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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed the following: Brain morphology and structure were normal, with punctate low-density shadows in the deep cerebral regions bilaterally; FDG uptake showed no significant abnormalities.
Some ventricles, sulci, fissures, and cisterns showed widening, but local density and FDG uptake were normal; midline shift was not observed.
The morphology and contours of both eyeballs were normal; retrobulbar structures were clear; optic nerves were symmetrical bilaterally; FDG uptake showed no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed; sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; there was no narrowing of the bilateral pharyngeal recesses and Eustachian tube openings; the bilateral infratemporal fossa and pterygopalatine fossa structures were normal; bilateral parapharyngeal spaces were clear; FDG uptake was normal.
FDG uptake in the oropharynx and laryngopharynx was physiological.
No abnormal contrast was observed in the bilateral parotid and submandibular glands.
Slightly low-density nodules are seen in both lobes of the thyroid gland, the largest measuring approximately 2.6*1.8cm in the right lobe, with indistinct borders and increased FDG uptake at the periphery (SUVmax=4.1).
Small lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, and submental region, with normal FDG uptake.
Multiple pure ground-glass nodules, approximately 0.3-0.4cm in long diameter, are seen in the left upper lobe and right lower lobe, with partially indistinct borders; FDG uptake is normal.
Multiple solid miliary nodules are seen in both lungs, and air-filled cavities are seen in the subpleural region of both upper lobes; FDG uptake is normal.
No pleural thickening is seen bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
Multiple slightly high-density lymph nodes are seen in the bilateral hilar regions and mediastinum, the largest approximately 1.0cm in short diameter, with increased FDG uptake (SUVmax=4.9).
The cardiac silhouette is normal, and myocardial FDG uptake is normal.
Partial calcification of arterial walls (including coronary arteries).
Increased FDG uptake in the esophagus (SUVmax = 4.5).
Post-common bile duct stent placement: Increased FDG uptake in the bile ducts surrounding the upper end of the stent at the porta hepatis (SUVmax = 6.3), with intrahepatic bile duct dilation and pneumoconiosis.
No abnormal density shadows or abnormal FDG uptake were observed in the remaining liver parenchyma.
The gallbladder was not clearly visualized.
An irregular soft tissue density shadow with indistinct borders was seen in the head of the pancreas, with increased FDG uptake (SUVmax = 10.7), measuring approximately 3.8 x 2.6 cm, and its boundaries with the celiac trunk, superior mesenteric artery, and posterior splenic vessels were unclear.
The body and tail of the pancreas were relatively normal in morphology, and no significant dilation of the main pancreatic duct was observed.
Multiple lymph nodes were seen in the hepatogastric space, retroperitoneal para-aortic space, mesenteric space, and para-descending aorta, the largest with a short diameter of approximately 1.0 cm, showing increased FDG uptake (SUVmax = 7.2).
A small amount of fluid was observed in the pelvic cavity.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys showed no abnormalities in shape or size, and no obvious abnormal density shadows were seen in the renal parenchyma; FDG uptake was normal.
No widening of the renal pelvis, calyces, or ureters was observed; nodular dense shadows were seen in the right renal calyx, the upper segment of the left ureter, and the right ureterovesical inlet.
Both adrenal glands were enlarged, with increased FDG uptake (SUVmax = 4.2).
Gastric distension was poor; the gastric wall at the cardia and antrum was slightly thickened, with the thickest point approximately 1.7 cm; FDG uptake was increased (SUVmax = 6.2).
Bowel preparation was poor; no obvious masses were seen in the intestinal wall; FDG uptake was increased in parts of the intestine and anus (SUVmax = 6.6).
The prostate gland appeared normal in shape and size, with a transverse diameter of approximately 4.7 cm.
Calcifications were observed in the prostate tissue.
FDG uptake was normal.
The bladder was poorly filled, but no obvious positive stones were found.
The L4 vertebral body was slightly displaced anteriorly, with osteophyte formation at some vertebral margins.
There was a bulging L2-S1 intervertebral disc and partial pneumothorax in the thoracolumbar intervertebral discs.
The nuchal ligament was calcified.
FDG uptake of all bones was normal.

Impression

1. a. An irregular soft tissue mass in the head of the pancreas, with increased FDG metabolism, suggests a malignant tumor, possibly pancreatic cancer, but metastasis cannot be ruled out. The boundary with adjacent blood vessels is unclear. Metastasis is present in the hepatogastric space, retroperitoneal para-aortic lymph nodes, mesenteric space, and para-aortic lymph nodes. b. Post-choledochal stent placement, increased FDG metabolism in the bile ducts surrounding the upper end of the stent in the porta hepatis suggests possible inflammatory changes, with neoplastic lesions to be ruled out. Intrahepatic bile duct dilation and pneumoconiosis are present. The gallbladder is not clearly visualized. Pelvic effusion is present. Please combine the above with tumor markers, enhanced MRI, and MRCP for comprehensive analysis.

2. A mass in the cardia, it is recommended to combine with the pathology report of an external gastroscopy; chronic inflammation of the gastric antrum. Discontinuous esophageal FDG metabolism is present, but physiological uptake should be considered in conjunction with an external gastroscopy report. 3.a. Pure ground-glass nodules in the left upper lobe and right lower lobe, with normal FDG metabolism, suggestive of chronic inflammatory nodules or atypical adenomatous hyperplasia. Please combine with annual HRCT follow-up. b. Chronic inflammatory micronodules (solid) in both lungs, paraseptal emphysema in both upper lobes, please combine with CT follow-up. Reactive hyperplasia of hilar and mediastinal lymph nodes in both lungs. Partial arteriosclerosis (including coronary arteries).

3. Right kidney stone, bilateral ureteral stones. Prostatic calcification, please combine with PSA follow-up. Bilateral adrenal hyperplasia is highly probable.

4. Increased FDG metabolism in some intestinal segments, suggestive of physiological uptake or chronic inflammation, hemorrhoidal changes, please combine with endoscopy follow-up.

5. Spinal degenerative changes. Mild anterior slippage of L4 vertebral body. L2-S1 intervertebral disc bulge, with partial pneumothorax and degeneration of the thoracolumbar intervertebral discs.

6. Bilateral deep lacunar infarcts, age-related brain changes.

7. Low-density thyroid nodules, with increased FDG metabolism at the margins of some nodules, suggesting possible nodular goiter; ultrasound follow-up is recommended. Reactive hyperplasia of cervical lymph nodes.

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.
