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 tomographic images showed: The brain morphology and structure were normal, with widening of the septum pellucidum.
No abnormal density shadows were seen in the brain parenchyma, and FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, with no obvious abnormalities.
The ethmoid sinus mucosa was slightly thickened bilaterally, while the mucosa of the other paranasal sinuses was not thickened, and the sinus walls were intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal fossa and pterygopalatine fossa structures were normal, and the bilateral parapharyngeal spaces were clear, with no abnormal FDG uptake.
Thickening of the right oropharyngeal wall with increased FDG uptake (SUVmax = 10.5); fullness of the base of the tongue and bilateral palatine tonsils with increased FDG uptake (SUVmax = 6.6).
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland was normal in shape and size, with slightly uneven density; FDG uptake was not abnormal.
The right deep cervical lymph node was slightly enlarged, with a short diameter of approximately 1.0 cm; FDG uptake was increased (SUVmax = 5.0).
Multiple solid nodules were found in both lungs, with clear borders.
The largest nodule was located in the posterior basal segment of the left lower lobe, with a diameter of approximately 1.3 cm; FDG uptake was slightly increased (SUVmax = 2.0).
Multiple patchy and linear lesions were found in the subpleural region of both lungs, more prominent in the right lower lobe; FDG uptake was increased (SUVmax = 3.3).
No pleural thickening was seen bilaterally; there was no pleural effusion or pneumothorax bilaterally.
Enlarged lymph nodes measuring approximately 3.9*2.3cm were observed below the carina, with increased FDG uptake (SUVmax = 4.4).
Cardiac findings were normal.
Partial arteriosclerosis was observed.
The esophagus showed no dilation, wall thickening, or mass; FDG uptake was normal.
The liver's shape and size were normal; liver margins were smooth; the hepatic fissure was not widened; plain CT scan showed no abnormal density shadows in the liver parenchyma; FDG uptake was normal.
The main portal vein showed no significant widening; intrahepatic and extrahepatic bile ducts were not dilated.
The gallbladder's shape and size were normal; patchy areas of increased density were observed within the gallbladder; the gallbladder wall was not thickened; localized FDG uptake was normal.
The pancreas was normal in shape; no abnormal density shadows were observed in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
Spleen morphology, size, density, and FDG uptake were normal.
Post-right renal cell carcinoma surgery, a linear dense shadow was seen at the lower pole of the right kidney cortex.
Multiple slightly low-density soft tissue nodules and masses were observed in the renal parenchyma of both kidneys.
The larger one on the right was located at the upper pole of the right kidney, with relatively homogeneous density, a CT value of approximately 27 HU, a size of approximately 3.1*2.6 cm, and increased FDG uptake (SUVmax=3.2).
The more prominent one on the left was located at the upper pole of the left kidney, with less homogeneous density, a CT value of approximately 23 HU, a size of approximately 2.1*2.8 cm, and increased FDG uptake (SUVmax=3.4).
A dense nodule in the left renal calyx was also observed, with a diameter of approximately 0.4 cm.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Multiple small retroperitoneal lymph nodes were observed, the largest with a short diameter of approximately 0.6 cm, and FDG metabolism was normal.
Stomach distension is poor, with slight thickening of the walls of the cardia, part of the gastric body, and antrum.
FDG uptake is slightly increased, SUVmax=3.4.
Intestinal distension is unsatisfactory, with physiological uptake observed; anal canal FDG uptake is increased, SUVmax=5.9.
Prostate size is normal, with calcifications observed; FDG uptake is not abnormally increased.
Bladder distension is poor, with no obvious positive stones observed.
Spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies; L3/4, L4/5, and L5/S1 intervertebral disc bulges.
High-density lesions are present on the left side of the sacrum; FDG metabolism is normal.
FDG uptake is increased bilaterally at the acromioclavicular joints, SUVmax=5.6.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Post-right renal cell carcinoma surgery, changes observed in the right kidney, multiple lesions in both kidneys with increased FDG metabolism, suggestive of malignancy; please correlate with clinical findings and enhanced MRI for diagnosis; left renal calculi. b. Multiple solid nodules in both lungs, well-defined borders, some with slightly increased FDG metabolism, suggestive of chronic inflammatory nodules; metastasis of some larger nodules (posterior basal segment of the left lower lobe) cannot be ruled out; CT follow-up observation is recommended. c. Enlarged subcarinal lymph nodes with increased FDG metabolism, suggestive of metastasis; please correlate with clinical findings.

2. Chronic inflammation and post-inflammatory remnants in both lungs; CT follow-up is recommended. Partial arteriosclerosis.

3. Gallbladder: concentrated bile or residual contrast agent. Prostatic calcification. Reactive hyperplasia of retroperitoneal lymph nodes.

4. Chronic inflammatory changes in part of the gastric wall, hemorrhoidal changes; please follow up with endoscopy.

5. Degenerative changes in the spine, L3/4, L4/5, L5/S1 intervertebral disc bulge. Left sacral islet. Bilateral acromioclavicular joint inflammation.

6. Widened septum pellucidum, no obvious abnormalities seen on cranial scintigraphy. Bilateral chronic ethmoid sinusitis. Inflammation of the right lateral oropharyngeal wall, base of the tongue, and bilateral palatine tonsils. Reactive hyperplasia of right cervical lymph nodes.

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.
