Whole-body 18F-FDG PET/CT scan in a patient with Gallbladder Cancer 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:Following treatment of brain metastases, punctate low-density shadows were observed in the deep cerebral regions and brainstem bilaterally, with 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.
The bilateral ethmoid sinus mucosa was slightly thickened, with no abnormalities in FDG uptake; the sinus walls were intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The bilateral palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx showed no abnormalities in morphology or structure.
The bilateral parotid and submandibular glands had normal morphology and density, and FDG uptake was physiological.
The thyroid gland was normal in morphology 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.
Lung markings were clear bilaterally; a 0.4cm solid micronodule was observed in the right lung horizontal fissure, with no abnormal FDG uptake.
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.
The heart was not enlarged.
Some arterial walls showed calcification.
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was not increased.
Following comprehensive treatment for gallbladder cancer, multiple metal clips were observed in the surgical area, with no abnormally increased FDG uptake.
Slight local dilation of intrahepatic bile ducts was observed.
No significant effusion was observed in the abdominal or pelvic cavities.
The liver's shape and size are normal, with smooth borders and no widening of the hepatic fissures.
CT scan shows small cystic low-density shadows in both lobes of the liver, the largest being approximately 0.8 cm in length, with clear borders and absent FDG uptake.
No other abnormal density shadows are seen in the liver parenchyma, and FDG uptake is not abnormally increased.
The main portal vein is not significantly widened.
The pancreas shows mild atrophy, with no widening of the main pancreatic duct, and no significant abnormality in FDG uptake.
The spleen's shape, size, density, and FDG uptake are normal.
Both kidneys are normal in shape and size.
Several cystic low-density shadows are seen in both kidneys, the largest being in the left kidney, approximately 1.6 cm in length, with clear borders and absent FDG uptake.
No widening of the renal pelvis, calyces, or ureters is seen bilaterally.
Bilateral adrenal gland imaging shows no significant abnormalities, and FDG uptake is not abnormal.
Stomach fullness is normal, with no obvious thickening of the stomach wall.
FDG uptake is slightly increased in some areas of the stomach wall (SUVmax = 3.6).
Intestinal fullness is poor, with slight thickening of the rectal wall and increased FDG uptake (SUVmax = 4.9).
The prostate is enlarged, with a transverse diameter of approximately 5.0 cm.
FDG uptake is uneven (SUVmax = 2.1).
Bladder fullness is poor, with no obvious positive stones observed.
An irregular, slightly low-density mass is seen in the right quadratus femoris muscle, measuring approximately 7.2*4.4 cm.
The mass has uneven density, scattered calcifications, and indistinct borders, particularly with the adjacent femur.
FDG uptake is increased (SUVmax = 14.4).
Enlarged lymph nodes and soft tissue nodules are seen bilaterally near the external iliac vessels, in the right groin, and anterior to the left pubic bone.
The largest lymph node has a short diameter of approximately 1.4 cm.
FDG metabolism is increased (SUVmax = 17.7).
No significant abnormalities were observed in FDG uptake of the remaining lower extremities.
The spinal alignment was normal, with some vertebral body margins showing osteophyte formation, and some thoracic and lumbar vertebrae exhibiting decreased FDG uptake.
Partial calcification was observed in the nuchal ligament.
Patchy areas of increased density were seen at the relative margins of the L5/S1 vertebral bodies, but FDG uptake was normal.

Impression

1. a. Changes after comprehensive treatment for gallbladder cancer; no clear signs of tumor recurrence were observed in the surgical area. Slight local dilation of intrahepatic bile ducts. b. Right quadratus femoris muscle metastasis, enlarged compared to previous scan. Multiple metastases near bilateral external iliac vessels, right inguinal region, and left anterior pubic region (newly added).

2. a. After treatment for brain metastases, no clear space-occupying lesions were observed in the brain; lacunar ischemic lesions in the deep cerebral region and brainstem bilaterally, characteristic of senile brain changes. b. Liver cyst; no obvious abnormal density shadows were observed in the remaining liver parenchyma; no abnormal increase in FDG metabolism was observed. Please follow up with enhanced MRI for the above findings.

3. Benign prostatic hyperplasia; uneven FDG metabolism; please combine PSA and MRI for comprehensive analysis.

4. Chronic inflammatory micronodules in the right lung horizontal fissure. Calcification of some arterial walls.

5. Mild pancreatic atrophy. Multiple renal cysts.

6. Mildly increased FDG metabolism in some gastric walls; slight thickening of the rectal wall with increased FDG metabolism, suggestive of physiological uptake or chronic inflammatory changes; please follow up with endoscopy.

7. Decreased FDG metabolism in some thoracic and lumbar vertebrae, suggestive of post-radiotherapy changes. Spinal degeneration. L5/S1 vertebral endplate inflammation.

8. Minor inflammation of bilateral ethmoid sinuses.

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.
