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: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and without significant abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was not abnormal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Increased lung markings were observed bilaterally.
Multiple patchy, nodular, and patchy consolidation shadows were seen in the right lung, some showing cystic changes, predominantly in the right upper lobe, with increased FDG metabolism (SUVmax = 3.2).
Multiple solid nodules were seen in the remaining lungs, the largest located in the medial segment of the right middle lobe, with a long diameter of approximately 0.4 cm and clear borders; FDG metabolism was normal.
A few punctate and linear lesions were also seen in both lungs, with normal FDG metabolism.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Several lymph nodes were seen in the bilateral hilar regions, pretracheal spaces, para-aortic arch, aortopulmonary window, and subcarinal region, the largest with a short diameter of approximately 1.0 cm; FDG metabolism was increased (SUVmax = 3.2).
The heart shadow was not enlarged, but a small amount of fluid was seen in the pericardium.
Some arterial walls showed calcification.
The bilateral breasts had relatively dense fibrous glands, with no obvious masses or nodules; FDG metabolism was normal.
The esophagus was not dilated, and the wall was not significantly thickened or lumpy; FDG uptake was not increased.
Gastric filling was poor, with slight thickening of the walls in parts of the gastric body and antrum; FDG uptake was slightly increased (SUVmax = 2.3).
Intestinal filling was unsatisfactory, with increased FDG metabolism in some parts of the intestine (SUVmax = 4.5).
Following palliative surgery for a hepatic hilum lesion and bile duct stent placement, intrahepatic bile ducts were dilated, with some bile ducts filled with gas; multiple irregular patchy and nodular foci of increased FDG metabolism were seen in the liver (SUVmax = 4.5), the largest measuring approximately 2.9 3.0 cm, with lesions predominantly accumulating distal to the bile ducts.
The gallbladder was absent post-cholecystectomy.
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 enlarged, occupying approximately 10 costal units, with no abnormal FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma; the renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The uterus is normal in shape, with no abnormal FDG metabolism.
No abnormal FDG metabolism is seen in the bilateral adnexa.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneum.
No obvious effusion is seen in the abdominal or pelvic cavities.
Increased FDG metabolism is observed in all bone marrow cavities, with SUVmax = 3.2.
The spinal alignment is normal, with some vertebral body margins showing osteophyte formation.
The sacral canal is enlarged, containing a cystic lesion measuring approximately 2.3 1.0 cm, with absent FDG uptake.
The right iliac bone has an irregular shape, but FDG uptake is normal.

Impression

1. a. Postoperative changes following palliative surgery for a space-occupying lesion in the hepatic hilum and bile duct stent placement; dilation of intrahepatic bile ducts, with pneumothorax in some bile ducts; multiple irregular patchy and nodular foci of increased FDG metabolism in the liver, with lesions predominantly accumulating near the distal bile ducts. Considering the medical history, hilar cholangiocarcinoma with intrahepatic metastasis and cholangitis is highly probable. Specialist and MRI follow-up is recommended. b. Splenomegaly; increased FDG metabolism observed in the bone marrow cavity suggests reactive bone marrow hyperplasia.

2. Scattered infectious lesions in the right lung; CT follow-up is recommended. Chronic inflammatory miliary nodules in both lungs. A few chronic inflammations and old lesions in both lungs. Reactive hyperplasia of hilar and mediastinal lymph nodes in both lungs. Small amount of pericardial effusion. Incomplete bilateral mammary regression. Calcification of some arterial walls.

3. Slight thickening of the walls in parts of the gastric body and antrum, with mildly increased FDG uptake, suggestive of chronic gastritis; increased FDG metabolism in parts of the intestines, suggestive of inflammatory or physiological uptake. Follow-up gastroscopy and colonoscopy are recommended.

4. Degenerative changes in the spine. Sacral canal cyst. Irregular morphology of the right iliac bone; please correlate with clinical findings.

5. No obvious abnormalities were found on cranial FDG imaging.

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.
