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: The brain morphology and structure were normal, with small patchy low-density shadows in the right basal ganglia region, showing absent FDG uptake.
The ventricular system was enlarged, with widening of the sulci, fissures, and cisterns.
The ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, with no obvious abnormalities.
The mucosa of the bilateral maxillary and ethmoid sinuses was thickened, but the sinus walls were intact.
The nasopharyngeal walls were not thickened, and FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear, with no abnormal FDG uptake.
The bilateral palatine tonsils showed physiological uptake.
The laryngopharynx morphology and structure were normal.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The thyroid gland shows uneven density in the left and right lobes, with low-density nodules visible within.
The left lobe is enlarged and spherical, approximately 3.0 2.7 cm, with partial loss of FDG uptake in the left lobe.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region; FDG metabolism was normal.
Scattered multiple linear opacities were observed in both lungs; FDG uptake was normal.
Bilateral pleural thickening was present, but there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
Partial calcification was observed in the walls of the aorta and coronary arteries.
No esophageal dilatation, significant wall thickening, or masses were observed; FDG uptake was not increased.
The liver margins are not smooth, the liver lobe proportions are disproportionate, the hepatic fissure is widened, the left lobe margin is bulging, and large patchy, nodular, and mass-like low-density shadows are seen within the liver, with increased FDG uptake.
The largest shadow measures approximately 11.3 7.4 cm, with an SUVmax of 24.6.
Focal FDG uptake is observed in the left branch of the portal vein at the porta hepatis, with an SUVmax of 7.9; focal FDG concentrations are also seen in the hepatic vein and inferior vena cava near the right atrium, with an SUVmax of 13.5.
The gallbladder is absent post-operatively, and local FDG uptake is normal.
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 abnormalities in FDG uptake.
The spleen is slightly enlarged, with no abnormalities in density or FDG uptake.
A small cystic lesion, approximately 0.5 cm in long diameter, was observed in the left kidney; no abnormal FDG uptake was observed.
The right kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma; no widening of the renal pelvis, calyces, or ureter was observed; no obvious abnormal FDG uptake was observed.
Bilateral adrenal gland imaging showed no obvious abnormalities.
The stomach was poorly filled; no obvious thickening of the stomach wall was observed; no obvious abnormal FDG uptake was observed.
The intestines were poorly filled; no obvious thickening or mass was observed in the intestinal wall; FDG uptake was physiological.
The prostate was of acceptable shape, with punctate dense shadows observed internally; no abnormally increased FDG uptake was observed.
The bladder was generally full; no obvious positive stones were observed internally.
Enlarged lymph nodes were observed around the head of the pancreas, with a long diameter of approximately 3.1 cm and increased FDG metabolism (SUVmax = 11.5).
Multiple small lymph nodes were also observed in the retroperitoneum, the largest with a short diameter of approximately 0.4 cm and increased FDG metabolism (SUVmax = 1.8).
A small amount of pelvic effusion was observed, with increased FDG metabolism (SUVmax = 2.8).
A small amount of fluid-density shadow was observed within the tunica vaginalis of both testes.
The L2 vertebral body showed mild posterior displacement, with osteophyte formation at some vertebral margins.
Calcification was visible in the nuchal ligament.
The T12-L1 vertebral bodies showed wedge-shaped deformity with localized kyphosis.
Pneumothorax was observed in the T10/11 and T11/12 intervertebral discs, with no abnormal FDG uptake.
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. a. Multiple intrahepatic lesions with elevated FDG metabolism, suggestive of malignancy, most likely hepatocellular carcinoma with intrahepatic metastasis; tumor thrombus formation near the right atrium in the left portal vein, hepatic vein, and inferior vena cava; peripancreatic lymph node metastasis; small amount of pelvic effusion. b. Cirrhosis, slightly enlarged spleen. Reactive hyperplasia of small retroperitoneal lymph nodes.

2. A few post-inflammatory lesions in both lungs. Bilateral pleural thickening. Partial calcification of the aorta and coronary artery walls.

3. Absence after cholecystectomy. Small cyst in the left kidney. Calcification lesion in the prostate. Small amount of hydrocele in both testes.

4. Low-density nodules in both lobes of the thyroid gland, with enlargement of the left lobe and local FDG metabolism loss in the left lobe, suggestive of nodular goiter; ultrasound and thyroid function tests are recommended.

5. Spinal degenerative changes. T12-L1 vertebral body wedge deformity with localized kyphosis, L2 vertebral body instability. T10/11 and T11/12 intervertebral disc pneumoconiosis.

6. Right basal ganglia softening lesion, age-related brain changes. Bilateral maxillary and ethmoid sinusitis.

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.
