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: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
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, with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; FDG uptake was normal; 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 normal.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were observed in the parotid and submandibular glands bilaterally.
The morphology and structure of the laryngopharynx were normal.
Patchy FDG metabolism was observed in the left facial muscles, with SUVmax = 9.1.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
The lung markings are clear.
Several small solid nodules are present in the apical-posterior segment of the left upper lobe, the largest being approximately 0.3 cm in diameter; FDG uptake is normal.
The bronchus in the apical-posterior segment of the left upper lobe is slightly dilated with surrounding calcification and linear foci.
A few linear foci are present in the left upper lobe; FDG uptake is normal.
The left pleura is slightly thickened; there is no pleural effusion or pneumothorax on either side.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal.
Some arterial walls are calcified (including the coronary arteries).
The esophagus is not dilated; the esophageal wall is not significantly thickened or has a mass; 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.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, but a dense nodule was observed within it, with a long diameter of approximately 1.5 cm.
Local FDG uptake was normal.
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.
A soft tissue density nodule was observed adjacent to the spleen, approximately 0.7 cm in diameter, with no abnormal FDG uptake.
A mixed-density mass, approximately 3.7*3.2*3.3cm in size, is seen at the upper pole of the left kidney.
The mass has relatively clear borders and contains low-density lesions.
FDG uptake is slightly increased (SUVmax=2.9).
Another slightly high-density nodule, approximately 2.5*1.9cm in size, with clear borders, is seen in the upper middle part of the left kidney.
FDG uptake is normal.
A cystic lesion, approximately 1.2cm in diameter, is seen at the lower pole of the left kidney.
FDG uptake is absent.
A retroperitoneal lymph node is visualized beside the left aorta, with a short diameter of approximately 0.5cm.
FDG uptake is slightly increased (SUVmax=2.2).
The right kidney is normal in shape and size.
A cystic lesion, approximately 1.2cm in diameter, is seen at the upper pole of the right kidney.
FDG uptake is absent.
No widening of the renal pelvis, calyces, or ureter is observed.
FDG uptake is normal.
Bilateral adrenal gland imaging shows no significant abnormalities.
Stomach distension is poor, with no obvious thickening of the stomach wall, and no significant abnormality in FDG uptake.
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
Prostate size is normal, density is uniform, and FDG uptake is not abnormally increased.
Left inguinal canal is widened, left testis is elevated, bladder distension is adequate, and no obvious positive stones are seen.
Spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulging with pneumoconiosis and degeneration.
Systemic bone marrow FDG metabolism is normal.

Impression

1. A mass in the upper pole of the left kidney with slightly elevated FDG metabolism, highly suggestive of renal cell carcinoma; please correlate with clinicopathology. Reactive hyperplasia of retroperitoneal lymph nodes.

2. Chronic inflammatory micronodules in the upper lobe of the left lung. Slight bronchial dilatation in the upper lobe of the left lung, a few old lesions in the upper lobe of the left lung. Slight thickening of the left pleura, calcification of some arterial walls (including coronary arteries).

3. Gallstones. Accessory spleen. Bilateral renal cysts (including a complex cyst in the left kidney). Possible left inguinal hernia.

4. Degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulge with pneumoconiosis and degeneration.

5. Deep lacunar infarcts in the brain. Physiological uptake of left facial muscles.

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.
