Whole-body 18F-FDG PET/CT scan in a patient with Lung 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 cluster of low-density lesions with linear calcifications was observed in the right cerebellopontine peduncle, measuring approximately 2.8*1.6cm, with decreased FDG metabolism.
Multiple punctate and patchy low-density lesions were found deep within the brain with clear borders; FDG uptake was normal.
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 with no obvious abnormalities.
Thickening of the mucosa was observed in the bilateral ethmoid sinuses and the right maxillary sinus, but the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
The bilateral palatine tonsils showed physiological uptake.
The morphology and structure of the laryngopharynx were normal.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
Post-thyroid cancer surgery, a small amount of residual thyroid tissue in both lobes showed no abnormal FDG uptake.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
A soft tissue nodule, approximately 2.7*2.1cm in size, with spiculated and lobulated margins, traction on the pleura, was seen in the right middle lobe of the lung; FDG metabolism was increased, SUVmax=5.7.
A patchy lesion, approximately 2.0cm in long diameter, was seen in the right apex of the lung; FDG metabolism was not increased.
Multiple bronchiectasis was observed in both lungs, more pronounced in the right lung.
Multiple punctate, patchy, and linear shadows were observed in both lungs; FDG metabolism was not increased.
No pleural thickening was seen bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Several small lymph nodes were seen in the right hilum, pretracheal space, aortic window, and below the carina; the largest was located in the right hilum, approximately 0.5cm in short diameter; FDG metabolism was increased, SUVmax=4.7.
Calcification of some arterial walls (including coronary arteries) was observed.
The cardiac silhouette was normal.
The esophagus showed no dilation, thickening, or mass in the wall, and no increased FDG uptake.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissure.
A low-density lesion approximately 2.1 cm in diameter was seen in the right lobe of the liver on plain CT scan, with clear borders and absent FDG uptake.
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 wall and no abnormal 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 significant abnormal FDG uptake.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size; a dense shadow approximately 0.6 cm in long diameter was seen in the right kidney, with no widening of the renal pelvis, calyces, or ureter, and no significant abnormal FDG uptake.
Bilateral adrenal gland imaging showed no significant abnormalities.
The stomach was poorly distended, with no obvious thickening of the stomach wall and no significant abnormalities in FDG uptake.
The intestines were poorly distended, with continuous FDG metabolism increased in some intestinal segments (SUVmax = 10.2).
The prostate was of normal size and uniform density, with no abnormally increased FDG uptake.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
Calcification of the nuchal ligament was present.
The spinal alignment was normal, with some vertebral body margin osteophytes.
Increased FDG uptake was observed in the left shoulder periarticular region (SUVmax = 1.7).
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. a. Soft tissue lesions in the right middle lobe of the lung with increased FDG metabolism, highly suggestive of lung cancer with right hilar lymph node metastasis; please confirm with pathology. b. Reactive hyperplasia of mediastinal lymph nodes. c. Old lesion in the right apex of the lung. Multiple chronic inflammatory nodules, chronic inflammation, and sequelae in both lungs. Chronic bronchitis in both lungs, more pronounced in the right lung. Calcification of some arterial walls (including coronary arteries).

2. a. Space-occupying lesion in the right cerebellopontine angle with decreased FDG metabolism, suggestive of a schwannoma; please provide a comprehensive analysis with enhanced MRI. b. Multiple ischemic and softening lesions in the deep brain. Bilateral ethmoid sinusitis and right maxillary sinusitis.

3. Postoperative changes after thyroid cancer surgery; no signs of tumor recurrence were observed in the surgical area.

4. Cyst in the right lobe of the liver. Right kidney stone.

5. Physiological or inflammatory uptake of some intestinal segments.

6. Degenerative changes in the spine. Left frozen shoulder.

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.
