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: Several slightly high-density nodules in both frontal lobes, the largest being approximately 2.2 cm in length in the left frontal lobe, with increased FDG uptake (SUVmax = 11.1), surrounded by patchy low-density shadows.
No widening of the ventricles, sulci, fissures, or cisterns was observed; local density and FDG uptake were normal; and midline structure shift was not observed.
The morphology and outline of both eyeballs were normal; retrobulbar structures were clear; optic nerves were symmetrical; and FDG uptake was normal.
No thickening of the paranasal sinus mucosa was observed; the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; FDG uptake was normal; the pharyngeal recesses were symmetrical; the Eustachian tube openings were not narrowed; the infratemporal and pterygopalatine fossae were normal; and the parapharyngeal spaces were clear; FDG uptake was normal.
The palatine tonsils were full and showed physiological FDG uptake.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region, and FDG uptake was normal.
The thorax is symmetrical, and the lung markings are clear.
A soft tissue mass measuring approximately 6.7*5.0*7.3cm is seen in the lower lobe of the right lung, with lobulated and spiculated margins, thickened adjacent pleura, and local bronchial truncation.
FDG uptake is increased, with SUVmax=15.3.
Multiple solid nodules with clear borders are seen in both lungs, the largest being approximately 0.9cm in length in the upper lobe of the right lung.
Some nodules show increased FDG uptake, with SUVmax=1.8.
Multiple ground-glass nodules are seen in the anterior and apical segments of the right upper lobe and the apical-posterior segment of the left upper lobe.
The largest, approximately 1.7*0.9cm in size, is located in the apical segment of the right upper lobe and shows mixed ground-glass density.
FDG uptake is increased, with SUVmax=1.3.
A few linear and patchy hazy shadows are seen in both lungs.
Multiple lymph nodes were observed in the right hilum, superior mediastinal intervascular space, paratracheal region, pretracheal region, posterior vena cava region, para-aortic region, subcarinal region, posterior mediastinal region, and bilateral supraclavicular regions.
The largest lymph node had a short diameter of approximately 1.3 cm, with increased FDG uptake (SUVmax = 8.6).
There was no pleural effusion or pneumothorax bilaterally.
The cardiac silhouette appeared normal.
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was not increased.
Postoperatively, the left breast showed full and dense mammary glands bilaterally.
A slightly high-density nodule with a long diameter of approximately 0.6 cm was observed in the upper inner quadrant of the left breast; FDG uptake was normal.
A glandular-like density shadow was observed in the subcutaneous tissue of the right axilla; FDG uptake was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Punctate dense shadows were observed in the right lobe of the liver; FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder appeared normal in shape and size, with no thickening of the gallbladder wall, no positive stones or obvious masses, and no abnormal FDG uptake.
The pancreas appeared normal in shape, with localized increased FDG uptake in the pancreatic tail (SUVmax=4.1).
No obvious abnormal density shadows were seen on the same CT image, and the main pancreatic duct was not widened.
The spleen appeared normal in shape and size, with no abnormal density or FDG uptake.
Both kidneys appeared normal in shape and size, with no obvious abnormal density shadows in the renal parenchyma, and no obvious abnormal FDG uptake.
The renal pelvis, calyces, and ureters were not widened, and no positive stones were seen.
Both adrenal glands appeared normal in shape and density, and no abnormal FDG uptake was seen.
Gastric distension was poor, and no obvious abnormal FDG uptake was seen.
Bowel preparation was poor; no obvious masses were seen in the bowel wall, but some bowel segments showed increased FDG uptake (SUVmax=6.0).
Post-operative ovarian teratoma surgery: The uterus was smaller in shape, with no abnormal density shadows, and no abnormal FDG uptake.
No abnormal density was observed in the bilateral adnexal regions, and FDG uptake was normal.
The bladder was adequately filled, and no positive stones or obvious masses were observed.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region, and FDG uptake was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L5/S1 intervertebral disc bulging.

Impression

1. a. A soft tissue mass in the lower lobe of the right lung with increased FDG metabolism, suggestive of lung cancer involving the adjacent pleura, accompanied by multiple metastases in both lungs. Please confirm with pathology. b. Right hilar and mediastinal lymph node metastases. Bilateral supraclavicular lymph node metastases are possible. c. A mixed ground-glass opacity nodule in the apical segment of the right upper lobe with increased FDG metabolism, suggestive of early lung cancer, but inflammatory lesions cannot be ruled out; ground-glass opacities in the anterior segment of the right upper lobe and the apical-posterior segment of the left upper lobe, with normal FDG metabolism, suggestive of atypical adenomatous hyperplasia or chronic inflammatory nodules. Annual HRCT follow-up is recommended. d. Chronic inflammation and sequelae in both lungs.

2. Multiple intracranial metastases. Please combine with enhanced MRI for comprehensive analysis.

3. Postoperative left breast surgery: Bilateral breast hyperplasia. A slightly high-density nodule in the upper inner quadrant of the left breast, with normal FDG metabolism, suggests possible fibroadenoma or lobular hyperplasia nodule. Please confirm with ultrasound or enhanced MRI. Accessory breast in the right axilla.

4. Localized elevated FDG metabolism in the pancreatic tail, with no abnormal density shadows seen on the same CT scan, suggesting a possible physiological change. Please rule out space-occupying lesions based on clinical findings and MRI. Liver calcifications.

5. Increased FDG metabolism in parts of the intestine, suggesting physiological uptake or chronic inflammation. Please follow up with endoscopy.

6. Partial vertebral osteophyte formation. L5/S1 intervertebral disc bulge.

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.
