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: Normal brain morphology and structure, with punctate slightly low-density shadows in the deep brain regions; no abnormalities were observed in FDG metabolism.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; no midline shift was observed.
Bilateral eyeballs were symmetrical with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed; the sinus walls were intact.
Increased FDG uptake was observed on the right lateral wall of the nasopharynx (SUVmax = 4.0); bilateral palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and structure.
Bilateral parotid and submandibular glands had normal morphology and density, with physiological FDG uptake.
The thyroid gland was normal in morphology and size, with uniform density; no abnormalities were observed in FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
Both lungs show clear lung markings, multiple reticular changes, increased lung translucency, multiple air-filled cavities, and multiple solid nodules, the largest approximately 0.8 cm in long diameter.
FDG uptake is normal.
Multiple calcifications and linear lesions are present in both lungs, most prominent at the lung apex, with normal FDG uptake.
Bilateral pleural thickening is present, but there is no pleural effusion or pneumothorax.
Multiple small lymph nodes are visible in the hilum and mediastinum, some with calcification, the largest approximately 0.7 cm in short diameter, with increased FDG uptake (SUVmax = 4.3).
A low-density nodule is present in the anterior mediastinum, approximately 1.2 cm in long diameter, with normal FDG metabolism.
The cardiac silhouette is normal.
Calcification is present in some arterial walls (including the coronary arteries).
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
A cystic lesion, approximately 1.2 cm in diameter, was observed in the right posterior lobe of the liver.
Another high-density lesion, approximately 1.0 cm in long diameter, was also observed in the right posterior lobe.
FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape and size, with no thickening of the gallbladder wall and no abnormalities in local FDG uptake.
An irregular, slightly low-density mass, approximately 3.0*3.6cm, was observed in the body of the pancreas, with increased FDG uptake (SUVmax=8.7).
Another slightly low-density lesion, approximately 2.7cm in long diameter, was also seen in the tail of the pancreas, with increased FDG uptake (SUVmax=9.3).
Partial atrophy of the pancreatic tail was observed.
The peripancreatic fat spaces were somewhat blurred.
Multiple peripancreatic lymph nodes were visualized, the largest being approximately 0.8cm in short diameter, with increased FDG uptake (SUVmax=7.4).
Increased density was observed in the greater omentum and mesentery, with multiple small nodules and flocculent shadows, and increased FDG uptake (SUVmax=3.6).
A small amount of pelvic effusion was present.
The spleen showed no abnormalities in morphology, size, density, or FDG uptake.
Both kidneys were normal in morphology and size.
Several cystic lesions were observed in the left renal parenchyma and pelvis, the largest being approximately 3.5cm in long diameter, with absent FDG uptake.
No widening of the renal pelvis, calyces, or ureter was observed, and FDG uptake was not significantly abnormal.
The left adrenal gland is enlarged with increased FDG uptake (SUVmax = 3.1), while the right adrenal gland shows no obvious abnormalities on contrast imaging.
The stomach is adequately full, with slight thickening of the gastric wall in the cardia and antrum, and increased FDG uptake (SUVmax = 3.8).
Intestinal fullness is unsatisfactory; no local masses are seen, but continuous FDG uptake is observed in some intestinal segments (SUVmax = 7.5).
The prostate is full, with punctate dense shadows inside; FDG uptake is not abnormally increased.
The bladder is poorly full, with no obvious positive stones.
Overall muscle uptake is high, overall bone density is decreased, spinal alignment is normal, with some vertebral marginal osteophytes, L4/5 and L5/S1 intervertebral disc bulging, and L4/5 intervertebral disc pneumatosis and degeneration.
Overall skeletal FDG uptake is normal.

Impression

1. a. Massive lesions in the body and tail of the pancreas with elevated FDG metabolism, suggestive of pancreatic cancer with peripancreatic lymph node metastasis. Please combine tumor markers and enhanced MRI for comprehensive analysis. b. Peritoneal seeding metastasis; small amount of pelvic effusion.

2. a. Chronic inflammatory nodules in both lungs. Interstitial changes in both lungs, emphysema with bullae in both lungs, old pulmonary tuberculosis in both lungs. Pleural thickening bilaterally. Chronic inflammatory lymph nodes in the hilum and mediastinum of both lungs. Calcification of some arterial walls (including coronary arteries). b. Low-density nodule in the anterior mediastinum, no abnormalities in FDG metabolism, suggestive of benign nodule, follow-up is recommended.

3. Cyst and calcification in the right lobe of the liver. Hyperplasia of the left adrenal gland. Multiple cysts in the left kidney. Prostatic hyperplasia with calcification.

4. Chronic inflammatory changes in the cardia, antrum of the stomach, and part of the intestine. Please follow up with endoscopy.

5. Osteoporosis, degenerative changes in the spine, L4/5 and L5/S1 disc bulges. L4/5 disc degeneration with pneumoconiosis.

6. Age-related brain conditions, deep lacunar infarcts. Chronic inflammation of the right lateral nasopharyngeal wall.

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.
