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; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities in FDG uptake were observed.
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.
A small amount of mucosal thickening was observed in the right maxillary sinus, but the sinus wall was intact.
Both palatine tonsils showed physiological uptake.
The morphology and structure of the laryngopharynx were normal.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density, and no abnormal FDG uptake was observed.
Diffuse thickening was observed in the left and right walls and the posterior and superior walls of the nasopharynx, presenting as an irregular soft tissue mass with increased FDG metabolism (SUVmax = 11.7), invading the posterior nasal cavity and bilateral pterygopalatine fossa, with destruction of adjacent skull base bone.
Multiple enlarged lymph nodes were observed in the bilateral retropharyngeal and deep cervical spaces, the largest measuring approximately 1.2 cm in short diameter, with mildly increased FDG metabolism (SUVmax = 10.6).
Several solid micronodules were observed in both lungs, approximately 0.2-0.3 cm in long diameter, with clear borders; FDG metabolism was normal.
A few linear and punctate lesions were also observed in both lungs; FDG metabolism 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 esophageal wall was not significantly thickened or swollen; FDG uptake was not increased.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissure; the liver parenchyma density was decreased, with a CT value of approximately 49 HU; FDG metabolism was normal.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, and the gallbladder wall was not thickened; 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 no obvious abnormal density shadows in the parenchyma; the renal pelvis, calyces, and ureters were not widened; and FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was poorly distended, with no obvious thickening of the stomach wall; and FDG uptake was normal.
The intestines were poorly distended, with no obvious thickening or masses in the intestinal wall; FDG uptake was physiological.
The prostate was normal in size and density; and FDG uptake was not abnormally increased.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region; FDG metabolism was normal.
No obvious fluid accumulation was seen in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral osteophytes and Schmorl's nodes, but no abnormalities were observed in FDG uptake.

Impression

1. A mass in the nasopharynx with elevated FDG metabolism, consistent with nasopharyngeal carcinoma, invading the posterior nasal aperture, bilateral pterygopalatine fossa, and adjacent skull base; multiple lymph node metastases in the bilateral retropharyngeal and deep cervical spaces.

2. Several solid, chronic inflammatory micronodules in both lungs; follow-up is recommended to rule out other confounding lesions. Minor chronic inflammation and old lesions in both lungs.

3. Mild fatty liver.

4. Partial vertebral osteophyte formation and Schmorl's nodes.

5. No abnormalities seen on cranial scintigraphy. Minor chronic inflammation in the right maxillary sinus.

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.
