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: No obvious space-occupying lesions were observed in the oropharynx and epiglottis following lymphoma treatment; FDG metabolism was normal.
Small lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and left supraclavicular fossa, with short diameters <0.5cm; FDG uptake was normal.
Bilateral axillary lymph nodes were observed; the largest was located on the left side, measuring approximately 0.9*0.7cm, with mild FDG uptake (SUVmax=0.9).
Retroperitoneal and bilateral inguinal lymph nodes were observed; the largest was located beside the abdominal aorta, measuring approximately 0.9*0.8cm, with mild FDG uptake (SUVmax=1.3).
The brain morphology and structure were normal; no abnormal density shadows were observed in the brain parenchyma; FDG uptake was not significantly abnormal.
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 with no obvious abnormalities.
Thickening of the right maxillary sinus mucosa was observed, but no thickening was seen in the mucosa of the other paranasal sinuses, and the sinus walls were intact.
The nasal septum was slightly deviated, but the nasopharyngeal wall was not thickened, 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 parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in shape and structure.
The thyroid gland was normal in shape and size, with slightly uneven density, and FDG uptake was normal.
Both lungs show clear lung markings.
A solid nodule, approximately 0.3 cm in diameter, is present in the posterior segment of the left upper lobe, with no abnormal FDG uptake.
A few calcifications and linear lesions are present in both lungs, with no abnormal FDG uptake.
No pleural thickening is observed bilaterally, and there is no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal, with slightly lower density in the cardiac chambers than the myocardium, and some arteries showing slight sclerosis.
A PICC line is inserted.
The esophagus is not dilated, and the esophageal wall shows no significant thickening or mass; FDG uptake is not increased.
The liver shows no significant abnormalities in shape or size, with smooth liver margins and no widening of the hepatic fissure.
A dense nodule, approximately 0.6 cm in diameter, is present in the right posterior lobe of the liver.
A small cystic lesion, approximately 0.8 cm in diameter, is present at the top of the diaphragm of the liver; FDG uptake is normal.
The main portal vein shows no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
Gallbladder: No abnormalities in shape or size, no thickening of the gallbladder wall, and no abnormalities in local FDG uptake.
Pancreas: Normal shape, no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
Spleen: No abnormalities in shape, size, density, or FDG uptake.
Kidneys: Normal shape and size, no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormalities in FDG uptake.
Bilateral adrenal glands: No obvious abnormalities observed on contrast.
Stomach: Poor filling, slight thickening of the antral wall, slightly increased FDG uptake, SUVmax=2.6.
Intestinal filling: Insufficient, with physiological uptake.
Prostate: Normal size, uniform density, and no abnormally increased FDG uptake.
Bladder: Poor filling, no obvious positive stones observed.
The spinal alignment is normal, with mild osteophyte formation at some vertebral margins and L4/5 and L5/S1 disc bulges.
No abnormalities were observed on imaging of both lower extremities.
Increased FDG uptake in the whole-body bone marrow cavity, SUVmax = 4.1.
Mediastinal blood pool SUVmax = 2.2, liver SUVmax = 3.3, used for Deauville score.

Impression

1. After lymphoma treatment, no obvious space-occupying lesions were found in the oropharynx and epiglottis, and FDG metabolism was normal; multiple small lymph nodes were observed throughout the body, with some showing mild FDG uptake (see description for details). This suggests that tumor activity was suppressed after treatment, and follow-up is recommended. Deauville score: 1 point.

2. Increased FDG metabolism in the bone marrow cavity throughout the body, suggesting reactive proliferative changes; please correlate with clinical findings.

3. Chronic inflammatory micronodules in the upper lobe of the left lung. A few post-inflammatory lesions in both lungs. Mild anemia, and slight arteriosclerosis in some arteries.

4. Calcification in the right lobe of the liver, and a liver cyst.

5. Chronic inflammatory changes in the antrum of the stomach; please correlate with endoscopic follow-up.

6. Mild osteophyte formation in the spine, with L4/5 and L5/S1 intervertebral disc bulges.

7. No obvious abnormalities were found on cranial scintigraphy. 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.
