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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed: Multiple lymph nodes in the bilateral retropharyngeal spaces, right submandibular region, and left deep cervical space; the largest was located in the left retropharyngeal space, measuring approximately 1.5*1.1cm, with increased FDG uptake (SUVmax=9.0).
Multiple lymph nodes in the right hilum, mediastinum (pretracheal, post-vena cava, para-aortic arch, aortopulmonary window, subcarinal), cardiophrenic angle, and prediaphragmatic group; the largest was located in the right hilum, measuring approximately 2.6*2.1cm, with increased FDG uptake (SUVmax=9.5).
Multiple lymph nodes in the hepatic hilum, retroperitoneal region, peri-vasculature, mesentery, bilateral iliac vessels, and pelvis; some lymph nodes were fused; the largest was located beside the left iliac vessels, measuring approximately 2.7*2.3cm, with increased FDG uptake (SUVmax=11.0).
A small amount of pelvic effusion.
Extensive thickening of the soft tissue in the left ethmoid sinus and bilateral nasal cavities with increased FDG uptake (SUVmax = 9.8), involving both inferior turbinates.
Thickening of the bilateral maxillary sinus mucosa, with no abnormalities in FDG metabolism.
Multiple areas of increased FDG uptake in the right metacarpals, bilateral ulna, radius, bilateral humerus, sacrum, coccyx, right acetabulum, bilateral femur, bilateral tibia, fibula, and bilateral foot bones (SUVmax = 16.6), with partial bone destruction; multiple subcutaneous soft tissue nodules of varying sizes throughout the body, the largest being approximately 2.6*1.8cm in the left buttock, with increased FDG uptake (SUVmax = 8.7).
The brain morphology and structure are normal, with punctate slightly low-density shadows in the deep brain regions; no abnormalities in FDG metabolism.
The ventricles, sulci, fissures, and cisterns are widened, but local density and FDG uptake are normal.
Midline structure is not shifted.
The eyeballs are symmetrical, but the lenses are poorly visualized bilaterally.
The nasopharyngeal wall is not thickened, and FDG uptake is normal.
The pharyngeal recesses are symmetrical, the Eustachian tube openings are not narrowed, the infratemporal and pterygopalatine fossae are normal, and the parapharyngeal spaces are clear bilaterally with normal FDG uptake.
The palatine tonsils show physiological uptake bilaterally.
No abnormal density shadows are seen in the parotid and submandibular glands bilaterally.
The laryngopharynx is normal in shape and structure.
The thyroid gland is normal in shape and size, with slightly uneven density, but FDG uptake is normal.
Increased translucency in both lungs, with multiple air-filled cavities.
A thin cystic cavity, approximately 7.7 cm in long diameter, is seen in the right upper lobe.
Bronchiectasis with a honeycomb-like appearance is present in the left lower lobe, surrounded by consolidation and increased FDG uptake (SUVmax = 3.6).
Calcification is present in the posterior segment of the right lower lobe, with scattered linear lesions in both lungs; FDG uptake is normal.
Nodular thickening of the left pleura is accompanied by increased FDG uptake (SUVmax = 5.2).
Cardiac enlargement is observed, with pericardial thickening and a small amount of effusion; cardiac chamber density is lower than myocardial density.
Calcification is present in some arterial walls (including coronary arteries).
No esophageal dilatation, significant wall thickening, or mass is observed; FDG uptake is not increased.
The liver appears normal in shape and size, with smooth borders and no widening of the hepatic fissure.
A slightly low-density lesion, approximately 1.5 cm in diameter, is present in the left medial lobe of the liver, with increased FDG uptake (SUVmax = 9.5).
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder appears normal in shape and size, with multiple dense shadows within it, the largest approximately 1.0 cm in long diameter.
The gallbladder wall is thickened, but local FDG uptake is normal.
The pancreas appears normal in shape, with no significant abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is normal.
The spleen appears normal in shape, size, density, and FDG uptake.
Both kidneys appear normal in shape and size.
A cystic lesion, approximately 2.2 cm in long diameter, is present in the left kidney, with absent FDG uptake.
Both renal pelvises and calyces are dilated with fluid accumulation, but FDG uptake is normal.
Nodular and patchy soft tissue density shadows were seen in both adrenal regions, the left side being larger, measuring approximately 4.7*2.3cm, with increased FDG uptake (SUVmax = 11.1).
Stomach distension was poor, with slight thickening of part of the gastric wall, and increased FDG uptake (SUVmax = 4.7).
Intestinal distension was unsatisfactory, with a considerable amount of residual contents in the intestinal lumen, exhibiting physiological uptake.
The prostate was enlarged, with a long diameter of approximately 5.0cm, containing patchy dense shadows; FDG uptake was not abnormally increased.
Bladder distension was poor, with no obvious positive stones.
Slight scoliosis was observed in the spine, with osteophyte formation at the margins of some vertebral bodies; L4/5 intervertebral disc bulge with pneumodegenerative changes.
The mediastinal blood pool SUVmax was 1.8, and the liver SUVmax was 2.6, used for the Deauville score.

Impression

1. a. Multiple lymphadenopathy throughout the body with increased FDG metabolism (see description for details). b. Extensive thickening of soft tissue in the left ethmoid sinus and bilateral nasal cavities with increased FDG metabolism; nodular thickening of the left pleura with increased FDG metabolism. c. Slightly low-density lesion in the left lobe of the liver with increased FDG metabolism; space-occupying lesion in the bilateral adrenal regions with increased FDG metabolism. d. Multiple areas of bone with increased FDG metabolism throughout the body, with partial bone destruction (see description for details); multiple subcutaneous soft tissue nodules with increased FDG metabolism throughout the body. All of the above suggest multisystemic lymphoma infiltration; follow-up examination after treatment is recommended.

2. a. Bronchiectasis with infection in the left lower lobe of the lung; follow-up CT scan after treatment is recommended. b. Emphysema in both lungs; bullae in the right upper lobe of the lung. Calcification in the lower lobe of the right lung, scattered post-inflammatory lesions in both lungs.? c. Thickening and adhesions of the left pleura. Enlarged cardiac silhouette, thickened pericardium with a small amount of effusion, anemic changes, calcification of some arterial walls (including coronary arteries).

3. Chronic cholecystitis, gallstones. Left renal cyst, bilateral renal pelvis and calyces dilation with effusion. Benign prostatic hyperplasia with calcification.

4. Chronic inflammatory changes in part of the gastric wall.

5. Slight scoliosis, degenerative changes in the spine, L4/5 intervertebral disc bulge with pneumoconiosis.

6. Senile brain, deep lacunar infarcts. Chronic inflammation of both 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.
