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, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG metabolism.
There was no widening of the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were normal in shape and outline, with clear retrobulbar structures, symmetrical optic nerves, and no abnormal FDG metabolism.
The right lateral and posterior walls of the nasopharynx showed irregular thickening, presenting as soft tissue nodules with indistinct borders, measuring approximately 2.6*2.1*2.1 cm.
FDG metabolism was increased, with SUVmax = 12.1.
The right pharyngeal recess and pharyngeal opening of the Eustachian tube were obliterated and protruded into the right posterior nasal cavity.
The right mastoid process showed poor pneumatization.
Slight thickening of the mucosa in the bilateral ethmoid sinuses and part of the right maxillary sinus, with intact sinus walls and absent FDG metabolism.
FDG metabolism in the oropharynx and laryngopharynx is physiological.
No abnormal contrast was observed in the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with slightly heterogeneous density, and no abnormal FDG metabolism was observed.
Small lymph nodes are visible in the bilateral deep cervical spaces, the largest with a short diameter of approximately 0.6 cm, showing slightly increased FDG metabolism, SUVmax=2.4.
Several solid miliary nodules are present in both lungs, with regular shape, clear borders, and a long diameter of approximately 0.2-0.3 cm, with no abnormal FDG uptake.
A few linear and flocculent density shadows are also seen in both lungs, with no abnormal FDG metabolism.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
Partial calcification of the arterial wall.
No obvious masses or nodules were seen in either breast; FDG metabolism was normal.
The liver showed no obvious abnormalities in shape or size; the liver margins were smooth; the hepatic fissure was not widened; no obvious abnormal density shadows were seen in the liver parenchyma on plain CT scan; FDG metabolism was normal.
The main portal vein showed no obvious widening; no dilation was seen in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size; the gallbladder wall was not thickened; local FDG metabolism was normal.
The pancreas was normal in shape; no obvious abnormal density shadows were seen in the parenchyma; the main pancreatic duct was not widened; FDG metabolism was normal.
The spleen showed no abnormalities in shape, size, density, or FDG metabolism.
Both kidneys were normal in shape and size; no obvious abnormal density shadows were seen in the parenchyma.
No widening of the renal pelvis, calyces, or ureters was observed, and FDG metabolism showed no significant abnormalities.
Bilateral adrenal gland imaging showed no significant abnormalities.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG metabolism.
Gastric distension was poor, with slight thickening of the walls in parts of the gastric body and antrum, and slightly increased FDG uptake (SUVmax = 3.2).
Intestinal distension was unsatisfactory, with increased FDG metabolism in parts of the intestine (SUVmax = 5.6).
The uterus was absent post-operatively.
The bladder was poorly distended, but no obvious positive stones were observed.
No enlarged lymph nodes were observed in the abdomen, pelvis, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes.
L4/5 and L5/S1 intervertebral disc bulges were observed, but FDG metabolism was normal.
L5/S1 intervertebral disc gas accumulation and degeneration.

Impression

1. A mass on the right lateral wall and posterior wall of the nasopharynx, with increased FDG metabolism, consistent with nasopharyngeal carcinoma. Reactive hyperplasia of bilateral deep cervical lymph nodes is highly probable; follow-up is recommended. Chronic inflammation of the right mastoid process.

2. Several small, solid, chronic inflammatory nodules in both lungs; follow-up with CT scan is recommended. A few post-inflammatory lesions in both lungs. Partial arteriosclerosis.

3. Slight thickening of the walls of part of the gastric body and antrum, with mildly increased FDG uptake, suggestive of chronic gastritis; increased FDG metabolism in part of the intestinal tract, suggestive of inflammatory or physiological uptake. Follow-up gastroscopy and colonoscopy are recommended for all of the above.

4. Osteophyte formation at the vertebral margins in some areas. L4/5 and L5/S1 intervertebral disc bulges. L5/S1 intervertebral disc pneumatosis and degeneration.

5. No obvious abnormalities were found on cranial parenchymal scintigraphy. A few inflammations in the bilateral ethmoid sinuses and right maxillary sinus.

6. The thyroid gland has uneven density; ultrasound follow-up is recommended.

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.
