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, with punctate low-density lesions in the deep bilateral cerebral regions; no significant abnormalities were observed in FDG uptake.
Enlargement of the ventricles, sulci, fissures, and cisterns was observed; the ventricles were symmetrical bilaterally, and there was no midline shift.
Normal eyeball morphology and contours bilaterally; clear retrobulbar structures; symmetrical optic nerves bilaterally; no abnormal FDG uptake.
Bilateral mastoid hypoplasia.
Slight thickening of the mucosa in parts of the bilateral ethmoid and maxillary sinuses; intact sinus walls; absent FDG uptake.
No thickening of the nasopharyngeal wall; symmetrical palatine tonsils bilaterally; physiological FDG uptake.
Normal laryngopharyngeal morphology and structure.
Normal morphology and density of the bilateral parotid and submandibular glands; physiological FDG uptake.
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, or submental region.
An irregular soft tissue density nodule was observed at the opening of the bronchus in the anterior segment of the left upper lobe at the left hilum, fusing with the left hilar lymph node to form a mass, with a cross-sectional size of approximately 2.5*1.8*2.0cm.
FDG metabolism was increased, with SUVmax=13.0, and bronchial truncation was observed within it.
Several ground-glass opacities were observed in the apical-posterior segment of the left upper lobe, with a long diameter of approximately 0.3-0.7cm, and FDG metabolism was normal.
Solid micronodules were observed in the apical-posterior segment of the left upper lobe and the lateral basal segment of the right lower lobe, with a long diameter of approximately 0.2-0.3cm, and FDG uptake was normal.
A few linear and flocculent density shadows were also observed in both lungs, with FDG uptake normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Small lymph nodes were visualized in the right hilum and mediastinum (pretracheal, post-vena cava, aortic window, parapulmonary arch, and subcarinal), with the largest having a short diameter of approximately 0.6 cm.
FDG metabolism was normal.
The cardiac silhouette was normal.
Some arterial walls showed calcification (including the coronary arteries).
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was not increased.
Small lymph nodes were visualized in the left axilla, with the largest having a short diameter of approximately 0.6 cm.
Some showed slightly increased FDG metabolism, with SUVmax = 2.7.
The liver showed disproportionate left and right lobes, with wavy liver margins and widened hepatic fissures.
CT scan revealed a high-density shadow under the capsule of the right posterior lobe of the liver; FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
Gallbladder: No abnormalities in shape or size, no thickening of the gallbladder wall, and no abnormalities in local FDG uptake.
Pancreas: Normal shape, no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
Spleen: No abnormalities in shape, size, density, or FDG uptake.
Kidneys: Normal shape and size, 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 glands: No obvious abnormalities observed on contrast.
Stomach: Moderately full, slightly thickened antral wall, slightly increased FDG uptake, SUVmax = 2.1.
Intestinal: Poorly full, no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The prostate is slightly enlarged, with a transverse diameter of approximately 4.0 cm.
No obvious abnormal density shadows were seen in the parenchyma, and FDG uptake was normal.
The bladder is poorly filled, and no obvious positive stones were seen within it.
Fluid density shadows were present in both scrotums, but FDG metabolism was absent.
No enlarged lymph nodes were seen in the abdomen, pelvis, or retroperitoneal region.
No obvious effusion was seen in the abdomen or pelvis.
Postoperative changes were observed after left inguinal hernia repair.
The spinal alignment is normal, with calcification of the nuchal ligament and osteophyte formation at the margins of some vertebral bodies.
The L1 vertebral body is flattened with changes following bone cement injection.
L4/5 and L5/S1 intervertebral disc bulges were observed, but FDG uptake was normal.

Impression

1. a. A mass at the bronchial opening in the anterior segment of the left upper lobe of the lung, fused with the left hilar lymph nodes, with increased FDG metabolism, consistent with central lung cancer. Reactive hyperplasia of the right hilar, mediastinal, and left axillary lymph nodes is highly probable; follow-up is recommended. b. Several ground-glass opacities in the apical-posterior segment of the left upper lobe, suggestive of chronic inflammatory nodules or atypical adenomatous hyperplasia; annual HRCT follow-up is recommended. c. Chronic inflammatory nodules (solid) in the apical-posterior segment of the left upper lobe and the lateral basal segment of the right lower lobe. Scattered chronic inflammation and remnants in both lungs. Partial arteriosclerosis (including coronary arteries).

2. Manifestations of liver cirrhosis. Subcapsular calcification in the right posterior lobe of the liver. Mild prostatic hyperplasia. Bilateral hydrocele. Postoperative changes following left inguinal hernia repair.

3. Chronic antral gastritis.

4. Degenerative changes in the spine. L1 vertebral body compression with changes following bone cement injection. L4/5 and L5/S1 intervertebral disc bulging.

5. Age-related brain changes, deep lacunar infarcts in the brain. Minor inflammation of bilateral ethmoid and maxillary sinuses. Bilateral mastoid hypoplasia.

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.
