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, a whole-body PET/CT scan was performed.
The whole-body scan showed: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
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 no obvious abnormalities were observed.
A cystic shadow was seen in the left maxillary sinus, with a long diameter of approximately 1.0 cm; FDG metabolism was not abnormal.
No thickening was observed in the mucosa of the remaining paranasal sinuses, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; FDG uptake was not abnormal; the pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and FDG uptake was not abnormal.
Both palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx are normal.
The thyroid gland is normal in shape and size, with a low-density nodule in the right lobe, approximately 1.1 cm in diameter; FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear bilaterally; multiple solid nodules are present in both lungs, the largest approximately 0.7 cm in diameter; FDG uptake is normal.
Patchy shadows are present in the right lower lobe, and scattered linear lesions are present in both lungs; FDG uptake is normal.
No pleural thickening is observed bilaterally; there is no pleural effusion or pneumothorax bilaterally.
Multiple lymph nodes are seen in the bilateral hilar regions, pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region; the largest has a short diameter of approximately 0.8 cm; FDG uptake is increased, SUVmax = 4.5.
The cardiac silhouette is normal.
Calcification is present in some arterial walls (including the coronary arteries).
No abnormal density shadows were seen in either breast, and FDG metabolism was normal.
No esophageal dilation was seen, and no significant thickening or mass was observed in the esophageal wall; FDG uptake was not increased.
The liver morphology and size were normal, with smooth liver margins, no widening of the hepatic fissure, and decreased liver density (CT value: 37 HU); FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was seen in the intrahepatic or extrahepatic bile ducts.
The gallbladder morphology and size were normal, and the gallbladder wall was not thickened; local FDG uptake was normal.
The pancreas was normal in morphology, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
The spleen morphology, size, density, and FDG uptake were normal.
A mixed-density mass is observed at the lower pole of the left kidney, with indistinct borders and uneven density.
A high-density lesion is seen within, measuring approximately 6.5*5.4*4.9cm.
FDG uptake is increased, with SUVmax=4.4.
Small retroperitoneal lymph nodes are visible, the largest with a short diameter of approximately 0.6cm.
FDG metabolism is normal.
The right kidney is normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureter are not widened.
FDG uptake is normal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly distended, with thickening of the antral wall.
FDG uptake is slightly increased, with SUVmax=2.4.
Intestinal distension is unsatisfactory, with physiological uptake observed.
The uterus has irregular margins.
A cystic lesion, approximately 0.9cm in diameter, is seen within the uterus.
FDG uptake is normal.
Focal FDG uptake is observed in the left adnexal region, with an SUVmax of 6.4 and an uptake diameter of approximately 1.7 cm.
Bladder distension is poor, and no obvious positive stones are seen.
Bone destruction with increased FDG uptake is present in the left 8th anterior rib and left vertebral arch of T9, with an SUVmax of 8.1.
Localized bone defect is present in the right parietal bone, with mildly increased FDG uptake, SUVmax of 1.7.
The spinal alignment is normal, with osteophyte formation at the marginal vertebral bodies of some vertebrae, and L5/S1 disc bulging with pneumoconiosis and degeneration.

Impression

1. a. Left renal mass with increased FDG metabolism, suggestive of renal cell carcinoma; please correlate with clinicopathology. Reactive hyperplasia of small retroperitoneal lymph nodes. b. Metastatic tumors in the left 8th anterior rib and left vertebral arch of T9. Metastatic tumor in the right parietal bone, to be ruled out.

2. Possible chronic inflammatory nodules in both lungs; CT follow-up is recommended to rule out mixed metastases. Chronic inflammation and post-inflammatory remnants in both lungs. Reactive hyperplasia of hilar and mediastinal lymph nodes in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Cystic lesions in the uterus, possibly cystic degeneration of a fibroid; physiological uptake by the left ovary. Ultrasound follow-up is recommended for all of the above.

4. Fatty liver. Chronic inflammatory changes in the antrum of the stomach; please correlate with endoscopic follow-up.

5. Degenerative changes in the spine, L5/S1 intervertebral disc bulge with pneumoconiosis.

6. Low-density nodule in the right lobe of the thyroid gland; FDG metabolism normal; suggestive of an adenoma-like nodule; please confirm with ultrasound examination.

7. Cranial scintigraphy showed no obvious abnormalities. Left maxillary sinus submucosal cyst.

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.
