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

Under fasting conditions, 18F-FDG was administered intravenously, and the patient rested before undergoing whole-body PET/CT imaging.
The whole-body imaging showed: normal brain morphology and structure, with punctate, slightly low-density shadows in the deep brain regions; no abnormalities were observed in FDG metabolism.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
Both eyes were symmetrical and showed no obvious abnormalities.
The nasal septum was slightly deviated, but the nasal mucosa showed no significant thickening, and FDG uptake was normal.
Irregular thickening of the soft tissue on the right posterior and lateral walls of the nasopharynx was observed, with increased FDG uptake (SUVmax = 13.9), covering an area of approximately 4.9cm x 3.6cm, with an irregular surface and indistinct borders; the bilateral pharyngeal recesses were shallowed and disappeared, invading the right parapharyngeal space, bilateral posterior nasal openings and sphenoid sinuses, with destruction of adjacent skull base bone.
Multiple enlarged lymph nodes were observed in the right retropharyngeal space and bilateral deep cervical spaces, the largest measuring 1.8 cm in short diameter, with increased FDG uptake (SUVmax = 10.8).
The laryngopharynx showed no abnormalities in morphology or structure, and the parapharyngeal spaces were clearly defined.
The bilateral submandibular and parotid glands showed no abnormalities in size, shape, or density, with physiological FDG uptake.
The left lobe of the thyroid gland was enlarged with uneven density and increased FDG uptake (SUVmax = 7.6).
Both lungs showed clear lung markings, with multiple solid nodules, predominantly subpleural, the largest approximately 0.4 cm in diameter, but no abnormal FDG uptake was observed.
A few linear lesions were observed in both lungs, with no abnormal FDG uptake.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
Some arteries showed slight sclerosis.
The esophagus showed no dilation, and no significant thickening or mass was observed in the esophageal wall; FDG uptake was not increased.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, with a dense nodule within the gallbladder, approximately 1.6 cm in length.
The gallbladder wall showed no thickening, and local FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with a cystic lesion in the middle of the right kidney, approximately 1.1 cm in length, showing absent FDG uptake.
High-density shadows were seen in the renal pelvis, calyces, ureter, and bladder.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was adequately filled, with slight thickening of the gastric cardia and antrum walls, and increased FDG uptake (SUVmax = 4.1).
Intestinal distension was unsatisfactory; no local masses were observed, and FDG uptake was normal.
The prostate was enlarged, approximately 6.4 cm in length, with calcifications visible; FDG uptake was not abnormally elevated.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The L1 vertebral body showed slight posterior displacement, with osteophyte formation at some vertebral margins; L4/5 intervertebral disc herniation was present.
FDG uptake of the entire skeleton was normal.

Impression

1. A mass in the nasopharynx with elevated FDG metabolism, consistent with nasopharyngeal carcinoma and invasion of the adjacent skull base; multiple lymph node metastases in the right retropharyngeal space and bilateral deep cervical spaces.

2. Enlarged left thyroid lobe with heterogeneous density and elevated FDG metabolism; thyroid cancer to be ruled out; further ultrasound examination recommended.

3. Chronic inflammatory micronodules in both lungs. A few post-inflammatory lesions in both lungs. Minor arteriosclerosis in some arteries.

4. Gallstones. Right renal cyst. Residual contrast agent in the urinary tract. Benign prostatic hyperplasia with calcification.

5. Chronic inflammatory changes in the cardia and antrum of the stomach; please follow up with endoscopy.

6. Mild posterior slippage of the L1 vertebral body. Degenerative changes in the spine; L4/5 disc herniation.

7. Age-related brain; deep lacunar infarcts; please combine with MRI examination.

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.
