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 a few patchy low-density shadows in the deep brain regions; increased FDG metabolism in the left temporal lobe (SUVmax = 8.4).
Widening of the ventricles, sulci, fissures, and cisterns; symmetrical bilateral ventricles; no midline shift.
Symmetrical bilateral eyeballs with no obvious abnormalities.
Thickened mucosa bilaterally of the maxillary sinuses, with intact sinus walls.
No thickening of the nasopharyngeal wall; no abnormal FDG uptake; symmetrical bilateral pharyngeal recesses; no stenosis of the Eustachian tube openings; normal structures of the infratemporal and pterygopalatine fossae; clear bilateral parapharyngeal spaces with no abnormal FDG uptake.
Pharyngeal tonsils showed physiological uptake.
No abnormalities in the morphology and structure of the laryngopharynx.
No abnormal density shadows in the bilateral parotid and submandibular glands.
Normal thyroid morphology and size, with slightly uneven density; no abnormal FDG uptake.
Several lymph nodes were observed in the bilateral deep cervical spaces and submandibular region, the largest being approximately 0.8 cm in short diameter, with mildly increased FDG metabolism (SUVmax = 2.7).
Multiple roundish solid nodules were observed in both lungs, with clear borders; the largest, located in the posterior basal segment of the left lower lobe, was approximately 1.6 cm in diameter, with increased FDG metabolism (SUVmax = 10.3).
Multiple linear opacities were observed in both lungs.
Scattered cystic lucent opacities were observed in the right upper lobe.
Bilateral pleural thickening was accompanied by nodular FDG uptake, with SUVmax = 8.3; the largest was approximately 1.5 cm in diameter.
Small amounts of pleural effusion were observed bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
Some arterial walls showed calcification.
The cardiac silhouette appeared normal.
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass; FDG uptake was not increased.
The liver has an irregular outline.
CT scan shows multiple mass-like low-density lesions within the liver parenchyma, predominantly in the right lobe, the largest measuring approximately 7.8*6.9cm.
FDG metabolism is increased, SUVmax=15.4.
The boundary between the mass and the right adrenal gland is indistinct; the right adrenal gland is enlarged, with increased FDG metabolism, SUVmax=11.2.
The inferior vena cava is compressed.
The main portal vein is widened.
Multiple enlarged lymph nodes are present near the porta hepatis, in the hepatogastric space, retroperitoneum, and bilaterally in the iliac vessels, the largest with a short diameter of approximately 0.9cm, showing increased FDG metabolism, SUVmax=5.7.
The gallbladder is enlarged, with increased density within the gallbladder; a dense shadow measuring approximately 1.3*0.5*3.0cm is seen in the gallbladder neck.
The pancreas is normal in shape, with no obvious abnormal density shadows seen in the parenchyma; the main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen is enlarged, with no abnormal density or FDG uptake.
Accessory splenic nodules are visible.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
Punctate dense shadows are seen in the left kidney.
The right renal pelvis, calyces, and ureter are not widened.
FDG uptake is not significantly abnormal.
Stomach distension is poor, with no obvious thickening of the stomach wall.
FDG uptake is not significantly abnormal.
Intestinal distension is poor, with continuous FDG metabolism in the colon (SUVmax = 9.6).
The prostate is normal in size and uniform in density, with no abnormally increased FDG uptake.
Bladder distension is normal, with no obvious positive stones.
Calcification of the tunica vaginalis is present in the left testis.
No obvious fluid accumulation is seen in the abdomen or pelvis.
Multiple sites of bone destruction with soft tissue mass formation are observed in the parietal and occipital bones, left clavicle, bilateral scapulae, sternum, bilateral ribs, multiple vertebral bodies and appendages in the spine, sacrum, pelvis, left femoral head, and right femoral neck.
An L5 vertebral fracture is present, with increased FDG metabolism (SUVmax = 13.2).
Some vertebral body margins show osteophyte formation.
Mildly increased FDG metabolism in the right acromioclavicular joint, SUVmax=2.6.

Impression

1. a. Multiple intrahepatic lesions with increased FDG metabolism, suggestive of hepatocellular carcinoma, most likely hepatocellular carcinoma with multiple intrahepatic lesions; please correlate with clinicopathology. Right adrenal metastasis. Involvement of the inferior vena cava and main portal vein. b. Multiple lymph node metastases near the porta hepatis, in the hepatogastric space, retroperitoneum, and bilateral iliac vessels. Diffuse bone metastases throughout the body (see description), pathological fracture of the L5 vertebra. Metastases in both lungs and bilateral pleura.

2. Localized increased FDG metabolism in the left temporal lobe, metastasis to be ruled out; enhanced MRI is recommended. A few ischemic lesions in the deep brain. Age-related brain changes.

3. Gallbladder enlargement with cholestasis. Gallbladder neck stones. Splenomegaly. Accessory spleen. Small kidney stones in the left kidney.

4. Chronic inflammation and sequelae in both lungs. Emphysema in the right upper lobe. Calcification of some arterial walls.

5. Continuous increased FDG metabolism in the colon, suggestive of inflammatory uptake; please correlate with colonoscopy.

6. Calcification of the tunica vaginalis in the left testis.

7. Partial vertebral osteophyte formation. Right shoulder arthritis.

8. Bilateral maxillary sinusitis. Reactive hyperplasia of the bilateral deep cervical space and submandibular lymph nodes.

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.
