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 eyes were symmetrical, with no significant abnormalities.
Thickening of the mucosa was observed in the right ethmoid sinus and right maxillary sinus; a cystic shadow with a diameter of approximately 0.5 cm was seen in the right maxillary sinus.
No thickening of the mucosa was observed in the other paranasal sinuses, and the sinus walls were intact.
The nasal septum was not deviated, and no significant thickening of the nasal mucosa was observed; FDG uptake was normal.
Extensive and irregular thickening of the soft tissue on the posterior and lateral walls of the nasopharynx, with increased FDG uptake (SUVmax = 14.1), covering an area of approximately 4.0cm x 3.3cm.
The surface of the increased uptake is irregular and the borders are indistinct.
The right pharyngeal recess is shallow and absent, invading the right parapharyngeal space and both posterior nasal openings, with destruction of the adjacent skull base bone.
Enlarged lymph nodes in the right retropharyngeal space, with a short diameter of 1.9cm, show increased FDG uptake (SUVmax = 8.3).
Bilateral deep cervical lymph nodes are visible, the largest with a short diameter of approximately 0.7cm, showing slightly increased FDG uptake (SUVmax = 1.7).
The morphology and structure of the laryngopharynx are normal, and the parapharyngeal space is clear.
The size, shape, and density of the bilateral submandibular and parotid glands are normal, with physiological FDG uptake.
Patchy increased FDG uptake is observed in the glottic region (SUVmax = 13.7).
A fluid density shadow is seen within the mastoid process of the right middle ear.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
Lung markings are clear bilaterally; a few patchy areas of increased density are observed in the lower lobe of the left lung; FDG uptake is normal.
No pleural thickening is observed bilaterally; no pleural effusion or pneumothorax is present bilaterally.
No significantly enlarged lymph nodes are observed bilaterally in the hilum or mediastinum.
Cardiac silhouette is normal.
A few soft tissue density shadows are observed in the anterior mediastinum; FDG metabolism is normal.
Breast tissue is dense bilaterally; no abnormal density shadows are observed; FDG metabolism is normal.
Esophageal dilatation is not observed; no significant thickening or mass is observed in the esophageal wall; FDG uptake is normal.
Liver shape and size are normal; liver margins are smooth; the hepatic fissure is not widened; punctate dense shadows are observed in the right posterior lobe of the liver; 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 appeared normal in shape and size, with no thickening of the gallbladder wall and no abnormal FDG uptake in the affected area.
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.
The stomach was poorly distended, with a significant amount of residual contents; the stomach wall showed no significant thickening, and FDG uptake was normal.
The intestines were poorly distended, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
The uterus is normal in shape and size, with no abnormal density shadows, and FDG uptake is normal.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly filled, but no obvious positive stones are seen.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneal region.
A small amount of pelvic effusion is present.
Muscle uptake is high throughout the body; the spinal alignment is normal, with L3/4 disc bulging.
No abnormalities are seen in bone marrow FDG metabolism.

Impression

1. a. Nasopharyngeal mass with elevated FDG metabolism, consistent with nasopharyngeal carcinoma. b. Right retropharyngeal lymph node metastasis. Bilateral deep cervical lymph node reactive hyperplasia is highly probable; follow-up is recommended.

2. Minor chronic inflammation in the left lower lobe of the lung. Incomplete thymic regression. Bilateral breast hyperplasia.

3. Calcification in the right lobe of the liver. Small amount of pelvic effusion.

4. L3/4 intervertebral disc bulge.

5. No obvious abnormalities seen on cranial scintigraphy. Physiological uptake in the glottic region.

6. Chronic inflammation of the right ethmoid sinus and right maxillary sinus, submucosal cyst of the right maxillary sinus. Right middle otitis media and mastoiditis.

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.
