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 scan revealed multiple irregular, mixed-density masses and nodules in the right occipital, parietal, and left temporal lobes.
The largest mass, approximately 4.8 3.2 cm, was located in the right occipital lobe.
Some masses showed increased FDG metabolism (SUVmax = 8.3), with mild surrounding edema.
No widening of the ventricles, sulci, fissures, or cisterns was observed.
The ventricles were symmetrical, and there was no midline shift.
Both eyes were symmetrical and showed no obvious 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 pharyngeal recesses were symmetrical, and there was no stenosis of the Eustachian tube openings.
The infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear with no abnormal 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 is normal in shape and size, with uniform density, and FDG uptake is normal.
No enlarged lymph nodes are seen bilaterally in the neck, and FDG metabolism is normal.
Diffuse nodules of varying sizes are present in both lungs, the largest being approximately 2.7 2.5 cm in the lower lobe of the left lung, with increased FDG metabolism (SUVmax = 4.5).
Scattered linear shadows are seen in both lungs, more prominent in the upper lobe of the right lung, with normal FDG uptake.
Slight pleural thickening is present bilaterally.
Multiple enlarged lymph nodes are seen in the bilateral hilum, pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region, the largest being approximately 1.2 cm in short diameter, with increased FDG metabolism (SUVmax = 7.5).
The cardiac silhouette is normal, with slight pericardial thickening.
Some arterial walls show calcification.
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is normal.
The liver has an irregular outline, disproportionate lobes, and widened fissures.
An irregular mass measuring approximately 9.1 8.5 5.5 cm is seen in the lower segment of the right anterior lobe, with increased FDG metabolism (SUVmax = 8.8).
No dilation of intrahepatic or extrahepatic bile ducts is observed.
Intestinal loops are visible at the anterior border of the liver.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
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, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormal FDG uptake.
Bilateral adrenal glands show no obvious abnormalities on contrast.
The stomach is poorly distended, with no obvious thickening of the gastric wall and no obvious abnormal FDG uptake.
Post-procedure for intestinal polyps, metallic sutures are seen in the rectum, with no abnormal FDG metabolism.
Increased FDG metabolism in part of the colon, SUVmax = 5.6.
The prostate is of normal size and uniform density, with no abnormally increased FDG uptake.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region, and FDG metabolism was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulging, but FDG uptake was normal.
Calcification of the nuchal ligament was present.
No abnormal FDG metabolism was observed throughout the skeleton.

Impression

1. a. Mass lesion in the lower segment of the right anterior lobe of the liver, with increased FDG metabolism, suggestive of hepatocellular carcinoma. b. Diffuse metastases in both lungs. Multiple intracranial metastases. c. Cirrhosis.

2. Scattered chronic inflammation and old lesions in both lungs (most prominent in the upper lobe of the right lung). Slight thickening of the pleura bilaterally. Enlarged chronic inflammatory lymph nodes in the hilar and mediastinal regions. Calcification of some arterial walls. Slight pericardial thickening.

3. Postoperative changes after intestinal polyp surgery. Intervertebral colon. Increased FDG metabolism in part of the colon, suggestive of physiological or inflammatory uptake.

4. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

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.
