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, a whole-body PET/CT scan was performed.
The whole-body scan showed:Slightly high-density soft tissue shadows with indistinct borders were seen in the left pons, midbrain, and thalamus, with increased FDG metabolism (SUVmax = 11.5).
No widening was observed in the ventricles, sulci, fissures, or cisterns.
The ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no obvious abnormalities.
No thickening was observed in the paranasal sinus mucosa, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally 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 the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
A small air-filled cystic cavity was seen in the right lung apex.
Punctate calcifications were seen in the left upper lobe.
Several solid micronodules were observed in both lungs, approximately 0.2-0.3 cm in long diameter, with clear borders; FDG metabolism was normal.
A few punctate and linear lesions were also seen in both lungs; FDG metabolism was normal.
No pleural thickening was observed bilaterally; there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
No esophageal dilation was observed; no significant thickening or mass was seen in the esophageal wall; FDG uptake was normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was 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 showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormal FDG uptake.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension is poor, with slight thickening of the walls in parts of the gastric body and antrum.
FDG uptake is slightly increased, SUVmax=2.3.
Intestinal distension is unsatisfactory, with increased FDG metabolism in parts of the intestine, SUVmax=4.6.
A metallic suture shadow is seen in the lower rectum, but FDG metabolism is normal.
The prostate is normal in shape and size, with uniform density, and no abnormal FDG metabolism is observed.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with a small amount of osteophyte formation at the edges of some vertebral bodies.
The left groin is enlarged, with fat density shadows seen within, but FDG metabolism is normal.
Systemic bone marrow FDG metabolism is normal.
Increased FDG metabolism was observed in the right longus capitis and right psoas major muscles, with SUVmax = 5.6.

Impression

1. A mass in the left pons, midbrain, and thalamus, with increased FDG uptake, strongly suggestive of a neoplastic lesion, possibly a glioma or germ cell tumor; lymphoma is a possibility. Please combine this with functional MRI for comprehensive analysis.

2. Several small, solid, chronic inflammatory nodules in both lungs. A few chronic inflammations and old lesions in both lungs. Para-septal emphysema in the right lung. Calcification in the upper lobe of the left lung.

3. Slight thickening of the walls of part of the gastric body and antrum, with mildly increased FDG uptake, suggestive of chronic gastritis; increased FDG uptake in part of the intestinal tract, suggestive of inflammatory or physiological uptake. Follow-up with gastroscopy and colonoscopy is recommended. Postoperative changes in the lower rectum.

4. Left inguinal hernia.

5. Mild vertebral osteophyte formation. Tonic uptake of the right longus capitis and right psoas major muscles.

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.
