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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
Increased FDG metabolism was observed in both palatine tonsils, with SUVmax = 8.6.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Several scattered air-filled sacs were seen in the subpleural region of the upper lobes of both lungs.
Several solid micronodules were seen in both lungs, approximately 0.2-0.4 cm in long diameter, with clear borders; FDG metabolism was normal.
A few punctate and linear lesions were also seen in both lungs; FDG metabolism was normal.
No pleural thickening was seen bilaterally; there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
Some arterial walls showed calcification (including the coronary arteries).
The esophagus was not dilated; the esophageal wall was not significantly thickened or swollen; FDG uptake was not increased.
The liver has an irregular outline, and the intrahepatic bile ducts are dilated, resembling soft vines, converging towards the porta hepatis.
A soft tissue mass measuring approximately 3.6 4.1 cm is seen in the bile duct region of the porta hepatis, with increased FDG metabolism (SUVmax = 10.3).
Slightly enlarged lymph nodes are seen around the pancreatic head, with a short diameter of approximately 0.8 cm, showing increased FDG uptake (SUVmax = 3.1).
The gallbladder is normal in shape and size, with a rough wall and a ring-shaped dense shadow within the lumen, with a long diameter of approximately 0.6 cm.
FDG uptake is normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is normal.
The spleen is normal in shape, size, density, and FDG uptake.
A cystic lesion was seen in the right kidney, approximately 2.4 cm in long diameter, with absent FDG uptake.
The left kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
No widening of the renal pelvis, calyces, or ureter was observed, and FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
The stomach was poorly distended, with no obvious thickening of the stomach wall and no obvious abnormalities in FDG uptake.
The intestines were poorly distended, with continuous FDG metabolism increased in parts of the colon and rectum, SUVmax=5.6.
The prostate was full in shape, approximately 5.1 cm in transverse diameter, with punctate calcifications inside, and no abnormal FDG metabolism was observed.
The bladder was generally distended, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdomen, pelvis, or retroperitoneal region.
No significant fluid accumulation was seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Mass in the hepatic hilum, increased FDG metabolism, intrahepatic bile duct dilation, suggestive of hilar cholangiocarcinoma. b. Reactive hyperplasia of the lymph nodes around the pancreatic head is highly probable, metastasis to be ruled out. No signs of distant metastasis were observed systemically.

2. Several small, solid, chronic inflammatory nodules in both lungs. A few chronic inflammations and old lesions in both lungs. Emphysema and bullae in the upper lobes of both lungs. Calcification of some arterial walls (including coronary arteries).

3. Chronic cholecystitis. Gallstones. Right renal cyst. Benign prostatic hyperplasia with calcification.

4. Continuous increased FDG metabolism in parts of the colon and rectum, likely due to inflammatory uptake; colonoscopy follow-up is recommended.

5. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

6. 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.
