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; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, and no obvious abnormalities were observed.
Thickened soft tissue shadows were seen on the posterior and right lateral walls of the nasopharynx, involving both posterior nasal apertures, measuring approximately 3.6*2.9cm, with increased FDG metabolism (SUVmax=13.3).
An enlarged lymph node was seen in the right retropharyngeal space, with a short diameter of approximately 0.8cm, showing increased FDG metabolism (SUVmax=8.5).
The infratemporal fossa and pterygopalatine fossa structures were normal.
The right mastoid process showed decreased translucency.
The ethmoid and maxillary sinuses showed thickening of the mucosa, but the sinus walls were intact.
Nasal mucosa thickening.
Bilateral palatine tonsil areas show physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
Laryngopharynx morphology and structure were normal.
Thyroid gland morphology and size are normal, density is slightly uneven, FDG uptake is normal.
Multiple lymph nodes are present in the bilateral deep cervical spaces, left posterior cervical triangle, and left supraclavicular region, the largest with a short diameter of approximately 1.1 cm; some show mildly increased FDG uptake, SUVmax = 2.6.
Multiple solid micronodules are present in both lungs, with clear borders, approximately 0.2?.4 cm in diameter; scattered patchy, calcified, and linear shadows are present in both lungs; FDG uptake is normal in all cases.
No pleural thickening was seen bilaterally; no pleural effusion or pneumothorax was observed bilaterally.
Multiple soft tissue nodules and masses were observed in the left anterior mediastinum, the largest measuring approximately 10.6*9.7cm, containing punctate calcifications and necrosis.
FDG metabolism was increased, with SUVmax=10.0.
Compression of the adjacent left lung was noted.
Calcification of some arterial walls (including the coronary arteries) was observed.
The cardiac silhouette appeared normal.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth borders, no widening of the hepatic fissure, and decreased parenchymal density (CT value approximately 39 HU).
Punctate calcifications were present in the right lobe of the liver, and FDG uptake was normal.
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 or size, no thickening of the gallbladder wall, and no abnormal FDG uptake.
Mild fatty infiltration of the pancreas, no widening of the main pancreatic duct, and no significant abnormalities in FDG uptake.
No abnormalities were observed in the spleen's morphology, size, density, or FDG uptake.
Multiple low-density lesions were observed in both kidneys, with clear borders and absent FDG uptake; the largest lesion was approximately 3.7 cm in long diameter.
No widening of the renal pelvis, calyces, or ureters was observed, and no significant abnormalities in FDG uptake were observed.
No significant abnormalities were observed in bilateral adrenal glands.
Poor gastric distension, slight thickening of the gastric wall in the antrum, and slightly increased FDG metabolism (SUVmax = 1.7).
Poor intestinal distension, with no significant thickening or mass in the intestinal wall; FDG uptake was physiological.
Normal prostate size and morphology, with punctate calcifications observed; no abnormal FDG metabolism was observed.
No abnormal thickening of the bladder wall was observed, and no significant positive stones were observed.
No enlarged lymph nodes were observed in the abdominopelvic region or retroperitoneal area.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
Calcification of the nuchal ligament was present.
The spinal alignment was normal, with some vertebral body margin osteophytes.
Systemic bone FDG metabolism was normal.

Impression

1. a. Soft tissue lesions on the posterior and right lateral walls of the nasopharynx with increased FDG uptake, involving both posterior nasal apertures, consistent with nasopharyngeal carcinoma. b. Right retropharyngeal lymph node metastasis. Metastasis to the bilateral deep cervical spaces, left posterior cervical triangle, and part of the left supraclavicular lymph nodes needs to be ruled out; please follow up. c. Bilateral ethmoid and maxillary sinusitis. Nasal cavity inflammation. Right otitis media and mastoiditis.

2. Multiple lesions in the left anterior and middle mediastinum with increased FDG uptake; malignancy is the primary consideration, with high-risk thymoma and lymph node metastasis being possible. Comprehensive analysis with contrast-enhanced MRI is recommended.

3. Multiple solid micronodules in both lungs with normal FDG uptake, suggestive of chronic inflammatory nodules; please follow up with CT. Scattered chronic inflammation and remnants in both lungs. Calcification of some arterial walls (including coronary arteries).

4. Fatty liver, punctate calcifications in the right lobe of the liver. Mild fatty infiltration of the pancreas. Bilateral renal cysts. Prostatic calcification.

5. Physiological changes or inflammatory lesions in the gastric antrum; follow-up gastroscopy is recommended.

6. Spinal degenerative changes.

7. No obvious abnormalities were found on cranial FDG imaging.

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.
