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.
There was no widening of the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no obvious abnormalities.
Irregular thickening and bulging of the posterior and bilateral walls of the nasopharynx, protruding into the posterior nasal cavity and involving the nasal septum, was observed, with increased FDG metabolism (SUVmax = 14.2) and an uptake area of approximately 2.5 1.5 cm.
Decreased bone density was observed at the base of the occipital bone, with increased density in the right mastoid process.
A slightly enlarged lymph node was seen in the left deep cervical space, with a short diameter of approximately 0.7 cm, and increased FDG metabolism (SUVmax = 5.1).
Thickening of the mucosa in both maxillary sinuses, ethmoid sinuses, and sphenoid sinuses, with intact sinus walls.
Bilateral palatine tonsils show physiological uptake.
No abnormal density shadows are seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx are normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
A few speckled and linear lesions are seen in both lungs; FDG metabolism is normal.
No thickening of the pleura is seen 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 ascending aorta is slightly widened.
No dilation of the esophagus is seen; no significant thickening or mass is seen in the esophageal wall; FDG uptake is not increased.
Both breasts are normal; FDG metabolism is normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
A punctate calcification was observed in the left lateral lobe of the liver, and a cystic low-density lesion with a long diameter of approximately 0.6 cm was also seen in the left lobe.
FDG uptake was normal.
The main portal vein showed no obvious widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
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 abnormalities in 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 abnormalities in FDG uptake.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension is poor, with no obvious thickening of the stomach wall and no obvious abnormalities in FDG uptake.
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
Uterus shape is normal, with no abnormal FDG metabolism.
Metal clip shadows are seen in both adnexa.
Bladder distension is normal, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious fluid accumulation is seen in the abdominal or pelvic cavities.
Spinal alignment is normal, with slight osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulges.
A 4.6*3.4cm fat density lesion is seen in the muscle of the right upper humerus; FDG uptake is normal.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Nasopharyngeal mass with increased FDG metabolism, consistent with nasopharyngeal carcinoma, involving the posterior nasal cavity, nasal septum, and adjacent skull base bone. b. High probability of left deep cervical lymph node metastasis. Right mastoiditis.

2. Minor chronic inflammation and old lesions in both lungs. Slightly widened ascending aorta.

3. Liver calcification. Small cyst in the left lobe of the liver.

4. Post-tubal ligation changes.

5. Mild degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge. Intramuscular lipoma in the upper right humerus.

6. No abnormalities seen on cranial scintigraphy. Chronic inflammation of bilateral maxillary sinuses, bilateral ethmoid sinuses, and sphenoid sinuses.

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.
