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 not significantly abnormal.
There was no widening of the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, and no significant abnormalities were observed.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was not abnormal.
The 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.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx were normal in morphology and structure.
Patchy FDG uptake was observed in the glottic region, with SUVmax = 8.8.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No obviously enlarged lymph nodes were seen bilaterally in the neck.
Lung markings are clear bilaterally; several solid nodules with clear borders are present in the upper and middle lobes of the right lung, the largest being approximately 0.3 cm in diameter; FDG uptake is normal.
Multiple air-filled cavities are present bilaterally; scattered linear lesions are present bilaterally; small calcifications are present in the lower lobe of the left lung; FDG uptake is normal.
Partial pleural thickening is present bilaterally; no pleural effusion or pneumothorax is present bilaterally.
Lymph nodes are visible in the hilar region, pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region; the largest has a short diameter of approximately 0.7 cm; FDG uptake is increased, SUVmax = 3.6.
Cardiac silhouette is normal.
Partial arteriosclerosis is present.
Esophageal dilatation is not seen; no obvious thickening or mass is seen in the esophageal wall; 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 small cystic lesion, approximately 0.3 cm in diameter, was observed near the top of the diaphragm in the right lobe of the liver; FDG uptake was normal.
The main portal vein showed no significant 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 and no abnormalities in local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
The right kidney is enlarged with irregular margins.
An irregular, mixed-density mass is present in the upper middle part of the right kidney, with indistinct borders and uneven density.
A low-density lesion measuring approximately 8.7*6.6*9.9cm is seen within the mass.
FDG uptake is unevenly increased, with an SUVmax of 7.8, involving the right renal pelvis and calyces.
Small retroperitoneal lymph nodes are visible, the largest with a short diameter of approximately 0.7cm.
FDG metabolism is normal.
The left kidney is normal in shape and size.
A cystic lesion in the left renal parenchyma, approximately 1.1cm in diameter, is present.
FDG uptake is absent.
High-density shadows are seen in the renal pelvis, calyces, ureter, and bladder.
FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging is normal.
The stomach is poorly distended, with no significant thickening of the stomach wall.
FDG uptake is normal.
The intestine is poorly distended, with no significant thickening or mass in the intestinal wall.
FDG uptake is physiological.
The prostate is of normal size and uniform density, and no abnormal increase in FDG uptake was observed.
The spinal alignment is normal, with mild osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulges.
Systemic bone marrow FDG metabolism was normal.

Impression

1. Right renal mass with increased FDG metabolism, renal cell carcinoma is suspected; enhanced MRI is recommended to rule out benign tumors. Reactive hyperplasia of retroperitoneal lymph nodes.

2. Chronic inflammatory micronodules in the right lung; follow-up CT is recommended. Bilateral emphysema, scattered post-inflammatory lesions in both lungs, small calcification in the lower lobe of the left lung. Partial pleural thickening bilaterally. Reactive hyperplasia of hilar and mediastinal lymph nodes bilaterally. Partial arteriosclerosis.

3. Small liver cyst. Left renal cyst. Residual contrast agent in the urinary tract.

4. Mild vertebral osteophyte formation. L4/5 and L5/S1 intervertebral disc bulge.

5. No obvious abnormalities on cranial scintigraphy. Physiological uptake in the glottic region.

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.
