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.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
Both eyes were symmetrical with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was normal.
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.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology and structure.
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.
Lung markings are clear.
Multiple solid nodules and masses of varying sizes are present in both lungs, with clear borders.
The largest is located in the posterior segment of the right lower lobe, measuring approximately 3.4*3.0cm, with increased FDG uptake (SUVmax=5.5).
Scattered linear lesions are present in both lungs, with normal FDG uptake.
No pleural thickening is seen bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes are seen in the bilateral hilar and subcarinal regions, the largest with a short diameter of approximately 2.0cm, showing increased FDG uptake (SUVmax=8.4).
The cardiac silhouette is normal; cardiac chamber density is lower than myocardial density, and some arterial walls (including coronary arteries) show calcification.
No abnormal density shadows were seen in either breast; FDG metabolism was normal.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth liver margins and no widening of the hepatic fissure.
Several cystic lesions were observed in the left lobe of the liver, the largest measuring approximately 7.8 cm in long diameter, with absent FDG uptake.
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 or size, but the gallbladder wall was thickened, and patchy areas of increased density were observed within the gallbladder.
Localized FDG uptake was normal.
The pancreas was normal in shape, with no significant abnormal density 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 a mixed-density mass showing indistinct borders, containing high-density lesions and low-density necrotic areas, measuring approximately 7.8*10.6*12.2cm.
FDG uptake is unevenly increased, SUVmax=11.5, involving the renal pelvis and calyces.
The right renal vein and inferior vena cava are widened with increased FDG uptake, SUVmax=4.7.
A soft tissue nodule in the middle of the left kidney has indistinct borders and uneven density, with patchy high-density shadows at the edges, measuring approximately 2.1*1.8cm, with increased FDG uptake, SUVmax=3.3.
A fat density shadow measuring approximately 1.1*0.9cm is also seen in the middle of the left kidney, with no abnormalities in FDG metabolism.
Retroperitoneal and mesenteric lymph nodes are visible, the largest with a short diameter of approximately 0.8cm, with no abnormalities in FDG metabolism.
Both adrenal glands are enlarged, with no abnormalities in FDG metabolism.
Stomach distension is poor, with slight thickening of the walls of the cardia, part of the gastric body, and antrum.
FDG uptake is increased, SUVmax=2.7.
Intestinal distension is unsatisfactory, with a large amount of residual contents in the intestinal lumen.
FDG uptake in some parts of the intestine is increased, SUVmax=3.2.
Post-operative uterine fibroid surgery, uterus absent.
No obvious abnormalities were seen in the bilateral adnexa.
Bladder distension is poor, with no obvious positive stones.
Multiple osteolytic bone destructions with mass formation in the middle and lower segment of the left humerus and the left scapula, the largest being approximately 3.3*2.5cm in size, located on the left scapula.
FDG uptake is increased, SUVmax=7.9.
Decreased bone density throughout the body, scoliosis, osteophyte formation at the margins of some vertebral bodies, anterior displacement of L4 and L5 vertebral bodies, and multiple intervertebral disc bulges with pneumoconiosis and degeneration.
Subcutaneous calcifications on both buttocks.

Impression

1. a. Right renal mass with increased FDG metabolism, suggestive of renal cell carcinoma with tumor thrombus formation in the right renal vein and inferior vena cava. Please correlate with clinicopathology. Retroperitoneal and mesenteric lymph node metastasis to be ruled out. b. Left renal soft tissue nodule with increased FDG metabolism, renal cell carcinoma to be ruled out. Please correlate with enhanced MRI for comprehensive analysis. Left renal angiomyolipoma. c. Multiple metastatic tumors in both lungs. Multiple lymph node metastases in both hilar and mediastinal regions. d. Metastatic tumors in the left humerus and left scapula.

2. Scattered post-inflammatory lesions in both lungs. Anemic changes, partial arterial wall calcification (including coronary arteries).

3. Left lobe hepatic cyst. Chronic cholecystitis, gallstones. Bilateral adrenal hyperplasia. Post-hysterectomy changes.

4. Chronic inflammatory changes or physiological uptake in parts of the stomach wall and intestines.

5. Osteoporosis, scoliosis, degenerative changes in the spine, anterior slippage of the L4 and L5 vertebrae, multiple intervertebral disc bulges with pneumoconiosis and degeneration. Bilateral subcutaneous calcifications in the buttocks.

6. Age-related brain conditions, deep lacunar infarcts.

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.
