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 no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
There was no widening of the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and without significant abnormalities.
The mucosa of the bilateral maxillary and ethmoid sinuses was thickened, but FDG uptake was normal, and the sinus walls were intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The palatine tonsils were slightly enlarged bilaterally, with increased FDG uptake (SUVmax = 5.7).
The laryngopharynx was normal in morphology and structure.
The parotid and submandibular glands were normal in morphology and density, with physiological FDG uptake.
The thyroid gland was normal in morphology and size, with uniform density, and no abnormalities in FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
Increased lung markings were observed bilaterally, with a few linear opacities and punctate foci in both lungs; FDG uptake was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was not increased.
The liver's shape and size were normal; the liver margins were smooth, and the hepatic fissure was not widened.
A cystic low-density lesion, approximately 1.5 cm in long diameter, with clear borders, was observed in the left medial lobe of the liver on plain CT scan; FDG uptake was absent.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder's shape and size were normal; the gallbladder wall was not thickened, and local FDG uptake was normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is normal.
The spleen's shape, size, density, and FDG uptake are normal.
A small nodule with a long diameter of approximately 1.1 cm is seen at the anteromedial border of the spleen; FDG uptake is normal.
An irregular mass is seen at the lower pole of the left kidney, the largest measuring approximately 3.6*2.6*3.8 cm in cross-section.
FDG uptake is at background levels, with an SUVmax of 2.2, involving the renal calyces and pelvis.
Several small lymph nodes with a short diameter of approximately 0.2-0.4 cm are seen in the retroperitoneum; FDG uptake is normal.
The perirenal fascia is slightly thickened bilaterally; FDG uptake is normal.
Cystic low-density shadows are also seen in both kidneys; the larger one is located at the upper pole of the right kidney, with a long diameter of approximately 2.5 cm, clear borders, and absent FDG uptake.
No hydronephrosis or dilation of the renal pelvis, calyces, or ureters was observed bilaterally.
A nodular high-density shadow was seen in the right renal calyx, with a long diameter of approximately 1.0 cm.
Bilateral adrenal gland imaging showed no obvious abnormalities, and FDG uptake was normal.
No significant fluid accumulation was observed in the abdomen or pelvis.
The stomach was adequately filled, with no significant thickening of the gastric wall.
Mild FDG uptake was observed in some parts of the gastric wall (SUVmax = 2.4).
The intestines were poorly filled, with no significant thickening or mass in the intestinal wall.
FDG uptake was increased in some intestinal segments (SUVmax = 4.4).
Focal FDG uptake was observed in the anus (SUVmax = 8.1).
The prostate was enlarged, with an anteroposterior diameter of approximately 4.0 cm.
Punctate calcifications were observed within the prostate parenchyma, but FDG uptake was not abnormally increased.
The bladder was adequately filled, with no obvious positive stones.
The spinal alignment was normal, with some vertebral marginal osteophytes.
L4/5 disc bulge, L5/S1 disc herniation, FDG uptake showed no abnormalities.

Impression

1. a. A mass in the lower pole of the left kidney involving the renal calyces and pelvis, with FDG showing background metabolism. Combined with contrast-enhanced CT images from another hospital, this is considered a malignant tumor, most likely renal cell carcinoma. Please confirm with pathology. b. Reactive hyperplasia of small retroperitoneal lymph nodes. Slight thickening of the perirenal fascia bilaterally. c. Bilateral renal cysts, right renal calculus.

2. A few post-inflammatory lesions in both lungs.

3. Liver cysts. Accessory splenic nodules. Benign prostatic hyperplasia with calcification.

4. Increased FDG metabolism in parts of the stomach wall and intestines, likely due to chronic inflammation. Please follow up with endoscopy. Hemorrhoidal changes, please correlate with clinical findings.

5. Spinal degenerative changes. L4/5 disc bulge, L5/S1 disc herniation.

6. Cranial scintigraphy showed no obvious abnormalities. Bilateral maxillary sinusitis and ethmoid sinusitis. Bilateral chronic palatine tonsillitis.

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.
