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: Brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was normal.
Slight widening of the sulci, fissures, and cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; FDG uptake was normal; the pharyngeal recesses were symmetrical bilaterally; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and FDG uptake was normal.
FDG uptake of the oropharynx and laryngopharynx was normal.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
FDG metabolism was normal.
Multiple solid nodules were observed in both lungs, with relatively clear borders.
The largest nodule had a long diameter of approximately 0.3 cm.
A few streaks were observed in the lower lobes of both lungs.
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 bilateral hilar and mediastinal regions.
Calcification was observed in the walls of the aorta and coronary arteries.
A round, low-density shadow with indistinct borders, approximately 5.7 4.9 cm, was observed in the hepatic hilum.
FDG uptake was increased, with an SUVmax of 5.8.
Intrahepatic bile duct dilation was also observed.
Multiple slightly low-density nodules were observed in the liver, with relatively clear borders.
The largest nodule was located in the left lateral lobe, with a long diameter of approximately 2.1 cm.
FDG uptake was increased, with an SUVmax of 4.4.
Several lymph nodes were observed in the porta hepatis, the largest with a short diameter of approximately 1.0 cm.
FDG uptake was increased, with an SUVmax of 5.8.
The gallbladder was atrophied, but FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was normal.
The spleen's shape, size, density, and FDG uptake were normal.
A small splenic nodule was observed around the spleen, but FDG uptake was normal.
A cystic lesion was observed in the left kidney, with a long diameter of approximately 4.8 cm.
FDG uptake was normal.
The right kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureter were not widened, and FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
No esophageal dilation, no obvious thickening or mass in the esophageal wall, and no increased FDG uptake.
Poor gastric filling, no obvious thickening of the gastric wall, and no significant abnormality in FDG uptake.
Slight thickening of the rectosigmoid junction wall, increased FDG uptake, SUVmax=5.6, uptake range approximately 2.71.3cm.
Normal prostate size, with punctate calcifications, and no abnormally increased FDG uptake.
Normal bladder filling, with no obvious positive stones.
No obvious fluid accumulation in the abdomen or pelvis.
Post-operative right inguinal hernia surgery, no increased FDG uptake in the surgical area.
Normal spinal alignment, with osteophyte formation at some vertebral margins, L4/5 and L5/S1 intervertebral disc bulging, and pneumothorax within the L5/S1 intervertebral disc, and no abnormal FDG uptake.
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. Mass in the hepatic hilum, with increased FDG uptake and intrahepatic bile duct dilation, suggestive of cholangiocarcinoma; intrahepatic metastasis; hilar lymph node metastasis.

2. Multiple chronic inflammatory micronodules in both lungs, with a few post-inflammatory lesions in the lower lobes of both lungs. Calcification of some arterial walls (including coronary arteries).

3. Accessory spleen. Left renal cyst. Prostatic calcification. Postoperative changes after right inguinal hernia surgery.

4. Slight thickening of the rectosigmoid junction wall with increased FDG uptake, suggestive of possible inflammation or physiological changes; endoscopic re-examination is recommended to rule out other possibilities.

5. Spinal osteophyte formation. L4/5 and L5/S1 intervertebral disc bulge, L5/S1 disc pneumatosis and degeneration.

6. Mild age-related brain changes.

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.
