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; a well-defined low-density lesion in the left temporal lobe, approximately 1.1*0.9cm in size, with no abnormal FDG metabolism.
Enlargement of the ventricles, sulci, fissures, and cisterns; symmetrical bilateral ventricles; no midline shift.
Symmetrical bilateral eyeballs with no obvious abnormalities.
Post-nasopharyngeal carcinoma treatment; no obvious space-occupying lesion in the nasopharynx; no abnormal FDG metabolism; bilateral pharyngeal recesses visualized.
Bilateral deep cervical spaces and small submandibular lymph nodes visualized, the largest with a short diameter of approximately 0.5cm; no abnormal FDG uptake.
Thickening of the mucosa in the left sphenoid sinus, bilateral ethmoid sinuses, and bilateral maxillary sinuses.
No abnormal density shadows in the bilateral parotid and submandibular glands.
Normal morphology and structure of the oropharynx and laryngopharynx.
Fluid density shadow is seen in the mastoid process of the right middle ear.
The thyroid gland is normal in shape and size, with uneven density; FDG uptake is normal.
Increased lung markings are present bilaterally, with multiple solid nodules in both lungs, with clear borders; the largest is approximately 0.4 cm in diameter.
FDG uptake is normal.
A round, air-filled cavity is present in the posterior segment of the right lower lobe, approximately 1.7 cm in diameter.
Scattered linear lesions are present bilaterally; FDG uptake is normal.
Pleural thickening is present bilaterally, but there is no pleural effusion or pneumothorax.
Small mediastinal lymph nodes are visible, the largest having a short diameter of approximately 0.7 cm; FDG uptake is increased, SUVmax = 3.8.
Cardiac silhouette is normal.
Partial arteriosclerosis is present.
No abnormal density shadows are seen in either breast; FDG metabolism is normal.
The esophagus is not dilated; continuous FDG uptake is increased throughout the entire esophageal wall, SUVmax = 4.2.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
A slightly low-density lesion, approximately 4.5*3.7cm in size, was observed in the right posterior lobe of the liver, with clear borders and background FDG uptake.
A cystic lesion, approximately 1.1cm in diameter, was observed in the left lateral lobe of the liver, with no abnormalities in FDG metabolism.
The main portal vein showed no obvious widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
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.
Left kidney atrophy; right kidney normal in shape and size, with a small cystic lesion in the right renal parenchyma, approximately 0.6 cm in diameter.
No widening of the renal pelvis, calyces, or ureter was observed.
FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no significant abnormalities.
Stomach distension was poor, with slight thickening of the cardia, part of the gastric body, and antrum walls.
FDG uptake was increased, SUVmax = 4.0.
Intestinal distension was unsatisfactory; no obvious space-occupying lesions were observed in the intestines.
Continuous FDG uptake in the ascending colon was increased, SUVmax = 6.8.
Focal FDG uptake in the anal canal was increased, SUVmax = 6.8.
Uterus was small, with no abnormal density shadows and no abnormal FDG uptake.
No significant abnormalities were observed in the bilateral adnexa.
Bladder distension was poor, with no obvious positive stones observed.
Multiple soft tissue density shadows were observed in the spinal canal at the C1-2, T2, T7, and T10-L1 levels, with increased FDG uptake (SUVmax = 13.4).
Bone destruction was also observed in the T10 vertebral body with increased FDG uptake (SUVmax = 12.0).
The spinal alignment was normal, with some vertebral body margin osteophytes, pneumodisc degeneration at L5/S1, and bulging at L4/5 and L5/S1.
No abnormalities were seen on visualization of the lower extremities.

Impression

1. a. After treatment for nasopharyngeal carcinoma, no obvious space-occupying lesions were found in the nasopharynx, and FDG metabolism was normal, suggesting that tumor activity was basically suppressed; bilateral cervical lymph node reactive hyperplasia or post-treatment changes. b. Multiple soft tissue density shadows with increased FDG metabolism in the spinal canal at the C1-2, T2, T7, and T10-L1 levels; T10 vertebral body bone destruction with increased FDG metabolism. These are considered metastatic tumors.

2. Low-density lesion in the left temporal lobe, with normal FDG metabolism, combined with contrast-enhanced MRI images from another hospital, suggests a metastatic tumor. Age-related brain changes.

3. Chronic inflammation of the left sphenoid sinus, bilateral ethmoid sinuses, and bilateral maxillary sinuses. Right otitis media/mastoid inflammation.

4. Chronic inflammatory micronodules in both lungs; CT follow-up is recommended. Right lower lobe bullae. A few post-inflammatory remnants in both lungs. Bilateral pleural thickening. Reactive hyperplasia of mediastinal lymph nodes. Partial arteriosclerosis.

5. Hemangioma of the right lobe of the liver is the primary consideration; enhanced MRI follow-up is recommended. Cyst in the left lobe of the liver. Left renal atrophy. Small cyst in the right kidney.

6. Chronic inflammatory changes or physiological uptake in the entire esophagus, part of the stomach wall, and intestines; hemorrhoidal changes; please follow up with endoscopy.

7. Degenerative changes in the spine; L5/S1 disc pneumothorax; L4/5 and L5/S1 disc bulging.

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.
