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 with both hands raised, extending from the top of the skull to the upper thigh.
The 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.
Both eyeballs were symmetrical and showed no significant abnormalities.
No thickening was observed in the paranasal sinus mucosa; 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.
No abnormalities were observed in FDG uptake 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 were observed in FDG uptake.
Multiple solid nodules were observed in both lungs with relatively clear borders.
The largest nodule measured approximately 0.3 cm in length.
Scattered linear shadows were also seen in both lungs.
No abnormal FDG uptake was observed.
There was no pleural thickening or pleural effusion/pneumothorax.
Multiple lymph nodes were observed in the mediastinum (right paratracheal, pretracheal, and post-vena cava) and bilateral supraclavicular fossae.
The largest lymph node measured approximately 0.9 cm in short diameter.
Some of these lymph nodes showed increased FDG uptake, with an SUVmax of 2.2.
The cardiac silhouette was enlarged, with slight pericardial thickening and a cardiac chamber density slightly lower than myocardial density.
Both breasts were relatively dense, and FDG uptake was normal.
The liver margins were irregular, and the hepatic fissure was widened.
A large soft tissue mass was observed in the right lobe of the liver, with indistinct borders and heterogeneous internal density, measuring approximately 11.9 cm 11.0 cm 13.8 cm.
FDG uptake was increased, with an SUVmax of 11.3.
Part of the right branch of the portal vein was involved.
Multiple enlarged lymph nodes were observed in the porta hepatis and upper abdominal retroperitoneum, the largest measuring approximately 3.4 cm in short diameter, with increased FDG uptake (SUVmax = 9.5).
Multiple smaller lymph nodes were also observed in the retroperitoneum and bilateral iliac vessels, the largest measuring approximately 0.6 cm in short diameter, with normal FDG uptake.
The peritoneum in the abdominopelvic region showed flocculent increased density.
Multiple nodular shadows were observed in the right upper quadrant and right paracolic gutter peritoneum, the largest measuring approximately 1.7 cm 0.9 cm, with increased FDG uptake (SUVmax = 9.2).
Fluid-density shadows were observed in the pelvic cavity.
The gallbladder was of normal morphology, with slightly increased density within the lumen; FDG uptake was normal.
The pancreas was normal in morphology, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
The spleen was of normal morphology, containing a low-density nodule with a relatively clear border, approximately 0.5 cm in long diameter; FDG uptake was normal.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
The right adrenal gland shows no obvious abnormalities on contrast.
The left adrenal gland is slightly thickened, with increased FDG uptake (SUVmax = 2.5).
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is not increased.
The stomach is poorly filled, with no obvious thickening of the stomach wall; FDG uptake is not significantly abnormal.
The intestines are poorly filled, with no obvious thickening or swollen intestinal wall; FDG uptake is physiological.
Focal increased FDG uptake is observed in the anal region (SUVmax = 4.2).
The uterus is normal in shape, with no abnormal density shadows and no abnormally increased FDG uptake.
No abnormal FDG uptake is seen in the bilateral adnexa.
The bladder is generally full, with no obvious positive stones.
The spinal alignment is normal.
Calcification is visible in the nuchal ligament, with osteophyte formation at the margins of some vertebral bodies.
The L4/5 intervertebral space is narrowed, and an L4/5 disc herniation with pneumothorax is present.
Low-density nodules with sclerosis are seen on the anterolateral aspect of both femoral heads; no abnormal uptake is observed on FDG.
The right 5th rib shows a slightly abnormal morphology; no abnormal uptake is observed on FDG.

Impression

1. a. A large mass in the right lobe of the liver, with elevated FDG metabolism, suggestive of hepatocellular carcinoma, involving the right branch of the portal vein; clinical correlation is required. b. Metastasis to the hepatic hilum and upper abdominal retroperitoneal lymph nodes; multiple lymph node metastases beside the bilateral iliac vessels need to be ruled out. Peritoneal seeding metastasis, pelvic effusion. c. Reactive hyperplasia of the mediastinal and bilateral supraclavicular fossa lymph nodes, with partial metastasis need to be ruled out.

2. Multiple chronic inflammatory micronodules in both lungs are highly probable; scattered post-inflammatory lesions in both lungs; follow-up CT scan is required. Cardiac enlargement, slightly thickened pericardium, mild anemia.

3. Cholestasis in the gallbladder. Small vascular tumor in the spleen. Left adrenal hyperplasia.

4. Hemorrhoidal manifestations; specialist examination recommended.

5. Spinal degenerative changes. L4/5 vertebral endplate inflammation, L4/5 intervertebral disc herniation with pneumatosis and degeneration. Bilateral femoral head herniation fossa. Possible post-traumatic changes in the right 5th rib; clinical correlation is required.

6. No obvious abnormalities were found on brain 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.
