Whole-body 18F-FDG PET/CT scan in a patient with Nasopharyngeal Cancer 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: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
Following treatment for nasopharyngeal carcinoma, no significant space-occupying lesion was observed in the nasopharynx, and FDG metabolism was normal.
The bone density of adjacent skull bones was uneven.
The bilateral infratemporal fossa and pterygopalatine fossa structures were normal, with no abnormalities in FDG uptake.
Multiple lymph nodes were observed in the bilateral deep cervical spaces, the left posterior cervical triangle, and the supraclavicular fossa.
The largest was located in the left posterior cervical triangle, measuring approximately 1.6*1.1cm, with slightly increased FDG metabolism (SUVmax = 1.6).
Thickening of the left maxillary sinus mucosa, sinus wall intact.
Bilateral palatine tonsils show physiological uptake.
Laryngopharyngeal morphology and structure are normal.
No abnormal density shadows are seen in bilateral parotid and submandibular glands.
Thyroid gland morphology and size are normal, density is uniform, FDG uptake is normal.
One pure ground-glass nodule is seen in the apical segment of the right upper lobe and the anterior segment of the left upper lobe, with relatively clear borders; the larger one has a long diameter of approximately 0.3 cm, FDG uptake is normal.
A solid nodule is seen in the posterior basal segment of the left lower lobe, with relatively clear borders, a long diameter of approximately 0.2 cm, FDG uptake is normal.
A few linear shadows are seen in the medial segment of the right middle lobe and the lingular segment of the left upper lobe, FDG uptake is normal.
No pleural thickening is seen bilaterally, no pleural effusion or pneumothorax is seen bilaterally.
No significantly enlarged lymph nodes are seen bilaterally in the hilum and mediastinum.
Cardiac silhouette is normal, cardiac chamber density is lower than myocardial density.
PICC line insertion.
Liver morphology and size: no obvious abnormalities observed; smooth liver margins; no widening of the hepatic fissure; slightly uneven density of liver parenchyma; intrahepatic vessels not clearly visualized; FDG uptake normal.
Main portal vein not significantly widened; no dilation of intrahepatic or extrahepatic bile ducts.
Gallbladder morphology and size: no abnormalities observed; gallbladder wall not thickened; local FDG uptake normal.
Pancreas morphology normal; no obvious abnormal density shadows observed in the parenchyma; no widening of the main pancreatic duct; FDG uptake normal.
Spleen morphology, size, density, and FDG uptake normal.
Kidneys morphology and size normal; no obvious abnormal density shadows observed in the parenchyma; no widening of the renal pelvis, calyces, or ureters; FDG uptake normal.
Bilateral adrenal gland imaging normal.
The esophagus was not dilated, and the esophageal wall showed no obvious thickening or mass; FDG uptake was not increased.
The stomach was poorly filled, but the gastric wall showed no obvious thickening; FDG uptake was not significantly abnormal.
The intestines were poorly filled, but the intestinal wall showed no obvious thickening or mass; FDG uptake was physiological.
The prostate was enlarged, with a transverse diameter of approximately 5.3 cm, and punctate calcifications were observed within it; FDG uptake was not abnormally increased.
The bladder was generally full, and no obvious positive stones were observed.
No enlarged lymph nodes were observed in the abdomen, pelvis, or retroperitoneal region; FDG metabolism was not abnormal.
No significant fluid accumulation was observed in the abdomen or pelvic cavity.
Multiple lesions were found in the right scapula, left clavicle, sternum, multiple vertebrae and appendages of the spine, bones of the pelvis, and the upper segment of the left femur, with the most significant damage located in the left ischium and pubis.
FDG uptake was increased, SUVmax=9.2, with an uptake range of approximately 3.3*1.8*4.6cm.
The T11 and L2 vertebrae were flattened.
Scoliosis and cervical recurvature were also observed; patchy FDG uptake was also present in the right shoulder area, SUVmax=3.7.

Impression

1. a. No obvious space-occupying lesions were observed in the nasopharynx, and FDG metabolism was normal, suggesting that tumor activity was largely suppressed after treatment. b. Bilateral cervical lymph nodes showed a significant reduction in size compared to before, with most disappearing, and FDG metabolism slightly increased, suggesting that tumor activity was largely suppressed after treatment. c. Multiple bone metastases throughout the body (see description for details) showed a reduction in lesion size compared to before, and decreased FDG metabolism, suggesting that most tumor activity was suppressed, with some tumors still showing activity. Pathological fractures of the T11 and L2 vertebral bodies were observed. The original right erector spinae muscle lesion was not visualized.

2. a. Pure ground-glass nodules were found in the apical segment of the right upper lobe and the anterior segment of the left upper lobe, with no abnormal FDG uptake, similar to before, suggesting atypical adenomatous hyperplasia or chronic inflammatory nodules. Annual HRCT follow-up is recommended.? b. Chronic inflammatory micronodules (solid) in the posterior basal segment of the left lower lobe; a few fibrotic foci in the medial segment of the right middle lobe and the lingular segment of the left upper lobe. Anemia changes, PICC line inserted.

3. Benign prostatic hyperplasia with calcification.

4. Scoliosis with cervical recurvature. Right shoulder periarthritis.

5. No obvious abnormalities seen on cranial imaging. Left maxillary sinusitis.

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.
