Whole-body 18F-FDG PET/CT scan in a patient with Colon 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:Normal brain morphology and structure.
A solid nodule with a long axis of approximately 1.1 cm was seen in the sellar region, with increased FDG uptake (SUVmax = 20.0).
Punctate low-density shadows were seen in the deep cerebral regions bilaterally, with no significant abnormalities in FDG uptake.
Mild widening of some ventricles, sulci, fissures, and cisterns was observed, with no abnormalities in local density or FDG uptake; no midline shift was observed.
Normal morphology and contour of both eyeballs; clear retrobulbar structures; symmetrical optic nerves bilaterally; no significant abnormalities in FDG uptake.
Thickening of the ethmoid sinus mucosa bilaterally, with intact sinus walls.
No thickening of the nasopharyngeal wall was observed; no stenosis of the bilateral pharyngeal recesses and Eustachian tube openings; normal structures of the bilateral infratemporal fossa and pterygopalatine fossa; clear bilateral parapharyngeal spaces; no abnormalities in FDG uptake.
FDG uptake in the oropharynx and laryngopharynx is physiological.
No abnormal contrast was observed in the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with decreased density and increased FDG uptake (SUVmax = 4.8).
Small lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake is normal.
The thorax is symmetrical, with the mediastinum and trachea in the midline.
Several solid miliary nodules are seen in the upper lobes of both lungs; FDG uptake is normal.
Scattered linear and patchy opacities are seen in both lungs; calcification is seen in the right lower lobe; air-filled cavities are seen in the subpleural regions of both lung apexes; FDG uptake is normal.
Mild pleural thickening is present bilaterally; there is no pleural effusion or pneumothorax.
Multiple lymph nodes are seen in the bilateral hilar regions and mediastinum, the largest with a short diameter of approximately 0.7 cm; some show increased FDG uptake (SUVmax = 3.2).
The cardiac silhouette was normal, and myocardial FDG uptake was normal.
The esophageal wall showed no significant thickening or mass, and FDG uptake was not increased.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
A cystic lesion approximately 5.4 cm in long diameter was observed in the right lobe of the liver, with absent FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder fundus wall was slightly thickened, with nodular high-density shadows within the gallbladder; FDG uptake was normal.
The pancreas's shape was normal, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
The spleen's shape and size were normal, and its density and FDG uptake were normal.
Both kidneys are normal in shape and size.
A slightly high-density nodule with a long diameter of approximately 0.4 cm is seen in the right kidney; FDG uptake is normal.
No widening of the renal pelvis, calyces, or ureters is observed bilaterally; punctate dense shadows are seen in the right renal calyx.
Both adrenal glands are normal in shape and density; FDG uptake is normal.
Poor gastric filling; no significant abnormality in FDG uptake.
Post-treatment for sigmoid colon cancer: Poor bowel preparation; no thickening or mass is seen in the anastomotic wall; FDG uptake is normal.
Thin anterior abdominal wall muscles; intestinal herniation into the subcutaneous tissue is visible.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region.
Small lymph nodes are seen bilaterally inguinally; FDG uptake is normal.
No significant fluid accumulation is seen in the abdomen or pelvic cavity.
The prostate is normal in shape and size; calcifications are seen in the parenchyma; FDG uptake is normal.
The bladder is adequately full, and no obvious stones were found inside.
The spinal alignment is normal, with some vertebral body margin osteophytes, narrowing of the L4-L5 intervertebral space, roughened cortical bone at the relative vertebral body margins, and pneumothorax in the intervertebral discs.
There is bulging of the L2/3 and L3/4 intervertebral discs.
FDG uptake of all bones is normal.

Impression

1. Post-treatment for sigmoid colon cancer: No signs of tumor recurrence were observed in the surgical area; please follow up with colonoscopy. Anterior abdominal wall hernia. Reactive hyperplasia of bilateral inguinal lymph nodes.

2. a. Sellar region mass; enhanced MRI is recommended for further examination. b. Bilateral deep lacunar infarcts, senile encephalopathy. Bilateral ethmoid sinusitis.

3. Chronic inflammatory micronodules in the upper lobes of both lungs, chronic inflammation and sequelae in both lungs, calcification in the lower lobe of the right lung, para-apical emphysema in both lungs. Reactive hyperplasia of hilar and mediastinal lymph nodes in both lungs. Mild pleural thickening on both sides.

4. Liver cyst. Gallstones, chronic cholecystitis. Complex right renal cyst, right renal stones. Prostatic calcification.

5. Spinal degenerative changes. L4/5 vertebral endplate inflammation. L4/5 intervertebral disc pneumatosis and degeneration; L2/3 and L3/4 intervertebral disc bulging.

6. Decreased thyroid density, increased FDG metabolism, suggestive of inflammatory uptake; please follow up with thyroid function tests and ultrasound. Reactive hyperplasia of cervical lymph nodes.

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.
