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 hands 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.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; no abnormalities were observed in FDG uptake; the pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally; and no abnormalities were observed in FDG uptake.
No abnormalities were observed in FDG uptake in 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 solid nodules were observed in both lungs, with relatively clear borders; the largest nodule had a long diameter of approximately 0.4 cm.
Scattered linear shadows were also observed in both lungs; FDG uptake was normal.
The pleura was slightly thickened bilaterally, but 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.
An oval-shaped low-density shadow with relatively clear borders was observed in the subcutaneous intermuscular region of the right shoulder, with a long diameter of approximately 6.2 cm and a CT value of approximately -110 HU; FDG uptake was normal.
The liver showed no significant abnormalities in shape or size; the liver margins were smooth; the hepatic fissure was 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 was not significantly widened; no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was of acceptable shape; the intraluminal density was partially increased, but local FDG uptake was normal.
The pancreas is normal in shape, with no obvious abnormal density shadows seen in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size.
Two cystic lesions are visible in the left kidney, with relatively clear borders and a long diameter of approximately 1.5 cm.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal glands show no obvious abnormalities on contrast imaging.
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, and some FDG uptake is increased (SUVmax = 2.5).
The rectal wall in the upper and middle segment is thickened, with the thickest point approximately 1.5 cm.
The boundary with the adjacent sigmoid colon is indistinct.
FDG uptake is increased, with SUVmax = 19.5 and delayed SUVmax = 24.7.
Multiple lymph nodes are seen in the surrounding fat spaces and presacral region, the largest with a short diameter of approximately 0.4 cm.
Some have mildly increased FDG uptake, with SUVmax = 1.8.
The prostate is of normal size and uniform density, with no abnormally increased FDG uptake.
The bladder is generally full, with no obvious positive stones.
No obvious fluid accumulation is seen in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral body margin osteophytes, partially increased bone density in the L3-4 vertebral bodies, and L3/4 and L4/5 intervertebral disc bulging, with no abnormal FDG uptake.
No abnormal FDG uptake is observed in any of the bones examined.

Impression

1. a. Thickening of the rectal wall in the upper and middle segment, involving the adjacent sigmoid colon; increased FDG metabolism, with further increased metabolism after delay, consistent with rectal cancer. b. Metastasis to the surrounding fat spaces and presacral lymph nodes is highly probable; please correlate with clinicopathology.

2. Multiple chronic inflammatory micronodules in both lungs; scattered post-inflammatory remnants in both lungs. Slight thickening of the pleura bilaterally. Lipoma in the subcutaneous intermuscular region of the right shoulder.

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

4. Cholestasis in the gallbladder; ultrasound follow-up is recommended. Left renal cyst.

5. Spinal osteophyte formation. L3-4 vertebral endplate inflammation. L3/4 and L4/5 intervertebral disc bulge.

6. No obvious abnormalities were seen on cranial imaging. Bilateral 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.
