the liver with elevated FDG metabolism, suggestive of malignancy, most likely primary liver cancer. Please combine clinical findings with enhanced MRI for comprehensive analysis. b. Liver cirrhosis. Reactive hyperplasia of the hilar and retroperitoneal lymph nodes. Abdominal and pelvic effusion. c. Possible right portal vein tumor thrombus formation.

2. a. Chronic inflammatory micronodules in both lungs. Chronic inflammation in both lungs (more pronounced in the lower right lobe) and post-inflammatory remnants. b. Right pleural thickening, small amount of right pleural effusion. Reactive hyperplasia of the right hilar and mediastinal lymph nodes. Anemia changes, calcification of some arterial walls (including coronary arteries).

3. Chronic cholecystitis. Benign prostatic hyperplasia with calcification. Bilateral vas deferens calcification.

4. Chronic inflammatory changes in part of the stomach wall and intestines; please follow up with endoscopy.

5. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge. Subcutaneous calcification in the right buttock.

6. Soft tissue nodule in the right parotid gland with increased FDG metabolism, suggestive of lymphoma; please follow up with MRI.

7. Deep lacunar infarcts in the brain, mild age-related brain changes. Minor chronic inflammation in both ethmoid sinuses and the left maxillary sinus.

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.
