Whole-body 18F-FDG PET/CT scan in a patient with Glioma 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: The brain morphology and structure were normal.
A ring-shaped high-density lesion, approximately 3.6*3.0cm in size, was seen in the right basal ganglia and corona radiata.
The lesion had clear borders and was low-density in the central part.
FDG uptake was reduced or absent.
Edema was seen in the surrounding brain parenchyma.
The adjacent right ventricle was compressed, and the midline structure was slightly deviated to the left.
A small nodular low-density lesion with clear borders was seen in the left parietal lobe, with no abnormal FDG uptake.
Both eyes were symmetrical, with no obvious abnormalities.
The maxillary sinus mucosa was thickened bilaterally, while the mucosa of the other paranasal sinuses was not thickened, and the sinus walls were intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, the Eustachian tube openings were not narrowed, the infratemporal fossa and pterygopalatine fossa structures were normal, and the bilateral parapharyngeal spaces were clear, with no abnormal FDG uptake.
Bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in bilateral 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; FDG uptake was normal.
No enlarged lymph nodes were seen in bilateral deep cervical spaces or submandibular regions.
Increased lung markings were observed bilaterally.
Multiple bronchiectasis with thickened walls and patchy shadows were seen in the right middle lobe and both lower lobes, with slightly increased FDG uptake (SUVmax = 2.9).
Scattered linear lesions were observed bilaterally; FDG uptake was normal.
No pleural thickening was observed bilaterally; there was no pleural effusion or pneumothorax bilaterally.
Small mediastinal lymph nodes were visible, the largest with a short diameter of approximately 0.9 cm; FDG uptake was normal.
The cardiac silhouette was normal.
Calcification of some arterial walls was observed (including the coronary arteries).
A cystic lesion was observed in the left anterior superior mediastinum, with clear borders, measuring approximately 4.3*2.0cm, with absent FDG uptake.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth liver margins and no widening of the hepatic fissure.
Multiple slightly low-density lesions were present within the liver, the largest located in the right posterior lobe, with clear borders, measuring approximately 4.4*3.5cm, with a CT value of approximately 38 HU, and background 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, no thickening of the gallbladder wall, and no abnormal local FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
Spleen morphology, size, density, and FDG uptake were normal.
A soft tissue density nodule adjacent to the spleen, approximately 0.7 cm in diameter, showed no abnormal FDG uptake.
Both kidneys were normal in shape and size.
A cystic lesion, approximately 1.0 cm in diameter, was observed at the upper pole of the right kidney.
Several other high-density lesions were also seen in the right kidney, the largest approximately 0.8 cm in diameter.
FDG metabolism was normal.
No widening of the renal pelvis, calyces, or ureters was observed, and FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no significant abnormalities.
Stomach distension was poor, with slight thickening of the antral wall and mildly increased FDG uptake (SUVmax = 3.1).
Intestinal distension was unsatisfactory, but intestinal uptake was physiological.
The prostate was normal in size and density, with no abnormally increased FDG uptake.
Bladder distension was poor, and no obvious positive stones were observed.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L3/4, L4/5, and L5/S1 intervertebral disc bulges.
Systemic bone marrow FDG metabolism was normal.

Impression

1. Space-occupying lesions in the right basal ganglia and corona radiata, with decreased or absent FDG uptake, suggestive of malignancy, with glioblastoma being the primary consideration.

2. Softening lesion in the left parietal lobe. Chronic inflammation of the bilateral maxillary sinuses.

3. a. Multiple bronchiectasis with infection in the right middle lobe and both lower lobes; follow-up CT scan after treatment is recommended. b. Scattered post-inflammatory lesions in both lungs. Reactive hyperplasia of mediastinal lymph nodes. Benign lesions in the anterior mediastinum; cysts are the primary consideration. Calcification of some arterial walls (including coronary arteries).

4. Multiple slightly low-density lesions in the liver, with background FDG uptake; hemangioma or cysts are the primary consideration; further enhanced MRI is recommended to rule out other possibilities. Accessory spleen. Right renal cyst (partially complex).

5. Chronic inflammatory changes in the gastric antrum; please follow up with endoscopy.

6. Degenerative changes in the spine, with L3/4, L4/5, and L5/S1 disc bulges.

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.
