Whole-body 18F-FDG PET/CT scan in a patient with Pancreatic 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: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
Both eyes were symmetrical with no obvious 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 normal.
The pharyngeal recesses were symmetrical, 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 showed no abnormalities in morphology and structure.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear bilaterally; several small solid nodules are present in the upper lobes of both lungs and the right middle lobe, the largest being approximately 0.3 cm in diameter; FDG uptake is normal.
Scattered linear lesions are present in both lungs; calcification is present in the posterior segment of the left lower lobe.
The pleura is slightly thickened bilaterally; there is no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal.
Partial arteriosclerosis is present.
The esophagus is not dilated; the esophageal wall is not significantly thickened or swollen; FDG uptake is normal.
An irregular, mass-like soft tissue density shadow, approximately 4.7*4.0*2.8cm in size, was observed around the celiac trunk in the retroperitoneum (L1 level).
The borders were poorly defined, and FDG uptake was increased (SUVmax = 7.4).
The boundary with the adjacent pancreas was indistinct.
No abnormal density shadows were seen in the remaining pancreatic parenchyma.
The main pancreatic duct was slightly visualized.
Retroperitoneal lymph nodes were also visible, the largest with a short diameter of approximately 0.8cm, showing increased FDG uptake (SUVmax = 3.8).
A small amount of pelvic effusion was also observed.
The liver showed no obvious abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
Spleen morphology, size, density, and FDG uptake were normal.
A soft tissue density nodule, approximately 0.8 cm in diameter, was observed adjacent to the spleen; FDG uptake was normal.
Both kidneys were normal in shape and size.
A small cystic lesion, approximately 0.8 cm in diameter, was observed in the lower part of the left kidney; FDG metabolism was normal.
No widening of the renal pelvis, calyces, or ureter was observed; FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no significant abnormalities.
Stomach distension was poor; the walls of the cardia, part of the gastric body, and antrum were slightly thickened; FDG uptake was increased; SUVmax = 3.5.
Intestinal distension was unsatisfactory; intestinal uptake was physiological.
The prostate was normal in shape, with punctate dense shadows observed internally; FDG uptake was not abnormally increased.
Bladder distension was poor; no obvious positive stones were observed.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulging.

Impression

1. A soft tissue mass around the celiac trunk (L1 level) in the retroperitoneum with increased FDG metabolism; multiple retroperitoneal lymph nodes also showing increased FDG metabolism. This is considered a possible malignant tumor with lymph node metastasis. The boundary with the adjacent pancreas is unclear; please rule out other possibilities based on clinical and pathological findings. Pelvic effusion.

2. Chronic inflammatory nodules in both lungs; CT follow-up is recommended. Calcification in the lower lobe of the left lung. A few post-inflammatory remnants in both lungs. Slight pleural thickening bilaterally. Partial arteriosclerosis.

3. Accessory spleen. Small cyst in the left kidney. Calcification in the prostate.

4. Possible chronic inflammatory changes in the gastric wall; please follow up with endoscopy.

5. Degenerative changes in the spine; L4/5 and L5/S1 intervertebral disc bulges.

6. Age-related brain; deep lacunar infarcts.

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.
