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: Brain morphology and structure were normal, with punctate low-density lesions in the deep cerebral regions bilaterally; FDG uptake was not significantly abnormal.
Some ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
Following comprehensive treatment of the nasopharyngeal lesion: No significant thickening of the soft tissue on the lateral and posterior walls of the nasopharynx was observed; the pharyngeal recesses were symmetrical bilaterally, and FDG uptake was not abnormal.
The left maxillary sinus mucosa showed thickening with cystic, slightly low-density lesions; FDG uptake was not abnormal, and the sinus walls were intact.
The palatine tonsils were symmetrical bilaterally, and FDG uptake was physiological.
The laryngopharynx morphology and structure were normal.
The parotid and submandibular glands bilaterally had normal morphology and density, and FDG uptake was physiological.
The thyroid gland is normal in shape and size, but its density is somewhat uneven, and FDG uptake is also uneven, with SUVmax=2.5.
Multiple small lymph nodes with a short diameter of approximately 0.2-0.5cm are visible in the bilateral deep cervical spaces and submandibular region; FDG uptake is normal.
Solid micronodules of 0.2-0.4cm are seen in the right upper lobe and the posterior segment of the left lower lobe; FDG uptake is normal.
Linear and patchy slightly high-density lesions are seen in both lower lobes of the lungs; FDG uptake is normal.
The posterior pleura is slightly thickened bilaterally; there is no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or swollen; FDG uptake is not increased.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
Plain CT scan revealed patchy calcifications in the right lobe of the liver, with no abnormal FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities 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 showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormal FDG uptake.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension is poor; no significant thickening is observed in parts of the stomach and duodenal walls.
FDG uptake is increased, SUVmax = 2.7.
Intestinal distension is poor; high-density diverticula are seen in the sigmoid colon wall.
FDG uptake shows a continuous increase, SUVmax = 9.4 (considered physiological uptake).
Prostate size is normal, density is uniform, and FDG uptake is not abnormally increased.
Bladder distension is poor; no obvious positive stones are seen.
Punctate dense shadows are seen in the tunica vaginalis of both testes.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation is seen in the abdominal or pelvic cavities.
Spinal alignment is normal; some vertebral body margins show osteophyte formation, and L4/5 intervertebral disc bulge.
Calcifications are seen in the soft tissue beside the greater trochanter of the left femur; FDG uptake is increased, SUVmax = 2.8.
Reduced FDG uptake in the cervical spine and part of the thoracic spine.

Impression

1. a. After comprehensive treatment of "nasopharyngeal lesion": No significant thickening of the nasopharyngeal wall was observed, and FDG metabolism was not increased, suggesting that tumor activity was basically suppressed after treatment. b. Bilateral deep cervical spaces and submandibular lymph nodes showed no abnormal FDG uptake, suggesting reactive hyperplasia is highly likely; follow-up is recommended. c. Changes after cervical and thoracic spine radiotherapy.

2. Thyroid gland density and FDG uptake are uneven; please follow up with ultrasound.

3. Chronic inflammatory micronodules (solid) in the right upper lobe and posterior segment of the left lower lobe; a few chronic inflammations and remnants in both lower lobes; slight pleural thickening in some areas. Similar to the previous findings.

4. Liver calcifications. Bilateral testicular tunica vaginalis calcifications.

5. Chronic inflammatory or physiological uptake of the stomach and duodenum; please follow up with gastroscopy. Sigmoid colon diverticulum.

6. Degenerative changes in the spine, L4/5 disc bulge. Chronic inflammation with calcifications in the soft tissues surrounding the greater trochanter of the left femur.

7. Age-related brain, deep lacunar infarcts. Chronic inflammation with submucosal cysts in the left maxillary sinus.

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.
