Whole-body 18F-FDG PET/CT scan in a patient with Lymphoma 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; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no significant abnormalities.
Following treatment for nasal lymphoma, no significant space-occupying lesions were observed in the nose; FDG metabolism was normal; the left pharyngeal recess was slightly shallow.
Thickening of the mucosa of the bilateral ethmoid and maxillary sinuses was observed; the mucosa of the remaining paranasal sinuses was not thickened, and the sinus walls were intact.
The palatine tonsils were symmetrical, and FDG uptake was physiological.
The morphology and structure of the laryngopharynx were normal.
The morphology and density of the bilateral parotid and submandibular glands were normal, and FDG uptake was physiological.
The thyroid gland was normal in shape and size, with uniform density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
The lung markings are clear, with a few linear lesions in the subpleural region of the upper lobes of both lungs; FDG uptake is normal.
No pleural thickening is observed bilaterally, and there is no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes are seen in the hilum or mediastinum bilaterally.
The cardiac silhouette is normal, with cardiac chamber density lower than myocardial density.
A port-a-catheter is inserted in the right anterior chest wall.
The esophagus is not dilated, and the esophageal wall shows no significant thickening or mass; FDG uptake is not increased.
The liver is full, with decreased liver parenchymal density (CT value approximately 9 HU); diffusely increased FDG uptake is observed in the liver (SUVmax = 8.2).
A catheter is seen in the bile duct; intrahepatic bile duct effusion is present; the gallbladder is enlarged, and the gallbladder wall is slightly thickened.
The pancreas is swollen with surrounding effusion and diffusely increased FDG uptake (SUVmax = 11.2).
The spleen is slightly enlarged; density and FDG uptake are normal.
Both kidneys are normal in shape and size, with dense nodules in both renal calyces.
No widening of the renal pelvis, calyces, or ureters was observed, and FDG uptake was not significantly abnormal.
Bilateral adrenal soft tissue nodules and masses, approximately 4.3*3.7cm in size, showed increased FDG uptake (SUVmax=6.1).
The stomach was adequately filled, with a considerable amount of residual contents; the stomach wall was not thickened, and FDG uptake was normal.
Intestinal filling was unsatisfactory; no local masses were observed, but localized FDG uptake was increased in the right lower quadrant of the intestine (SUVmax=6.9).
The prostate was of normal size and uniform density, and FDG uptake was not abnormally increased.
The bladder was poorly filled, and no obvious positive stones were observed.
Multiple lymph nodes were visible in the bilateral retrodiaphragmatic spaces, hepatogastric space, and retroperitoneum; the largest, located retroperitoneally, measured approximately 1.5*1.0cm, and showed increased FDG uptake (SUVmax=4.8).
Pelvic effusion was present.
The spinal alignment was normal, and overall bone density was normal.
No abnormalities were observed in the whole-body skeletal FDG uptake.
No abnormalities were observed in the imaging of both lower extremities.
Mediastinal blood pool SUVmax=1.5, liver SUVmax=8.2, Deauville score: 5.

Impression

1. a. After treatment for nasal lymphoma, no obvious FDG metabolism elevation foci were observed in the nose, suggesting suppressed tumor activity. b. Diffuse FDG metabolism elevation in the liver; pancreatic swelling with surrounding effusion and FDG metabolism elevation; bilateral adrenal gland lesions with FDG metabolism elevation; multiple lymph nodes in the bilateral posterior diaphragmatic crura, hepatogastric space, and retroperitoneum showing FDG metabolism elevation. All of the above suggest lymphoma infiltration, and follow-up examination after treatment is recommended.

2. A few post-inflammatory lesions in both lungs. Anemia. Right anterior chest wall port-a-cath placement.

3. Fatty liver. Post-cholecystectomy changes, intrahepatic bile duct pneumothorax, chronic cholecystitis. Slightly enlarged spleen. Bilateral renal stones. Pelvic effusion.

4. Possible physiological uptake or chronic inflammatory changes in the right lower abdomen, lymphoma infiltration to be ruled out, please follow up.

5. No obvious abnormalities were seen on cranial scintigraphy. Chronic inflammation of bilateral ethmoid and maxillary 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.
