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, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed: Normal brain morphology and structure; no abnormal density shadows were observed in the brain parenchyma; no significant abnormalities were observed 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 eyeballs were symmetrical and showed no significant abnormalities.
Thickening of the right lateral and posterior parietal walls of the nasopharynx, presenting as a soft tissue mass, with a maximum cross-section of approximately 3.0 2.4 cm, showed increased FDG metabolism (SUVmax = 24.8), involving the posterior nasal aperture and sphenoid sinus; the right pharyngeal recess was obliterated.
Thickening of the mucosa of the bilateral maxillary sinuses, right ethmoid sinus, and bilateral sphenoid sinuses was observed; no abnormalities were observed in FDG uptake.
Bilateral palatine tonsils showed physiological uptake.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in morphology and size, with uniform density; no abnormalities were observed in FDG uptake.
Multiple enlarged lymph nodes were observed in the bilateral deep cervical spaces and bilateral submandibular regions, the largest being located in the left deep cervical space, with a short diameter of approximately 1.0 cm.
FDG metabolism was increased, with SUVmax = 12.5.
A few linear opacities were observed in both lungs with clear borders; FDG uptake was normal.
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.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was normal.
The liver was normal in shape and size, with smooth borders, no widening of the hepatic fissure, and a slightly homogeneous decrease in liver density (CT value approximately 44 HU); FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall; local FDG uptake was normal.
The pancreas is 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 is normal in shape, size, density, and FDG uptake.
Both kidneys are 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 glands show no obvious abnormalities on contrast.
The stomach is poorly distended, with no obvious thickening of the stomach wall, and no obvious abnormalities in FDG uptake.
The intestines are poorly distended, with increased FDG metabolism in some intestinal segments, SUVmax=3.3 (considered physiological uptake).
The prostate is normal in size and density, with no abnormally increased FDG uptake.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneal region, and FDG metabolism is normal.
No obvious effusion is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with no osteophytes in any vertebral body, and no abnormalities in FDG uptake.

Impression

  1. a. Space-occupying lesions on the right lateral and posterior walls of the nasopharynx, with elevated FDG metabolism, consistent with active nasopharyngeal carcinoma, involving the posterior nasal aperture and sphenoid sinus. b. Left deep cervical lymph node metastasis. Reactive hyperplasia of the right deep cervical lymph nodes and bilateral submandibular lymph nodes is possible; partial metastasis needs to be ruled out, follow-up is recommended. c. Paranasal sinusitis.

  2. A few fibrotic lesions in both lungs.

  3. Mild fatty liver.

  4. No abnormalities were found on cranial scintigraphy.

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.
