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 patchy low-density shadows in the deep bilateral cerebral regions; no significant abnormalities were observed in FDG uptake.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed 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.
No thickening of the oropharyngeal wall was observed, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and structure.
The parotid and submandibular glands were normal in morphology and density, and FDG uptake was physiological.
The density of the thyroid gland was uneven between the left and right lobes; the right lobe was slightly enlarged, with a slightly low-density nodule approximately 1.6 cm in long diameter, with indistinct borders, and increased FDG uptake (SUVmax = 9.4).
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
Increased lung markings were observed bilaterally.
A patchy ground-glass opacity, approximately 0.8 cm in length, with relatively clear borders, was seen in the apical segment of the right upper lobe; FDG uptake was normal.
Several solid, subsolid, and nodular lesions were also observed in both lungs; the largest, approximately 0.5 cm in length, was located in the lingular segment of the left upper lobe; FDG uptake was normal.
A few linear areas of increased density were observed in the remaining lungs; FDG uptake was normal.
Slight thickening of the pleura was observed bilaterally, with small amounts of pleural effusion in both pleural cavities.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
Calcification of some arterial walls (including the coronary arteries) was observed.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was normal.
The bilateral breasts showed relatively dense fibrous tissue, with no obvious masses or nodules; FDG uptake was normal.
Following PTCD, indwelling catheters were observed communicating with the outside environment in the bile ducts and intrahepatic bile ducts.
Increased FDG uptake was observed along the course of the catheters, with an SUVmax of 8.0.
No definite mass was observed in the common bile duct area.
Intrahepatic bile ducts were dilated.
The gallbladder was small in size, with thickened walls and small patchy areas of increased density within it.
FDG uptake was not abnormally increased.
Several small lymph nodes were observed in the retroperitoneum and bilaterally alongside the iliac vessels, with no abnormal FDG uptake.
No significant fluid accumulation was observed in the abdomen or pelvis.
The liver showed no significant abnormalities in shape or size, with smooth liver margins and no widening of the hepatic fissure.
No significant abnormal density shadows were observed in the liver parenchyma, and FDG uptake was normal.
The main portal vein was not significantly widened.
The pancreas was normal in shape, with a small cystic low-density shadow in the neck of the pancreas, approximately 0.7 cm in length, with clear borders and no FDG uptake.
The main pancreatic duct was not widened.
The spleen showed no abnormalities in shape, size, density, or 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.
The left adrenal gland is slightly enlarged with mildly increased FDG uptake (SUVmax = 3.2); the right adrenal gland shows no obvious abnormalities on contrast.
The stomach is generally full, with slight thickening of the antral wall and increased FDG uptake (SUVmax = 4.6).
The intestines are poorly full, with no obvious thickening or masses in the intestinal wall, and continuous increased FDG uptake in some intestinal segments (SUVmax = 8.9).
The uterus is normal in shape and size, with nodular calcifications in the parenchyma, and no abnormal FDG uptake.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is adequately full, with no obvious positive stones.
The left pubic tubercle shows an irregular shape, unevenly decreased bone density, and increased FDG uptake (SUVmax = 6.6).
Unevenly decreased bone density and increased FDG uptake were observed in the left sacral wing, with an SUVmax of 4.6 and bone fracture.
Scoliosis was present, with decreased bone density in all vertebral bodies, sparse trabeculae, and osteophyte formation at the margins of some vertebral bodies.
Localized depressions were observed at the superior margins of the T12 and L2 vertebral bodies, and bulging discs were observed at L3/4, L4/5, and L5/S1, with no abnormal FDG uptake.
Increased localized FDG uptake was observed around the left hip joint, with an SUVmax of 5.9.

Impression

1. a. Post-PTCD, increased FDG uptake along the indwelling catheter suggests possible post-operative changes, but local tumor uptake cannot be ruled out; no clear space-occupying lesion was seen in the common bile duct area, but intrahepatic bile duct dilation was observed. The above findings should be analyzed in conjunction with enhanced MRI images. b. A metastatic tumor in the left pubic tubercle is highly probable; follow-up is recommended. Reactive hyperplasia of small lymph nodes in the retroperitoneum and bilateral iliac vessels is observed. c. Gallstones or calcifications in the gallbladder, chronic cholecystitis, without clear space-occupying lesions.

2. Uneven density between the left and right lobes of the thyroid gland; slight enlargement of the right thyroid lobe with slightly low-density nodules, increased FDG metabolism, suggesting adenoma; malignancy needs to be ruled out. Further ultrasound examination is recommended, with biopsy if necessary.

3. a. Ground-glass opacity in the apical segment of the right upper lobe, with normal FDG metabolism, suggests chronic inflammatory changes or atypical adenomatous hyperplasia. A follow-up HRCT scan every six months is recommended. b. Chronic inflammatory nodules and nodular lesions in both lungs. A few chronic inflammatory lesions and sequelae in both lungs.

4. Slight thickening of the pleura on both sides, with a small amount of pleural effusion in both pleural cavities.

5. Calcification of some arterial walls (including coronary arteries).

6. Cystic lesions in the neck of the pancreas.

7. Left adrenal hyperplasia.

8. Calcification of the uterus.

9. Slight thickening of the gastric antrum wall with increased FDG metabolism, and increased FDG metabolism in some intestinal segments, suggestive of chronic inflammatory changes or physiological uptake.

10. Osteoporosis, scoliosis with degenerative changes, Schmorl's nodes in the T12 and L2 vertebral bodies.

11. Intervertebral disc bulges at L3/4, L4/5, and L5/S1.

12. Left hip periarthritis.

13. Left sacral wing fracture due to failure.

14. Bilateral deep cerebral ischemic lesions, 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.
