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 slightly high-density ring-shaped lesion measuring approximately 3.8*2.6cm was observed in the left temporal lobe, with increased FDG metabolism (SUVmax = 7.5), surrounded by a large area of low-density lesion with absent FDG metabolism.
No widening of the ventricles, sulci, fissures, or cisterns was observed.
Mild compression of the left ventricle and slight rightward deviation of the midline structures were observed.
Both eyeballs 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 bilateral 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.
Bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were observed 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 are seen in the bilateral deep cervical spaces or submandibular region.
Scattered solid nodules with clear borders, approximately 0.3-0.5 cm in long diameter, are present in both lungs.
Calcification foci are present in the left upper lobe and right lower lobe; FDG uptake is normal in both lungs.
No pleural thickening is seen bilaterally; there is no pleural effusion or pneumothorax.
Several small lymph nodes are seen in the bilateral hilar and mediastinal regions; FDG metabolism is increased, SUVmax = 3.8.
The cardiac silhouette is normal.
Some arterial walls are calcified.
The esophagus is not dilated; the wall is not significantly thickened or swollen; FDG uptake is normal.
Localized glandular density is present in both breasts; FDG metabolism is normal.
The liver is normal in shape and size; the liver margins are smooth; the hepatic fissure is not widened; no obvious abnormal density shadows are seen in the liver parenchyma on plain CT scan; FDG uptake is 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 cystic lesion was seen in the left kidney, approximately 0.5 cm in long diameter; no widening of the renal pelvis, calyces, or ureter was observed, and no obvious abnormal FDG uptake was observed.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
The stomach was poorly distended, with slight thickening of the walls of the cardia, part of the gastric body, and antrum, and a slightly increased FDG uptake (SUVmax = 3.2).
The intestines were poorly distended, with increased local FDG metabolism in the ascending colon, descending colon, and sigmoid colon (SUVmax = 6.5).
The uterus was normal in shape, with no abnormal density shadows and no abnormally increased FDG uptake.
No abnormal FDG metabolism was observed in the bilateral adnexa.
The bladder was generally full, and no obvious positive stones were seen within it.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
Increased bone density was observed in the T11 vertebral body, with slightly increased FDG uptake (SUVmax = 3.1).
The spinal alignment was normal, with some vertebral body marginal osteophytes.
Nuchal ligament calcification was present.

Impression

1. a. A mass in the left temporal lobe with increased FDG metabolism and surrounding extensive edema, suggestive of malignancy, with glioblastoma being more likely than metastasis. b. Increased bone density in the T11 vertebral body, accompanied by increased FDG uptake, metastasis to be ruled out; close observation is recommended.

2. Scattered chronic inflammatory nodules in both lungs; please follow up with CT to rule out other possibilities. Calcifications in the left upper lobe and right lower lobe. Reactive hyperplasia of bilateral hilar and mediastinal lymph nodes. Calcification of some arterial walls.

3. Bilateral breast hyperplasia.

4. Chronic gastritis; some physiological or inflammatory uptake of the intestines; please follow up with endoscopy.

5. Left renal cyst.

6. Partial vertebral osteophyte formation. Nuchal ligament calcification.

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.
