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 with both arms raised, from the top of the skull to the upper thighs: The brain morphology and structure were normal, with no abnormal density shadows seen in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
Slight thickening of the bilateral ethmoid sinus mucosa was observed, while the mucosa of the remaining paranasal sinuses was not thickened, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall, and FDG uptake was normal.
The bilateral 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 abnormalities in FDG uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx were normal in morphology and structure.
The thyroid gland was normal in morphology and size, with slightly uneven density; a low-density nodule approximately 0.6 cm in diameter was observed in the left lobe, with no abnormalities in FDG uptake.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Lung markings were clear bilaterally.
A solid nodule with clear borders, approximately 0.3 cm in diameter, was observed in the posterior segment of the left upper lobe; no abnormal FDG uptake was seen.
A few linear lesions were observed in both lungs; FDG uptake was also 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 appeared normal.
The cardiac chamber density was slightly lower than that of the myocardium, and some arteries showed slight sclerosis.
Several small nodules with clear borders, approximately 0.4 cm in diameter, were observed in the right breast; FDG uptake was normal.
No abnormal density shadows were observed in the left breast; FDG metabolism was normal.
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass; FDG uptake was not increased.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
Slightly low-density lesions were observed in the left medial lobe and right anterior lobe, the larger one located in the left medial lobe measuring approximately 3.3cm 2.5cm with a CT value of approximately 40 HU.
FDG showed background uptake.
A small cystic lesion, approximately 0.4cm in diameter, was observed in the left lateral lobe of the liver; FDG uptake was normal.
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 and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormal FDG uptake.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
The stomach is poorly filled, with slight thickening of the walls of the cardia, part of the gastric body, and antrum, and mildly increased FDG uptake (SUVmax = 2.6).
Irregular thickening of the mid-rectum wall with increased FDG uptake is observed (SUVmax = 13.3, SUVmax = 18.2 after delayed contrast imaging).
The thickened area is approximately 2.4 cm, with a length of approximately 5.4 cm.
The intestinal lumen is narrowed, but the serosal surface is relatively smooth.
Small presacral lymph nodes are visible, the largest with a short diameter of approximately 0.5 cm; FDG uptake is normal.
A small amount of pelvic fluid is present.
The uterine margin is not smooth, but FDG uptake is normal.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly filled, but no obvious positive stones are seen.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies and L4/5 and L5/S1 intervertebral disc bulging.
FDG uptake of all bones is normal.

Impression

1. Irregular thickening of the mid-rectal wall with elevated FDG metabolism, suggestive of rectal cancer based on medical history. Reactive hyperplasia of small presacral lymph nodes, close observation recommended to rule out metastasis. Small amount of pelvic effusion.

2. Chronic inflammatory micronodule in the upper lobe of the left lung, follow-up CT recommended. A few post-inflammatory lesions in both lungs. Mild anemia, slight arteriosclerosis in some arteries.

3. Small nodule in the right breast, FDG metabolism normal, suggestive of hyperplastic nodule or fibroadenoma, follow-up ultrasound recommended.

4. Small cyst in the left lateral lobe of the liver, hemangioma in the left medial lobe and right anterior lobe of the liver is the first consideration, please combine with MRI. Uterine fibroid.

5. Chronic inflammatory changes in part of the gastric wall, please combine with endoscopy.

6. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge.

7. Low-density nodule in the left lobe of the thyroid, FDG metabolism normal, suggestive of adenomatous nodule, please combine with ultrasound.

8. No obvious abnormalities seen on cranial scintigraphy. Bilateral chronic ethmoid sinusitis.

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.
