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: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
The septum pellucidum was widened.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
The right maxillary sinus mucosa was slightly thickened, but the sinus wall was intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, 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.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral 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 seen in the bilateral deep cervical spaces or submandibular region.
Several solid micronodules were observed in both lungs, with a long diameter of approximately 0.2-0.4 cm and clear borders; FDG metabolism was normal.
A few punctate and linear lesions were also seen in both lungs, and punctate calcifications were seen in the lower lobe of the left lung; FDG uptake was normal in all these cases.
No pleural thickening was observed bilaterally, and 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.
No esophageal dilation was observed, and no significant thickening or mass was seen in the esophageal wall; FDG uptake was not increased.
A soft tissue mass measuring approximately 4.4 3.4 cm was observed at the fundus of the gallbladder, infiltrating adjacent liver parenchyma (segments S4 and S5).
FDG metabolism was elevated, with an SUVmax of 8.0.
A soft tissue shadow, approximately 1.0 cm in long diameter, was also observed within the cystic duct, with elevated FDG metabolism and an SUVmax of 3.9.
Multiple enlarged lymph nodes were observed around the porta hepatis and pancreatic head, the largest with a short diameter of approximately 1.5 cm, exhibiting elevated FDG metabolism and an SUVmax of 5.6.
The liver outline was irregular.
Multiple punctate and patchy calcifications were observed within the bile ducts of the left lobe of the liver, and the intrahepatic bile ducts were slightly dilated.
The pancreas appeared normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was not significantly abnormal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Small cystic lesions were observed in both kidneys, approximately 0.4 cm in long diameter, with absent FDG uptake.
No widening of the renal pelvis, calyces, or ureters was observed, and FDG uptake showed no significant abnormalities.
Bilateral adrenal gland imaging showed no significant abnormalities.
Poor gastric distension was observed, but no significant thickening of the gastric wall was observed, and FDG uptake showed no significant abnormalities.
Poor intestinal distension was observed, but no significant thickening or mass was observed in the intestinal wall; FDG uptake was physiological.
The prostate gland was of normal size and shape, with uniform density, and no abnormal FDG metabolism was observed.
The bladder was generally full, and no obvious positive stones were observed.
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 bulging.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. Mass at the gallbladder fundus, with increased FDG metabolism, suggestive of gallbladder cancer involving adjacent liver parenchyma. b. Multiple lymph node metastases around the hepatic hilum and pancreatic head. c. Soft tissue shadow within the cystic duct, with increased FDG metabolism, suggestive of tumor embolism; contrast-enhanced MRI is recommended. d. Multiple stones within the left hepatic lobe bile duct. Slight dilation of intrahepatic bile ducts.

2. Several solid, chronic inflammatory micronodules in both lungs. A few chronic inflammations and old lesions in both lungs. Calcification in the lower lobe of the left lung.

3. Small cysts in both kidneys.

4. Osteophyte formation in the cervical, thoracic, and lumbar vertebrae; L4/5 and L5/S1 intervertebral disc bulges.

5. No obvious abnormalities were found on cranial scintigraphy. Cavity of septum pellucidum (normal variation). Chronic inflammation of the right maxillary sinus.

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.
