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: Normal brain morphology and structure, with punctate, slightly low-density shadows in the deep brain regions; no abnormalities were observed in FDG metabolism.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; no midline shift was observed.
Bilateral eyeballs were symmetrical with no obvious abnormalities.
Thickening of the mucosa of the bilateral ethmoid sinuses and the left maxillary sinus was observed; a cystic shadow with a long diameter of approximately 1.2 cm was seen in the left maxillary sinus.
The mucosa of the remaining paranasal sinuses was not thickened, and the sinus walls were intact.
Nasal septum was deviated; no thickening of the nasopharyngeal wall was observed; both palatine tonsils were symmetrical, and FDG uptake was physiological.
The morphology and structure of the laryngopharynx were normal.
The bilateral parotid and submandibular glands had normal morphology and density, and physiological FDG uptake was observed.
Focal FDG uptake was observed in the right upper alveolar ridge, with SUVmax = 5.5.
The thyroid gland had normal morphology and size, uniform density, and no abnormal FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
Lung markings were clear bilaterally.
Several small solid nodules and plaque-like lesions were observed in the subpleural region of both lungs, the largest being approximately 1.2 cm in long diameter; FDG uptake was normal.
Multiple air-containing cavities were observed bilaterally, along with a few scattered linear lesions; FDG uptake was normal.
A few pleural reactions were observed bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
The cardiac chamber density was lower than that of the myocardium; some arterial walls showed calcification (including the coronary arteries).
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass; FDG uptake was normal.
The liver showed no significant abnormalities in shape or size; the liver margins were smooth, and the hepatic fissure was not widened.
Several small cystic lesions were observed in the right lobe of the liver, the largest being approximately 0.5 cm in diameter; 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 appears normal in shape and size, but the gallbladder wall is thickened, and local FDG uptake is normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma, and the main pancreatic duct is not widened; FDG uptake is normal.
The spleen appears normal in shape, size, density, and FDG uptake.
A soft tissue density nodule adjacent to the spleen, approximately 1.4 cm in diameter, shows normal FDG uptake.
The left kidney is enlarged, with an irregular soft tissue mass in the middle and lower part of the left kidney, approximately 9.2*7.5*9.9 cm in size.
The mass has uneven density, increased FDG uptake (SUVmax=15.6), and invades the left renal calyx and renal sinus.
The left renal vein and inferior vena cava are extensively widened, containing soft tissue density shadows, approximately 14.8*5.5 cm in size, with increased FDG uptake (SUVmax=13.2).
The abdominopelvic fat space is poorly visualized; no obviously enlarged lymph nodes are seen in the abdominopelvic cavity, and there is no fluid accumulation in the abdominopelvic cavity.
The right kidney is normal in shape and size, with a cystic lesion in the right renal parenchyma, approximately 3.3 cm in long diameter, and lacks FDG uptake.
No widening of the right renal pelvis, calyces, or ureter is observed, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no significant abnormalities.
The stomach is adequately filled, with slight thickening of the gastric wall in some areas, and slightly increased FDG uptake (SUVmax = 4.3).
Intestinal filling is unsatisfactory, with a considerable amount of residual contents in the intestinal lumen; no local masses are observed, and FDG uptake is increased in some intestinal segments (SUVmax = 7.3).
The prostate is full, with punctate and patchy dense shadows inside, and no abnormally increased FDG uptake is observed.
There is a small amount of hydrocele in both testes, with calcification on the right side.
The bladder is poorly filled, with no obvious positive stones.
Overall bone density is decreased; the spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, multiple intervertebral disc bulges, and pneumatosis and degeneration of the L4/5 and L5/S1 intervertebral discs.
Bilateral pars interarticularis fracture of the L4 vertebral body, with anterior slippage of the L4 vertebral body.
Whole-body FDG uptake is normal.
Small patchy FDG uptake is observed around the right shoulder, SUVmax = 3.5.

Impression

1. Left renal mass with elevated FDG metabolism, suggestive of renal cell carcinoma; please correlate with clinicopathology; left renal vein and inferior vena cava tumor thrombus formation.

2. Chronic inflammatory nodules in both lungs. Bilateral emphysema, scattered post-inflammatory lesions in both lungs. Minor bilateral pleural reaction. Anemia changes, partial arterial wall calcification (including coronary arteries).

3. Small cyst in the right lobe of the liver. Chronic cholecystitis. Accessory spleen. Right renal cyst. Benign prostatic hyperplasia with calcification. Small amount of hydrocele in both testes, with calcification on the right side.

4. Chronic inflammatory changes in part of the gastric wall and intestines.

5. Osteoporosis, degenerative changes in the spine, multiple intervertebral disc bulges, L4/5 and L5/S1 intervertebral disc pneumodegenerative changes. Bilateral pars interarticularis fracture of the L4 vertebral body, anterior slippage of the vertebral body. Right shoulder periarthritis.

6. Age-related brain, deep lacunar infarcts. Chronic inflammation of both ethmoid sinuses and the left maxillary sinus; submucosal cyst of the left maxillary sinus; right maxillary alveolar ulcer.

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.
