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 cystic low-density lesion with internal septa was seen in the left temporal lobe, measuring approximately 2.3*1.2cm, with FDG metabolism absent.
A cystic low-density lesion measuring approximately 3.3*1.9cm was seen in the left temporal pole, also with FDG metabolism absent.
No widening was observed in the ventricles, sulci, fissures, or cisterns.
The ventricles were symmetrical, and there was no midline shift.
Both eyes 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 fossa and pterygopalatine fossa structures were normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
The 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 was normal in shape and size, with low-density nodules in both lobes; the larger nodule was located in the right lobe, approximately 0.7 cm in diameter.
FDG uptake was normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
The lung markings were clear bilaterally, with no obvious abnormal density shadows, and FDG uptake was normal.
No pleural thickening was seen bilaterally, and there was no pleural effusion or pneumothorax.
No obvious enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The density of the cardiac chambers was lower than that of the myocardium.
No esophageal dilation was seen, and no obvious thickening or mass was seen in the esophageal wall; FDG uptake was not increased.
The bilateral mammary glands were dense, and FDG metabolism was normal.
The liver appears normal in shape and size, with smooth borders.
Multiple low-density lesions are observed within the liver parenchyma, the largest measuring approximately 3.1 cm in long diameter, with clear borders and absent FDG uptake.
Patchy low-density shadows are seen along the course of the hepatic Green's sheath, with decreased FDG metabolism.
Slightly enlarged lymph nodes are present at the porta hepatis, approximately 0.6 cm in short diameter, with slightly increased FDG metabolism (SUVmax = 3.7).
The gallbladder structure is not clearly visualized, and local FDG uptake is normal.
The pancreas appears normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is normal.
The spleen appears full, with no abnormal density or FDG uptake.
Both kidneys appear normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension was poor, but the gastric wall showed no obvious thickening, and FDG uptake was normal.
Intestinal distension was poor, but the intestinal wall showed no obvious thickening or mass, and FDG uptake was physiological.
Uterus shape was irregular, but FDG uptake was not abnormally increased.
No abnormal FDG metabolism was observed in the bilateral adnexa.
The bladder wall showed no abnormal thickening, and no obvious positive stones were observed.
No enlarged lymph nodes were observed in the abdominopelvic region or retroperitoneal region.
No obvious fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes.
Systemic bone FDG metabolism was normal.

Impression

1. a. Cystic mass with septa in the left temporal lobe, FDG metabolism absent; combined with contrast-enhanced MRI from another hospital, glioma is suspected. b. Left temporal pole arachnoid cyst.

2. Combined with MRI from another hospital, hepatic Grinson's sheath edema is suspected. Multiple hepatic cysts. Reactive hyperplasia of hilar lymph nodes. Splenomegaly.

3. Anemia.

4. Bilateral breast hyperplasia.

5. Uterine fibroids.

6. Partial vertebral osteophyte formation.

7. Low-density thyroid nodule, FDG uptake normal, nodular goiter is suspected; follow-up ultrasound is recommended.

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.
