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, extending from the top of the skull to the upper thigh.
The scan showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed 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 and showed no significant abnormalities.
Slight thickening of the right maxillary sinus mucosa was observed, but the sinus wall was intact.
No thickening was observed in the nasopharyngeal wall; no abnormalities were observed in FDG uptake.
Both pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; both parapharyngeal spaces were clear; and no abnormalities were observed in FDG uptake.
No abnormalities were observed in FDG uptake of the oropharynx and laryngopharynx.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density; and no abnormalities were observed in FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake was normal.
Multiple focal air-containing cystic cavities were observed in the upper lobes of both lungs, some of which coalesced to form bullous opacities.
Scattered patchy and small opacities were observed in the upper lobes of both lungs; calcification was visible on the right side.
Cystic dilatation of the bronchi in the left upper lobe was observed.
Multiple solid nodules and scattered linear opacities were also observed in both lungs; FDG uptake was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
The liver showed no significant abnormalities in shape or size; the liver margins were smooth, and the hepatic fissures were not widened.
No significant abnormal density shadows were observed in the liver parenchyma on plain CT scan; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was of acceptable shape, with increased density in the lumen; FDG uptake was normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are 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 abnormalities in FDG uptake.
Both adrenal glands show no obvious abnormalities on contrast.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or swollen; FDG uptake is not increased.
The stomach is poorly distended, the gastric wall is not significantly thickened, FDG uptake is increased, and SUVmax = 3.1.
The walls of the middle and upper rectum are thickened, with localized masses measuring approximately 3.2cm 2.4cm and 5.0cm in diameter.
FDG uptake is increased, with an SUVmax of 23.6.
Multiple lymph nodes are observed in the perirectal space, beside the bilateral common iliac vessels, and retroperitoneum, the largest with a short diameter of approximately 2.2m.
FDG uptake is increased, with an SUVmax of 12.6.
FDG uptake is continuously increased in the remaining colon and rectum, with an SUVmax of 8.9.
The prostate is of normal size and homogeneous density, with no abnormally increased FDG uptake.
The bladder is generally full, with no obvious positive stones.
A small amount of fluid density is seen in the tunica vaginalis of both testes.
The L4 vertebral body is slightly displaced anteriorly, the spinal alignment is normal, and there is osteophyte formation at the margins of some vertebral bodies.
The L3/4, L4/5, and L5/S1 intervertebral discs are bulging, with no abnormal FDG uptake.
Osteophyte formation with cystic changes in the right facet joint of L4/5, with increased FDG uptake and SUVmax=4.3.

Impression

1. a. Thickening of the rectal wall in the middle and upper segments, with increased FDG metabolism, suggestive of rectal cancer. Multiple lymph node metastases in the perirectal space, bilateral common iliac vessels, and retroperitoneum. b. Continuous increased FDG metabolism in the remaining colon and rectum, suggestive of inflammation or physiological changes; endoscopic follow-up is recommended.

2. Emphysema and bullae in the upper lobes of both lungs, old tuberculous lesions in the right upper lobe, bronchiectasis in the left upper lobe, multiple chronic inflammatory micronodules in both lungs, and scattered post-inflammatory lesions in both lungs.

3. Chronic gastritis; endoscopic follow-up is recommended.

4. Cholestasis in the gallbladder; ultrasound follow-up is recommended. Small amount of hydrocele in both testes.

5. Mild anterior slippage of the L4 vertebral body. Spinal osteophyte formation. L3/4, L4/5, and L5/S1 intervertebral disc bulging. Degenerative changes with inflammatory metabolism in the right L4/5 facet joint are the primary consideration; CT follow-up is recommended to rule out other possibilities.

6. No obvious abnormalities were found on cranial imaging. Right maxillary 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.
