Whole-body 18F-FDG PET/CT scan in a patient with Lung 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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed:Normal brain morphology and structure; a crescent-shaped low-density shadow was seen under the left parietal cranial plate, with absent FDG uptake.
Punctate low-density shadows were seen in the deep cerebral regions bilaterally, with no significant abnormalities in FDG uptake.
Widening of some ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal, and there was no midline shift.
Normal morphology and contour of both eyeballs; clear retrobulbar structures; symmetrical optic nerves bilaterally; and no significant abnormalities in FDG uptake.
Thickening of the mucosa of both ethmoid sinuses and the right maxillary sinus, with intact sinus walls.
No thickening of the nasopharyngeal wall was observed; no stenosis of the bilateral pharyngeal recesses and Eustachian tube openings; normal structures of the bilateral infratemporal fossa and pterygopalatine fossa; clear bilateral parapharyngeal spaces; and no abnormalities in FDG uptake.
FDG uptake in the oropharynx and laryngopharynx was physiological.
No abnormal contrast was observed in the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
Small lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake is normal.
The interlobular septa of the right lung are thickened, showing a reticular pattern, with scattered solid nodules and soft tissue masses.
The largest is located in the right middle lobe, measuring approximately 6.9*5.0*3.7cm, with indistinct borders, lobulated edges, and spiculated margins.
Adjacent pleura is stretched, and a local bronchus is truncated; FDG uptake is increased (SUVmax = 7.5).
The right pleura is thickened, with increased FDG uptake (SUVmax = 4.5).
A small amount of effusion is seen in the right pleural cavity, and a drainage tube is present.
FDG uptake at the puncture site is increased (SUVmax = 8.2).
Multiple lymph nodes were observed in the right hilum, right internal mammary chain, and right anterior diaphragmatic group, the largest measuring approximately 0.7 cm in short diameter, with increased FDG uptake (SUVmax = 4.5).
Scattered solid nodules and patchy lesions were observed in the left lung, the largest located in the apical-posterior segment of the upper lobe with a long diameter of approximately 0.8 cm, with no abnormal FDG uptake.
A few small patchy hazy shadows were observed in both lungs.
The cardiac silhouette was normal, and myocardial FDG uptake was normal.
No significant thickening or mass was observed in the esophageal wall, and FDG uptake was not increased.
The liver morphology and size were normal, with smooth liver margins and no widening of the hepatic fissure.
A slightly low-density nodule with a long diameter of approximately 2.0 cm was observed in the upper segment of the right posterior lobe of the liver, with clear borders and background FDG uptake.
A cystic lesion with a long diameter of approximately 3.8 cm was observed in the left lobe of the liver, with absent FDG uptake.
No significant widening of the main portal vein was observed, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder appears normal in shape and size, with no thickening of the gallbladder wall, no positive stones or obvious masses, and no abnormal FDG uptake.
The pancreas appears normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen appears normal in shape and size, with no abnormal density or FDG uptake.
Both kidneys appear normal in shape and size, with cystic lesions in both kidneys, the largest being approximately 2.4 cm in the long diameter of the right kidney, and FDG uptake is absent.
The renal pelvis, calyces, and ureters appear normal, with no positive stones.
The adrenal glands appear normal in shape and density, with no abnormal FDG uptake.
The stomach is poorly filled, with increased FDG uptake in some parts of the stomach wall; SUVmax = 2.6.
Bowel preparation was poor; no obvious masses were observed in the intestinal wall, and FDG uptake was physiological.
The prostate was enlarged, with unevenly increased FDG uptake in the parenchyma (SUVmax = 2.7).
The bladder was adequately full, and no obvious positive stones were observed.
Multiple lymph nodes were observed in the bilateral pelvic walls and groin, the largest with a short diameter of approximately 1.4 cm; some showed increased FDG uptake (SUVmax = 2.5).
No significant fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment was normal, with some vertebral body margin osteophytes, L3/4 disc bulging, and L4/5 disc herniation.
A nodular dense shadow was observed on the left side of the sacrum, but FDG uptake was normal.

Impression

1. a. Scattered solid nodules and soft tissue masses in the right lung, with increased FDG metabolism, suggestive of malignancy. Right lung cancer with intrapulmonary metastasis is the primary consideration, with right lung cancer lymphangitis being highly probable. Please confirm the diagnosis with pathological examination. b. Metastasis to the right hilar, right internal mammary chain, and right anterior diaphragmatic lymph nodes is the primary consideration. c. Right pleural metastasis is the primary consideration, with right pleural effusion. Increased FDG metabolism at the right chest wall drainage tube puncture site suggests inflammatory changes; tumor infiltration needs to be ruled out. Please follow up. d. Chronic inflammatory nodules and plaque-like foci in the left lung, scattered chronic inflammation in both lungs.

2. Benign prostatic hyperplasia, with unevenly increased FDG metabolism in the parenchyma. Please rule out space-occupying lesions with PSA and enhanced MRI. Reactive hyperplasia of bilateral pelvic wall and inguinal lymph nodes. Please follow up to rule out other possibilities.

3. Hemangioma in the upper right posterior lobe of the liver is the primary consideration; enhanced MRI analysis is recommended. Liver cysts. Bilateral renal cysts.

4. Increased FDG metabolism in part of the gastric wall, suggestive of physiological uptake or chronic inflammation; endoscopic follow-up is recommended.

5. Spinal degenerative changes. L3/4 disc bulge, L4/5 disc herniation. Left sacral islet.

6. Small amount of subdural effusion in the left parietal region, bilateral deep lacunar infarcts, age-related brain changes. Chronic inflammation of the bilateral ethmoid sinuses and right maxillary sinus.

7. Reactive hyperplasia of bilateral cervical lymph nodes.

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.
