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; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; local density and FDG uptake were normal; and there was no midline shift.
The bilateral eyeballs had normal morphology and outlines; retrobulbar structures were clear; the bilateral optic nerves were symmetrical; and FDG uptake was normal.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; there was no stenosis in the bilateral pharyngeal recesses or Eustachian tube openings; the infratemporal fossa and pterygopalatine fossa structures were normal; the bilateral parapharyngeal spaces were clear; and FDG uptake was normal.
FDG uptake in the oropharynx and laryngopharynx was physiological.
No abnormal contrast was observed in the bilateral parotid and submandibular glands.
The left lobe of the thyroid gland is absent, and the density of the right lobe is uneven.
FDG uptake is normal.
Multiple lymph nodes are seen in the bilateral deep cervical spaces and supraclavicular regions, the largest with a short diameter of approximately 0.6 cm.
Some have increased FDG uptake, SUVmax = 1.8.
The thoracic cage is symmetrical, with the mediastinum and trachea in the midline.
Multiple solid miliary nodules are seen in the right upper lobe, and calcifications are seen in the left lower lobe.
A few linear shadows are seen in both lungs.
FDG uptake is normal.
No pleural thickening is seen bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
Small lymph nodes are seen in the bilateral hilar and mediastinal regions.
FDG uptake is normal.
The cardiac silhouette is normal, and myocardial FDG uptake is normal.
No significant thickening or mass is seen in the esophageal wall.
FDG uptake is normal.
The bilateral breasts are normal in shape, with no abnormal density shadows in the fibrous glands.
FDG uptake is normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
A cystic lesion with a long diameter of approximately 0.5 cm was observed in the right posterior lobe of the liver, with no abnormal FDG uptake.
The main portal vein showed no obvious widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape and size, with no thickening of the gallbladder wall, no positive stones or obvious masses, and no abnormal FDG uptake.
The pancreas showed no abnormalities in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no abnormal FDG uptake.
The spleen showed no abnormalities in shape and size, density, or FDG uptake.
Accessory splenic nodules were observed around the spleen.
Both kidneys showed no abnormalities in shape and size; a cystic lesion with a long diameter of approximately 0.9 cm was observed in the right kidney, with no abnormal FDG uptake.
A roughly round, low-density lesion measuring approximately 4.7*3.9*5.5cm was observed adjacent to the left renal pelvis.
The cyst wall was slightly thickened, resembling a wall nodule, with internal septa.
FDG uptake at the periphery was slightly increased (SUVmax=1.9), and the renal calyces showed compression.
No widening of the right renal pelvis, calyces, or ureter was observed, and no positive stones were found.
A slightly low-density nodule measuring approximately 1.8*1.5cm was observed in the right adrenal gland, with increased FDG uptake (SUVmax=2.4).
No abnormalities were observed in the left adrenal gland.
Stomach distension was poor, with increased FDG uptake in parts of the gastric wall (SUVmax=2.3).
Bowel preparation was poor; no obvious mass was observed in the intestinal wall, but increased FDG uptake was observed in parts of the intestinal tract (SUVmax=6.0).
The uterus was normal in shape, with no abnormal density shadows and normal FDG uptake.
No abnormal density or FDG uptake was observed in the bilateral adnexa.
The bladder was poorly filled, but no positive stones or obvious masses were observed.
Small lymph nodes were seen in the retroperitoneum; FDG uptake was normal.
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies and L3/4 and L4/5 intervertebral disc bulging.
FDG uptake of all bones was normal.

Impression

1. Low-density mass near the left renal pelvis with slightly increased FDG metabolism at the periphery, suggestive of a neoplastic lesion, with cancer as the primary consideration. Further enhanced MRI analysis is recommended. Reactive hyperplasia of retroperitoneal lymph nodes.

2. Chronic inflammatory micronodule in the right upper lobe, calcification in the left lower lobe, and fibrosis in both lungs. Follow-up with CT scan is recommended. Reactive hyperplasia of hilar and mediastinal lymph nodes.

3. Liver cyst. Accessory spleen. Right renal cyst. Right adrenal adenoma.

4. Increased FDG metabolism in part of the gastric wall and intestinal tract, suggestive of physiological uptake or chronic inflammation. Follow-up with endoscopy is recommended.

5. Cervical, thoracic, and lumbar spondylosis. L3/4 and L4/5 intervertebral disc bulge.

6. Absence of the left thyroid lobe; please consider clinical history. Reactive hyperplasia of bilateral deep cervical interspace and supraclavicular lymph nodes.

7. 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.
