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, a whole-body PET/CT scan was performed.
The whole-body images showed: Normal brain morphology and structure, with a few punctate low-density shadows in the deep brain regions; no significant abnormalities were observed in FDG uptake.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
A slightly high-density nodule, approximately 2.1 cm in diameter, was seen in the left cerebellum, with absent FDG metabolism.
A slightly high-density nodule, approximately 1.0 cm in diameter, was seen in the right cerebellum, with increased FDG metabolism (SUVmax = 9.8).
Both eyeballs were symmetrical, with no significant abnormalities.
A small amount of mucosal thickening was observed in the right maxillary sinus and left sphenoid sinus, with intact sinus walls.
No thickening was observed in the nasopharyngeal wall; no abnormalities were observed in FDG uptake.
The pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear, with no abnormalities in FDG uptake.
The palatine tonsils showed physiological uptake.
The morphology and structure of the laryngopharynx were normal.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with slightly heterogeneous density; FDG uptake was normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
A cystic cavity was seen in the posterior segment of the left lower lobe, surrounded by mixed ground-glass opacities, measuring approximately 1.3*0.9cm.
Multiple pure ground-glass nodules were seen in both lungs, with clear borders, and a long diameter of approximately 0.3-0.6cm.
Multiple small solid nodules were seen in both lungs, with clear borders, and a long diameter of approximately 0.2-0.5cm; FDG uptake was normal in all cases.
Scattered linear shadows and cystic lucent shadows were seen in both lungs.
A bulla was formed in the right upper lobe.
Partial bronchiectasis was seen in the right middle lobe, with nodular high-density shadows visible inside; FDG uptake was normal.
No pleural thickening was seen bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Multiple irregular soft tissue masses, approximately 5.8*5.0cm in size, were observed in the pretracheal space and below the carina, with increased FDG metabolism (SUVmax = 8.0).
A nodule, approximately 1.0cm in long diameter, was observed in the right cardiophrenic angle, with increased FDG metabolism (SUVmax = 4.1).
Calcification of some arterial walls (including coronary arteries) was present.
Pericardial effusion was observed.
The esophagus showed no dilation, no significant thickening or mass in the wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and no abnormal FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall.
No nodular slightly high-density shadows were observed within the gallbladder, and no abnormal local FDG uptake was observed.
A slightly low-density mass measuring approximately 2.6*1.5cm was observed in the tail of the pancreas, with increased FDG metabolism (SUVmax = 6.5).
The spleen showed no abnormalities in morphology, size, density, or FDG uptake.
Accessory splenic nodules were visible.
Both kidneys were normal in shape and size, with no obvious abnormal density in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
The stomach was poorly distended, with no obvious thickening of the gastric wall and no obvious abnormalities in FDG uptake.
The intestines were poorly distended, with no obvious thickening or mass in the intestinal wall.
Linear high-density shadows were seen in the sigmoid colon and rectum, with physiological FDG uptake.
The prostate was of normal size and uniform density, with no abnormally increased FDG uptake.
The bladder was generally full, with no obvious positive stones.
A hydrocele was observed in the left testis.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region.
No significant effusion was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 intervertebral disc bulge.
No abnormal FDG metabolism was observed in the entire skeleton.

Impression

1. a. Mediastinal soft tissue mass with elevated FDG metabolism, suggestive of malignancy, possible metastasis, mediastinal lung cancer to be ruled out. Right cardiophrenic angle nodule with elevated FDG metabolism, suggestive of metastasis. b. Cerebellar mass, one on the right side with elevated FDG metabolism, suggestive of metastasis, please combine with enhanced MRI for comprehensive analysis.

2. Slightly low-density mass in the tail of the pancreas with elevated FDG metabolism, suggestive of malignancy, pancreatic cancer is highly likely, metastasis to be ruled out, please combine clinical and enhanced MRI for comprehensive analysis.

3. a. Cystic cavity in the posterior segment of the left lower lobe with surrounding mixed ground-glass opacity, low FDG metabolism, suggestive of chronic inflammation, cystic lung cancer to be ruled out, close observation recommended. b. Multiple pure ground-glass nodules in both lungs, low FDG metabolism, suggestive of atypical adenomatous hyperplasia or chronic inflammatory nodules. Multiple solid nodules in both lungs, low FDG metabolism, high probability of chronic inflammatory nodules. c. Bronchiectasis in the right middle lobe with mucus plug formation. Scattered chronic inflammation and sequelae in both lungs. Emphysema in both lungs, bullae in the right upper lobe.

4. Calcification of some arterial walls (including coronary arteries). Pericardial effusion.

5. Gallstones. Accessory spleen. Hydrocele of the left testis. Schistosomiasis intestinal infection.

6. A few ischemic foci in the deep brain. Age-related brain changes. A few chronic inflammations of the right maxillary sinus and left sphenoid sinus.

7. Osteophyte formation in some vertebrae. L4/5 disc bulge.

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.
