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: The 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.
A cystic shadow, approximately 1.6 cm in long diameter, was seen in the left maxillary sinus; the mucosa of the remaining 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.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
Thyroid gland shape and size are normal, density is slightly uneven, FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces and submandibular region.
Increased lung markings, multiple solid nodules in both lungs with clear borders, the largest approximately 1.7cm in diameter, FDG uptake is increased, SUVmax=1.8, scattered patchy, linear lesions in both lungs, FDG uptake is normal.
Pleural thickening bilaterally, no pleural effusion or pneumothorax bilaterally.
No obvious enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
Cardiac silhouette is normal.
Pericardial thickening with a small amount of effusion, cardiac chamber density is lower than myocardial density, some arterial walls are calcified (including coronary arteries).
Dense mammary gland tissue bilaterally, soft tissue nodule below the left nipple, approximately 1.8cm in diameter, calcification foci in the right breast, FDG metabolism is normal.
No esophageal dilation, no obvious thickening or mass in the esophageal wall, and no increased FDG uptake.
No obvious abnormalities in liver shape and size, smooth liver margins, no widening of the hepatic fissure, a low-density nodule at the top of the diaphragm, approximately 2.3 cm in diameter, with increased FDG uptake (SUVmax = 2.4).
No obvious widening of the main portal vein, and no dilation of intrahepatic or extrahepatic bile ducts.
No abnormalities in gallbladder shape and size, no thickening of the gallbladder wall, and no abnormalities in local FDG uptake.
Normal pancreas shape, no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
No abnormalities in spleen shape, size, density, or FDG uptake.
A soft tissue density nodule adjacent to the spleen, approximately 1.5 cm in diameter, with no abnormal FDG uptake.
The right kidney is enlarged, with a large, mixed-density mass of indistinct borders, measuring approximately 16.0*12.9*18.1cm.
The density is heterogeneous, containing low-density necrotic areas and high-density foci.
FDG uptake is unevenly increased (SUVmax=3.4).
Flocculent shadows are seen around the mass.
Adjacent stomach wall, intestines, pancreatic head, and abdominal aorta are compressed and displaced to the left.
Retroperitoneal lymph nodes are visible, the largest with a short diameter of approximately 1.0cm, showing slightly increased FDG uptake (SUVmax=1.8).
FDG metabolism in the right renal vein and inferior vena cava is normal.
The left kidney is normal in shape and size, with multiple cystic lesions in the left renal parenchyma, the largest approximately 2.0cm in diameter.
FDG uptake is absent.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is normal.
The right adrenal gland is poorly visualized.
The left adrenal gland is enlarged with increased FDG uptake (SUVmax=1.8).
Stomach distension is poor, with a significant amount of residual contents.
No obvious thickening of the stomach wall is observed, and FDG uptake is normal.
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall.
FDG uptake is physiological.
Uterus is small, with no abnormal density shadows observed, and FDG uptake is normal.
No obvious abnormalities are observed in the bilateral adnexa.
Bladder distension is poor, with no obvious positive stones observed.
Decreased bone density throughout the body, normal spinal alignment, with osteophyte formation at the margins of some vertebral bodies and multiple lumbar disc bulges.
Fluid density shadows are seen in the sacral canal, and subcutaneous calcifications are present in the right buttock.
No abnormalities are observed in FDG metabolism in the bone marrow throughout the body.

Impression

1. a. Right renal mass with increased FDG metabolism, suggestive of renal cell carcinoma; reactive hyperplasia of retroperitoneal lymph nodes, follow-up recommended to rule out mixed metastases. b. Multiple lung metastases. Liver metastases are highly probable; enhanced MRI analysis recommended. c. No clear tumor thrombus findings in the right renal vein and inferior vena cava; enhanced CT scan recommended.

2. Scattered chronic inflammation and remnants in both lungs. Bilateral pleural thickening. Pericardial thickening with a small amount of effusion, anemia changes, and calcification of some arterial walls (including coronary arteries).

3. Bilateral breast hyperplasia; fibroadenoma possible in the left breast, calcification in the right breast; ultrasound examination recommended.

4. Accessory spleen. Left adrenal hyperplasia. Multiple cysts in the left kidney.

5. Osteoporosis, degenerative changes in the spine, multiple lumbar disc herniations. Sacral canal cyst. Subcutaneous calcification in the right buttock.

6. Age-related brain conditions, deep lacunar infarcts. Submucosal cyst in the left maxillary sinus.

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.
