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: an irregular soft tissue mass with indistinct borders, heterogeneous internal density, and irregular calcifications in the left hippocampus, with increased FDG uptake (SUVmax = 54.3) and an uptake area of approximately 5.1*2.9cm.
Patchy low-density shadows were seen around the tumor.
The posterior horn of the left ventricle was indistinct.
No widening of the remaining ventricles, sulci, fissures, or cisterns was observed.
The midline was slightly deviated to the right.
The bilateral eyeballs showed normal morphology and contours, with clear retrobulbar structures.
The optic nerves were symmetrical, and FDG uptake was normal.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, with increased FDG uptake (SUVmax = 3.4).
The bilateral pharyngeal recesses were symmetrical, and there was no stenosis of the Eustachian tube openings.
The infratemporal fossa and pterygopalatine fossa structures were normal, and the bilateral parapharyngeal spaces were clear, with no abnormal FDG uptake.
The palatine tonsils are full and well-formed, with increased FDG uptake (SUVmax = 8.6).
The laryngopharynx is normal in shape and structure.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No significantly enlarged lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, or submental region, and FDG uptake is normal.
The chest is symmetrical, with clear lung markings.
A ground-glass nodule with a long diameter of approximately 0.6 cm is seen in the apical segment of the right upper lobe, with clear borders and normal FDG uptake.
The trachea is midline, and the trachea and segmental bronchi are patent.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions, and FDG uptake is normal.
The pleura is not thickened bilaterally, and there is no pleural effusion or pneumothorax.
The cardiac silhouette is normal.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or swollen, and FDG uptake is normal.
The breast tissue is full and dense bilaterally, with no abnormal density shadows, and FDG uptake is normal.
Small lymph nodes, approximately 0.4 cm in short diameter, were observed in both axillae; FDG uptake was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissures.
No significant abnormal density shadows were observed in the liver parenchyma; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall, no positive stones or obvious masses, and FDG uptake was normal.
The pancreas showed no abnormalities in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys showed no abnormalities in shape or size, with no significant abnormal density shadows in the renal parenchyma; FDG uptake was normal.
No widening was observed in the renal pelvis, calyces, or ureters bilaterally, and no positive stones were observed.
Both adrenal glands showed no abnormalities in shape or density; FDG uptake was normal.
Gastric distension was poor, but FDG uptake was not significantly abnormal.
Bowel preparation was poor, with no obvious masses in the intestinal wall, and FDG uptake was physiological.
The uterus was normal in shape, with no abnormal density shadows in the uterine body or cervix.
An intrauterine device was found in the uterine cavity, and FDG uptake in the endometrial area was increased (SUVmax = 3.7).
No abnormal density was seen in the bilateral adnexa, and FDG uptake was normal.
The bladder was poorly distended, with no positive stones or obvious masses.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region, and FDG uptake was normal.
No obvious fluid accumulation was seen in the abdominal or pelvic cavities.
The spinal alignment was normal, with L4/5 and L5/S1 intervertebral disc bulges.
Brown fat was visible in the bilateral neck and shoulder areas and on both sides of the spine.

Impression

1. A mass in the left hippocampus with increased FDG metabolism, suggestive of malignancy, accompanied by peritumoral edema and slight rightward midline deviation. Please combine with enhanced MRI for comprehensive assessment.

2. Ground-glass nodule in the apical segment of the right upper lobe, with normal FDG metabolism, suggestive of chronic inflammatory nodule or atypical adenomatous hyperplasia. Please combine with annual follow-up via HRCT.

3. Bilateral breast hyperplasia. Reactive hyperplasia of bilateral axillary lymph nodes.

4. Increased FDG metabolism in the endometrial area after intrauterine device insertion, likely a physiological change. Please combine with ultrasound follow-up.

5. L4/5 and L5/S1 intervertebral disc bulge.

6. Chronic inflammation of the nasopharynx and bilateral palatine tonsils is highly probable. Please combine with specialist examination.

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.
