Whole-body 18F-FDG PET/CT scan in a patient with Cholangiocarcinoma 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; 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.
The eyeballs were symmetrical and showed no significant abnormalities.
Slight thickening of the maxillary sinus mucosa was observed bilaterally, but FDG uptake was normal; the remaining paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; the palatine tonsils were symmetrical bilaterally, and FDG uptake was physiological.
The laryngopharynx showed no abnormalities in morphology and structure.
The parotid and submandibular glands showed normal morphology and density, and physiological FDG uptake.
The thyroid gland showed normal morphology and size, uniform density, and no abnormalities in FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
Increased lung markings bilaterally, with a few reticular density increases in the posterior right lung; 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 hilum or mediastinum bilaterally.
The cardiac silhouette was normal.
Calcification was observed in the coronary artery walls.
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was normal.
Bilateral gynecomastia was present.
Post-nasobiliary drainage and pancreatic duct stent placement changes were observed; the common bile duct was not dilated, and no significant space-occupying lesion was observed in the lower segment of the common bile duct.
Mild FDG uptake was observed in the lower segment of the common bile duct (SUVmax = 3.7), with a further slight increase in FDG uptake after a delay (SUVmax = 4.7).
The gallbladder was normal in shape and size, with slightly roughened walls; localized FDG uptake was normal.
Multiple lymph nodes were observed near the gastric antrum, pancreatic head, and retroperitoneum, the largest with a short diameter of approximately 0.7 cm.
FDG uptake was normal.
No significant fluid accumulation was observed in the abdomen or pelvis.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no significant widening, and intrahepatic bile ducts were not dilated.
The pancreas was normal in shape, with unevenly decreased parenchymal density.
The main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no significant abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal glands showed no significant abnormalities on contrast imaging.
The stomach is adequately full, with no obvious thickening of the stomach wall.
Increased FDG uptake is observed in the perigastric nasobiliary drainage area (SUVmax = 6.6).
The intestines are poorly full, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
The prostate is of normal size and uniform density; FDG uptake is not abnormally increased.
The bladder is poorly full, with no obvious positive stones.
The spinal alignment is normal, with some vertebral body margin osteophytes and partial calcification of the nuchal ligament.
Intervertebral disc bulges are present at L2/3, L3/4, L4/5, and L5/S1; FDG uptake is normal.
Atrophy and decreased density are observed in the right buttock, the right thigh muscles (shown in the image), and parts of the left thigh muscles.

Impression

1. a. Post-nasobiliary drainage + pancreatic duct stent placement changes: No dilation of the common bile duct, no obvious space-occupying lesion in the lower segment of the common bile duct, mild FDG metabolism in the course of the lower segment of the common bile duct. Based on pathology and MRI from another hospital, inflammation with local carcinogenesis in the lower segment of the common bile duct is suspected. Please correlate with clinical findings. b. Reactive hyperplasia of the lymph nodes near the gastric antrum, pancreatic head, and retroperitoneum is highly probable. Please follow up. c. Chronic cholecystitis. Pancreatic fat infiltration.

2. Increased local FDG uptake in the course of the nasobiliary drainage tube near the cardia, likely due to inflammation. Please follow up with endoscopic findings.

3. A few aspiration changes in the posterior right lung. Calcification of the coronary artery wall. Bilateral gynecomastia.

4. Spinal degenerative changes. L2/3, L3/4, L4/5, and L5/S1 intervertebral disc bulges. Atrophy with fatty changes in the right buttock, right thigh muscles (shown), and part of the left thigh muscles.

5. No obvious abnormalities were found on cranial scintigraphy. Minor inflammation was observed in both maxillary sinuses.

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.
