Whole-body 18F-FDG PET/CT scan in a patient with Renal 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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
The nasal septum was deviated, but the nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, 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 palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
The lung markings are clear.
An irregular patchy nodule, approximately 1.6*1.4*cm in size, is present in the subpleural region of the lateral basal segment of the right lower lobe, with increased FDG uptake (SUVmax=11.2).
Several ground-glass nodules are present in the subpleural region of the apical segment of the right upper lobe, the apical-posterior segment of the left upper lobe, the posterior segment of the right lower lobe, and the lateral segment of the right middle lobe, the largest being approximately 0.5cm in long diameter, with a maximum CT value of -570HU; FDG uptake is normal.
Multiple solid nodules are present in both lungs, the largest approximately 0.4cm in diameter; FDG uptake is normal.
A few linear lesions are present in both lungs; FDG uptake is normal.
Right pleural thickening is present; there is no pleural effusion or pneumothorax bilaterally.
Right hilar lymph nodes were observed; the largest had a short diameter of approximately 1.6 cm, with increased FDG uptake (SUVmax = 6.7).
The cardiac silhouette appeared normal, with cardiac chamber density lower than myocardial density.
A port-a-cath was inserted in the right anterior chest wall.
Both breasts showed dense glandular tissue with no abnormal density shadows; FDG metabolism was normal.
The esophagus showed no dilation, but FDG uptake was increased throughout its wall (SUVmax = 4.5).
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Several small cystic lesions, approximately 0.5 cm in diameter, were observed within the liver; FDG uptake was normal.
The main portal vein showed no significant dilation, and intrahepatic and extrahepatic bile ducts were not dilated.
The pancreas appeared normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was normal.
Spleen morphology, size, density, and FDG uptake were normal.
Soft tissue density nodules adjacent to the spleen, the largest approximately 2.0 cm in diameter, showed no abnormal FDG uptake.
Following treatment for a malignant tumor in the right kidney, a large, irregular, mixed-density mass was observed in the right kidney, with indistinct borders and uneven density.
Low-density necrosis areas and patchy high-density lesions were seen within the mass, measuring approximately 15.1*13.3*21.5 cm.
FDG uptake was unevenly increased, SUVmax=28.0.
The mass was poorly demarcated from the right adrenal gland, gallbladder, and adjacent liver, and encased the inferior vena cava.
Extensive thickening of the liver capsule, greater omentum, mesentery, and pelvic floor fascia was observed with nodules and patchy shadows, showing increased FDG uptake, SUVmax=15.9.
Pelvic effusion was present.
Multiple enlarged retroperitoneal lymph nodes were observed, the largest approximately 1.0 cm in short diameter, showing increased FDG uptake, SUVmax=10.6.
The left kidney is normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
The left adrenal gland shows no obvious abnormalities on contrast imaging.
The stomach is poorly filled, with no obvious thickening of the stomach wall, and FDG uptake is not significantly abnormal.
The intestines are poorly filled, with increased FDG uptake in some sections, SUVmax=3.7.
The uterus is normal in shape and size, with no abnormal density shadows seen, and FDG uptake is not abnormal.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly filled, with no obvious positive stones.
Multiple vertebral bodies and appendages of the sternum, pelvic bones, and the upper right femur show multiple areas of bone destruction with increased FDG uptake, SUVmax=6.5, most pronounced in the upper right femur, measuring approximately 2.5*2.3*3.4cm.

Impression

1. a. Right renal malignancy followed by treatment, with a mass in the right kidney accompanied by increased FDG metabolism, suggesting high tumor activity. b. Peritoneal seeding metastasis, pelvic effusion. Multiple retroperitoneal lymph node metastases. c. Right lower lobe lung metastasis, with a high probability of right hilar lymph node metastasis. d. Multiple bone metastases throughout the body (see description for details).

2. a. Several ground-glass nodules in both lungs, with normal FDG metabolism, suggesting possible inflammation; follow-up CT scan recommended. b. Chronic inflammatory micronodules in both lungs. A few post-inflammatory remnants in both lungs. Right pleural thickening. Anemia changes; right anterior chest wall port inserted.

3. Bilateral breast hyperplasia.

4. Small liver cysts. Accessory spleen.

5. Chronic inflammatory changes or physiological uptake in the entire esophagus and part of the intestine; please follow up with endoscopy.

6. No obvious abnormalities were found on cranial scintigraphy.

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.
