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: a few punctate low-density shadows in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma, and FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, 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.
The laryngopharynx showed no abnormalities in morphology or structure.
The parotid and submandibular glands showed no abnormal density shadows bilaterally.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
No enlarged lymph nodes were seen bilaterally in the neck, and FDG metabolism was normal.
Several solid micronodules, approximately 0.2-0.3 cm in length, with clear borders, were observed in both lungs; FDG metabolism was normal.
A few linear and punctate lesions were also observed in both lungs; FDG metabolism was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
Calcification of some arterial walls (including the coronary arteries) was observed.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was not increased.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissure.
A cystic lesion, approximately 1.3 cm in length, was observed in the right posterior lobe of the liver; FDG uptake was absent.
No significant abnormal density shadows were observed in the remaining liver parenchyma; FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall; local FDG uptake was normal.
Pancreatic fat infiltration was observed, with no widening of the main pancreatic duct and no significant abnormalities in FDG uptake.
The spleen showed no abnormalities in morphology, size, density, or FDG uptake.
A mixed-density mass measuring approximately 7.7 7.9 cm was observed in the left renal parenchyma, with increased FDG metabolism (SUVmax = 7.9).
Several cystic lesions, approximately 2.5 cm in long diameter, were observed in both kidneys, with absent FDG uptake.
Spotted and nodular dense shadows were observed in both renal calyces.
Bilateral adrenal gland contrast imaging showed no significant abnormalities.
The stomach was poorly distended, with no significant thickening of the gastric wall and no significant abnormalities in FDG uptake.
The intestines were poorly distended, with no significant thickening or mass in the intestinal wall, and FDG uptake was physiological.
The prostate was of normal size, with punctate calcifications and no abnormally increased FDG uptake.
The bladder was generally distended, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region, and FDG metabolism was normal.
No obvious fluid accumulation was observed in the abdomen or pelvic cavity.
The spinal alignment was normal, with some vertebral body margin osteophytes, and L4/5 and L5/S1 intervertebral disc bulging.
FDG uptake was normal.
No abnormal FDG metabolism was observed in the entire skeleton.

Impression

1. a. Left kidney mass with increased FDG metabolism, suggestive of renal cell carcinoma; please correlate with clinicopathology. b. Multiple renal cysts in both kidneys. Renal stones in both kidneys.

2. Several small, solid, chronic inflammatory nodules in both lungs; regular CT scans are recommended to rule out other involvement. Minor chronic inflammation and old lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Liver cysts. Fatty infiltration of the pancreas. Prostatic calcification.

4. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

5. A few ischemic lesions in the deep bilateral brain regions, suggestive of senile encephalopathy.

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.
