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.
There was no widening of the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no obvious abnormalities.
An irregular thickening and bulging soft tissue mass, approximately 3.7 2.5 cm, was observed on the right wall of the nasopharynx, with increased FDG metabolism (SUVmax = 17.4).
The right pharyngeal recess was obliterated, and the mass was indistinctly demarcated from the right tonsil.
Multiple enlarged lymph nodes were observed in the right retropharyngeal space, right deep cervical space, and right supraclavicular fossa, the largest with a short diameter of approximately 1.5 cm, showing increased FDG metabolism (SUVmax = 14.5).
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
The left palatine tonsil showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
Several solid micronodules were observed in both lungs, approximately 0.2-0.4 cm in long diameter, with clear borders; FDG metabolism was normal.
A few speckled and linear lesions were also observed in both lungs; FDG metabolism was normal.
No thickening of the pleura was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
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 bilateral mammary glands showed dense fibroadenomas; FDG metabolism was normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
Several punctate calcifications were observed under the capsule of the right lobe of the liver, with no abnormalities in FDG uptake.
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 no thickening of the gallbladder wall and no abnormalities in local FDG uptake.
The pancreas was 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 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, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormalities in FDG uptake.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension is poor, with no obvious thickening of the stomach wall, and no significant abnormalities in FDG uptake.
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
Uterus is full in shape, with patchy areas of increased FDG metabolism in the uterine cavity (SUVmax=2.9); a cystic lesion measuring approximately 3.12.1cm is seen in the left adnexal region, with some areas showing increased FDG metabolism (SUVmax=2.5).
Bladder distension is normal, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
A small amount of pelvic effusion is present.
The spinal alignment is normal, and the bone structure of each vertebra is intact.
No abnormalities in FDG metabolism are observed in the whole bone marrow.

Impression

1. A mass on the right lateral wall of the nasopharynx, with elevated FDG metabolism, consistent with nasopharyngeal carcinoma, possibly involving the right tonsil; multiple lymph node metastases in the right retropharyngeal space, right deep cervical space, and right supraclavicular fossa.

2. Several small, solid, chronic inflammatory nodules in both lungs; follow-up CT scan recommended to rule out other involvement. A small amount of chronic inflammation and old lesions in both lungs.

3. Calcifications in the liver. Small amount of pelvic effusion.

4. Physiological uptake in the uterine cavity. A left adnexal ovarian cyst is highly probable; follow-up ultrasound is recommended.

5. 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.
