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: Normal brain morphology and structure, with punctate, slightly low-density shadows in the deep brain regions; no abnormalities were observed in FDG metabolism.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; no midline shift was observed.
Bilateral eyeballs were symmetrical, with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
Nasal septum was deviated, but no significant thickening of the nasal mucosa was observed, and FDG uptake was normal.
Irregular thickening of the soft tissue on the posterior and lateral walls of the nasopharynx, with increased FDG uptake (SUVmax = 15.1), covering an area of approximately 3.6cm x 2.6cm.
The surface is irregular and the borders are indistinct.
The bilateral pharyngeal recesses are shallow, invading the bilateral posterior nasal openings.
No destruction of the adjacent skull base bone is observed.
Small lymph nodes are visible in the bilateral submandibular and deep cervical spaces, the largest being located in the right deep cervical space with a short diameter of approximately 0.6cm.
FDG uptake is slightly increased (SUVmax = 2.3).
The morphology and structure of the laryngopharynx are normal, and the parapharyngeal space is clear.
The size, shape, and density of the bilateral submandibular glands and the left parotid gland are normal, with physiological FDG uptake.
A soft tissue nodule with calcification is seen within the right parotid gland, with clear borders, measuring approximately 2.2 x 1.9cm, with increased FDG uptake (SUVmax = 10.9).
Anterior to this nodule is a 1.4 x 0.7cm soft tissue nodule with normal FDG uptake.
Increased density shadow is seen in the mastoid process of the right middle ear.
The thyroid gland is normal in shape and size, but its density is somewhat heterogeneous; FDG uptake is normal.
Multiple solid nodules are seen in both lungs, the largest being approximately 0.5 cm in long diameter; FDG metabolism is not increased.
Multiple reticular changes are seen in the subpleural region of both lungs, with calcification in the posterior segment of the right upper lobe, multiple air-filled cavities in both lungs, and a few scattered linear lesions in both lungs; FDG uptake is normal.
The pleura is slightly thickened bilaterally, with a localized nodular protrusion on the left pleura, approximately 1.5*0.7 cm in cross-section; FDG uptake is normal.
There is no pleural effusion or pneumothorax bilaterally.
Multiple lymph nodes are visible in the pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region; the largest is approximately 0.9 cm in short diameter; FDG uptake is normal.
The cardiac silhouette is normal.
The aortic arch is locally widened, with partial aortic wall calcification.
Linear dense shadows are seen along the coronary artery course.
The esophagus shows no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver's shape and size are normal, with smooth borders, no widening of the hepatic fissure, and no obvious abnormal density shadows in the liver parenchyma on plain CT scan; FDG uptake is normal.
The main portal vein shows no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder's shape and size are normal, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct is not widened, and FDG uptake is normal.
The spleen's shape, size, density, and FDG uptake are normal.
Both kidneys are normal in shape and size.
A cystic lesion is present at the upper pole of the right kidney, with a long diameter of approximately 4.9 cm.
FDG uptake is absent.
No widening of the renal pelvis, calyces, or ureter is observed, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no significant abnormalities.
The stomach is poorly distended, with no significant thickening of the gastric wall, and FDG uptake is not significantly abnormal.
The intestines are poorly distended, with no significant thickening or mass in the intestinal wall, and FDG uptake is physiological.
The prostate is full, with calcifications visible, and FDG uptake is not abnormally increased.
The bladder is poorly distended, with no obvious positive stones.
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.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Systemic bone marrow FDG metabolism is normal.

Impression

1. Nasopharyngeal mass with increased FDG metabolism, consistent with nasopharyngeal carcinoma. Right deep cervical lymph node metastasis to be ruled out; reactive hyperplasia of other cervical lymph nodes is possible. Follow-up is recommended.

2. Right parotid gland soft tissue nodule with calcification and increased FDG metabolism, suggestive of mixed tumor, malignancy to be ruled out; please confirm with pathology. Anterior to it is a soft tissue nodule with normal FDG uptake, considered benign.

3. a. Bilateral chronic inflammatory micronodules in the lungs. Interstitial changes in both lungs, bilateral emphysema, calcification in the right upper lobe, and a few post-inflammatory remnants in both lungs. b. Slight thickening of the pleura bilaterally, with a localized nodular protrusion on the left pleura; normal FDG uptake suggests a high probability of benign nodule, follow-up is recommended. Reactive hyperplasia of mediastinal lymph nodes. c. Localized widening of the aortic arch, aneurysm to be ruled out; enhanced CT scan recommended; partial aortic wall calcification; changes after coronary stent placement.

4. Right renal cyst. Benign prostatic hyperplasia with calcification.

5. Degenerative changes in the spine, L4/5 and L5/S1 disc bulges.

6. Age-related brain, deep lacunar infarcts; follow-up with MRI. Right otitis media/mastoid inflammation.

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.
