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: Normal brain morphology and structure; a mass with heterogeneous density was seen in the left basal ganglia, compressing the lateral ventricles and causing midline shift, measuring approximately 3.4*3.6cm, with increased FDG metabolism (SUVmax = 8.3).
Widening of the sulci, fissures, and cisterns was observed, and the cavity of septum pellucidum was formed.
Both eyes were symmetrical and showed no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, and there was no stenosis of the Eustachian tube openings.
The infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
Both palatine tonsils showed physiological uptake.
The laryngopharynx was normal in morphology and structure.
Small soft tissue nodules with increased FDG uptake were observed in both parotid glands, the largest measuring approximately 0.3*0.8cm (SUVmax = 4.7).
No abnormal density shadows were seen in the bilateral submandibular glands.
The thyroid gland was normal in shape and size, with slightly heterogeneous density, and FDG uptake was normal.
Multiple small lymph nodes were found in the bilateral deep cervical spaces and axillae, with increased FDG metabolism (SUVmax = 5.6).
A ground-glass nodule with clear borders and a long diameter of approximately 0.4 cm was seen in the lower lingular segment of the left upper lobe, and a small solid nodule with clear borders and a long diameter of approximately 0.3 cm was also seen in the lower lingular segment of the left upper lobe; FDG uptake was normal in both cases.
There was slight thickening of the pleura in parts of both sides, but no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
Some arterial walls showed calcification.
The cardiac silhouette was normal.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was normal.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissure.
A low-density lesion with a long diameter of approximately 0.5 cm was seen in the left lobe of the liver; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was normal 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 was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size; a dense shadow was observed in the left kidney, with a long diameter of approximately 0.8 cm, and a punctate fat density foci were also seen within the parenchyma; FDG uptake was normal.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was poorly distended, with no significant thickening of the stomach wall and no obvious abnormal FDG uptake.
The intestines were poorly distended, with no significant thickening or mass in the intestinal wall; FDG uptake was physiological.
Increased FDG metabolism in the anal canal (SUVmax = 8.9).
The prostate is of normal size, with calcifications observed; FDG uptake is not abnormally increased.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulging.
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. a. A mass in the left basal ganglia region with increased FDG metabolism, suggesting a high probability of a primary malignant tumor, such as glioblastoma. Further examination with contrast-enhanced MRI is recommended. b. Senile brain changes. Cavity septum pellucidum formation.

2. a. Ground-glass nodule in the lower lingular segment of the left upper lobe, with no increased FDG metabolism, suggesting a chronic inflammatory nodule or atypical adenomatous hyperplasia. Annual HRCT follow-up is recommended. Chronic inflammatory micronodule (solid) in the lower lingular segment of the left upper lobe. b. Slight thickening of the pleura on both sides. Reactive hyperplasia of the lymph nodes in the deep cervical space and axilla on both sides.

3. Calcification of the arterial walls on both sides.

4. Small cyst in the left lobe of the liver. Localized calcium salt deposition or contrast agent residue in the left kidney. Small vascular leiomyolipomas of the left kidney. Calcification of the prostate. Possible hemorrhoids.

5. Osteophyte formation in the vertebrae on both sides. L4/5 and L5/S1 intervertebral disc bulge.

6. Reactive hyperplasia of small lymph nodes in the parotid glands on both sides.

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.
