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: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma.
FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
Both eyes were symmetrical, with no obvious abnormalities.
An irregular soft tissue mass was observed in the anterior part of the right nasal cavity, with indistinct borders and uneven density, measuring approximately 5.6*3.4*6.2cm.
FDG uptake was increased, with an SUVmax of 28.4, involving the right ethmoid sinus, maxillary sinus, orbit, and nasal alar.
The right inferior turbinate was not visualized.
Multiple lymph nodes were observed in the right parotid region, bilateral submandibular regions, and bilateral deep cervical spaces.
The largest node, located in the right submandibular region, measures approximately 1.4*0.9cm and shows increased FDG uptake (SUVmax = 5.7).
Thickening of the mucosa was observed in the right frontal, ethmoid, and maxillary sinuses, but the sinus walls remained intact.
No thickening was seen in the nasopharyngeal wall, and FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical, and there was no stenosis at the opening of the Eustachian tubes.
The infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with normal FDG uptake.
Bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the left parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland was normal in shape and size, with slightly uneven density, and FDG uptake was normal.
The lung markings are clear.
A solid nodule is present in the posterior segment of the right lower lobe, the largest being approximately 0.2 cm in diameter.
FDG uptake is normal.
Calcification is present in the anteromedial basal segment of the left lower lobe.
A few linear lesions are present in 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 bilateral hilar and mediastinal regions.
The cardiac silhouette is normal.
The esophagus is not dilated, and the wall is not significantly thickened or swollen.
FDG uptake is normal.
The liver is normal in shape and size, with smooth borders.
The hepatic fissure is not widened.
Liver density is decreased (CT value: 44 HU).
FDG uptake is normal.
The main portal vein is not significantly widened, and there is no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall.
Local FDG uptake is normal.
Pancreas: Normal morphology, decreased parenchymal density, no widening of the main pancreatic duct, and no significant abnormalities in FDG uptake.
Spleen: Normal morphology, size, density, and FDG uptake.
Kidneys: Normal morphology and size, multiple punctate dense shadows in both renal calyces, no widening of the renal pelvis, calyces, or ureters, and no significant abnormalities in FDG uptake.
Adrenal glands: No significant abnormalities observed on imaging.
Stomach: Poor filling, slight thickening of the antral wall, and mildly increased FDG uptake (SUVmax = 2.6).
Intestinal filling: Insufficiently filling, continuous increased FDG uptake in the sigmoid colon (SUVmax = 7.4).
Prostate: Normal size and uniform density, with no abnormally increased FDG uptake.
Bladder: Poor filling, with no obvious positive stones observed.
Retroperitoneal and bilateral inguinal lymph nodes are visible, the largest having a short diameter of approximately 0.7 cm; FDG metabolism is normal.
No significant fluid accumulation is seen in the abdominal or pelvic cavities.
Spinal alignment is normal; whole-body bone mineral density is normal.
Whole-body bone marrow FDG metabolism is normal.
Bilateral lower extremity contrast imaging is normal.
Mediastinal blood pool SUVmax = 2.5, liver SUVmax = 3.7, used for Deauville score.

Impression

1. A mass in the anterior part of the right nasal cavity with increased FDG metabolism, consistent with lymphoma presentation based on the patient's history, involving the right ethmoid sinus, maxillary sinus, orbit, and nasal ala; reactive hyperplasia of the right parotid region, left submandibular region, and bilateral deep cervical spaces is highly probable, with right submandibular lymphoma infiltration to be ruled out. Follow-up is recommended.

2. Chronic inflammatory micronodules in the right lower lobe of the lung. Calcification in the left lower lobe of the lung. A few post-inflammatory remnants in both lungs.

3. Fatty liver. Fatty infiltration of the pancreas.

4. Bilateral renal calculi. Reactive hyperplasia of retroperitoneal and bilateral inguinal lymph nodes.

5. Chronic inflammatory changes or physiological uptake in the gastric antrum and part of the intestine; follow-up with endoscopy is recommended.

6. No obvious abnormalities were found on cranial scintigraphy. Chronic inflammation of the right frontal sinus, ethmoid sinus, and 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.
