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, with a few patchy low-density shadows in the deep brain regions, and decreased FDG uptake.
Widening of the ventricles, sulci, fissures, and cisterns, with an enlarged posterior horn of the left ventricle; no midline shift.
Symmetrical eyeballs bilaterally, with no obvious abnormalities.
No thickening of the paranasal sinus mucosa, and intact sinus walls.
No thickening of the nasopharyngeal wall, and no abnormal FDG uptake.
Symmetrical pharyngeal recesses bilaterally, no stenosis of the Eustachian tube openings, normal structures of the infratemporal and pterygopalatine fossae, and clear bilateral parapharyngeal spaces, with no abnormal FDG uptake.
Pharyngeal tonsils bilaterally exhibited physiological uptake.
No abnormalities were observed in the morphology and structure of the laryngopharynx.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
Normal thyroid morphology and size, with slightly uneven density, and no abnormal FDG uptake.
Several small lymph nodes were observed in the bilateral deep cervical spaces and submandibular region, the largest being approximately 0.6 cm in short diameter.
FDG metabolism was normal.
Increased translucency was observed in the upper lobes of both lungs, with multiple cystic lucent shadows in both lungs.
A small ground-glass nodule was observed in the posterior segment of the right lower lobe, with a CT value of approximately -562 HU, a long diameter of approximately 0.3 cm, and relatively clear borders.
FDG metabolism was normal.
Scattered patchy and small nodular shadows were observed in both lungs, with no increased FDG metabolism.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
Some arterial walls showed calcification.
The cardiac silhouette was normal.
No esophageal dilation was observed, and no significant thickening or mass was observed in the esophagus.
FDG uptake was not increased.
The liver has an irregular outline, with dilated intrahepatic bile ducts and obstruction located at the porta hepatis.
An irregular soft tissue mass measuring approximately 4.1*2.8cm is seen at the porta hepatis, showing increased FDG metabolism (SUVmax = 10.5).
Scattered low-density lesions with clear borders and absent FDG uptake are present in the liver; the largest is approximately 1.3cm in long diameter.
The gallbladder is normal in shape and size, with a punctate dense shadow on the gallbladder wall; local FDG uptake is normal.
The pancreas is normal in shape, with calcification in the pancreatic tail; 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, with low-density lesions in both kidneys, and a portion of the left kidney showing high density with clear borders and absent FDG uptake; the largest lesion is located in the right kidney, approximately 3.6cm in diameter.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging is normal.
The stomach was poorly distended, with no obvious thickening of the stomach wall, and no significant abnormalities in FDG uptake.
The intestines were also poorly distended, with no obvious thickening or masses in the intestinal wall, and FDG uptake was physiological.
The prostate was enlarged, approximately 5.6 cm in diameter, with uniform density, and no abnormally increased FDG uptake.
The bladder was generally full, with no obvious positive stones.
Bilateral testicular tunica vaginalis calcifications were observed.
Several lymph nodes were seen adjacent to the pancreatic head, the largest with a short diameter of approximately 1.1 cm, showing increased FDG metabolism (SUVmax = 5.6).
No significant fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment was normal, with some vertebral body margin osteophytes, and L4/5 and L5/S1 intervertebral disc bulges.
Pneumothorax was present in the L4/5 intervertebral disc.
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. Mass in the hepatic hilum, with elevated FDG metabolism, suggestive of hilar cholangiocarcinoma. Metastasis to the parapancreatic lymph nodes is highly probable; further clinical correlation is needed.

2. Bilateral emphysema with bullae. Ground-glass nodule in the posterior segment of the right lower lobe, FDG metabolism normal, suggestive of inflammatory nodule; atypical adenomatous hyperplasia to be ruled out. Annual HRCT follow-up recommended. Scattered chronic inflammation and remnants in both lungs. Partial arterial wall calcification.

3. Hepatic cyst. Gallbladder mural stones. Pancreatic tail calcification.

4. Bilateral renal cysts, with a complex cyst in the left kidney. Benign prostatic hyperplasia. Bilateral testicular tunica vaginalis calcification.

5. Partial vertebral osteophyte formation. L4/5 and L5/S1 intervertebral disc bulge. L4/5 intervertebral disc pneumothorax.

6. A few ischemic lesions deep in the brain. Age-related brain changes. Reactive hyperplasia of bilateral deep cervical and submandibular 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.
