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: A lobulated soft tissue mass was seen near the left hilum, with a maximum cross-sectional area of approximately 3.3*5.0*6.5cm.
The mass had spiculated margins, cavitation, and bronchial truncation signs.
Adjacent pleural thickening was observed, with punctate calcifications.
FDG metabolism was elevated (SUVmax = 12.6).
Compression of some adjacent bronchi was observed, and a wedge-shaped consolidation was seen distal to the mass.
Multiple small solid nodules, approximately 0.2-0.4cm, were seen in both lungs, with normal FDG metabolism.
Scattered patchy and linear shadows were seen in both lungs, with normal FDG metabolism.
An air-filled cavity, approximately 0.6*1.0cm in size, was seen in the subpleural region of the posterior segment of the right lower lobe, with thick walls and normal FDG metabolism.
Slight pleural thickening was observed bilaterally.
Enlarged lymph nodes were visible in the left hilum, the largest measuring approximately 1.5 cm in short diameter, with increased FDG metabolism and an SUVmax of 7.62.
Multiple lymph nodes were visible in the mediastinum and right hilum, the largest in the mediastinum (4R) measuring approximately 0.9 cm in short diameter, with no significant increase in FDG metabolism.
The heart size was normal.
A few punctate low-density shadows were seen in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma, and FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened; there was no midline shift.
The shape and outline of both eyeballs were normal, the retrobulbar structures were clear, and FDG metabolism was normal.
Mild thickening of the right maxillary sinus mucosa was observed, with no abnormal FDG metabolism.
No significant thickening of the remaining paranasal sinus mucosa was observed; the sinus walls were intact, and FDG metabolism was normal.
No significant thickening of the soft tissues on both sides of the nasopharynx was observed; the pharyngeal recesses were symmetrical; and FDG metabolism was normal.
The palatine tonsils were full bilaterally, with normal FDG uptake.
The morphology and structure of the laryngopharynx were normal, and the parapharyngeal spaces were clear.
The size, shape, and density of the bilateral parotid and submandibular glands were normal, with normal FDG uptake.
The thyroid gland was normal in shape and size, with no obvious abnormal density shadows; and FDG metabolism was normal.
Small submandibular lymph nodes were visible bilaterally; the larger one had a short diameter of approximately 0.7 cm on the right, and FDG uptake was normal.
The esophagus was not dilated; the esophageal wall was not significantly thickened or swollen; and FDG metabolism was not increased.
The stomach was well-filled, with no obvious abnormal thickening or swollen masses; and FDG metabolism was normal.
Intestinal filling was unsatisfactory; localized thickening was observed in the sigmoid colon and rectum; FDG metabolism was increased, with SUVmax = 3.2.
The liver's shape and size are normal, with smooth borders and no widening of the hepatic fissure.
No obvious abnormal density shadows are seen in the liver parenchyma, and FDG metabolism is normal.
No dilation of intrahepatic bile ducts is observed.
The gallbladder shows increased density, but FDG metabolism is normal, including in the gallbladder fossa.
The peripancreatic spaces are clear, with no obvious abnormal density shadows in the parenchyma and no abnormal FDG metabolism.
The spleen's shape and size are essentially normal, with no abnormal density or FDG metabolism.
The bilateral adrenal glands' shape, size, and density are normal, and local FDG metabolism is normal.
The bilateral kidneys are normal in shape and size, with no obvious abnormal density shadows in the renal parenchyma and no obvious abnormal FDG metabolism.
No widening of the renal pelvis, calyces, or ureters is observed, and no positive stones are seen in the affected areas.
The bladder is adequately full, with no obvious localized thickening or mass in the wall, and no positive stones are found in the cavity.
The prostate gland is normal in shape and size, and no focal abnormal increase in FDG metabolism is observed.
Small retroperitoneal lymph nodes are visible, the largest having a short diameter of approximately 0.5 cm, and FDG metabolism is normal.
No obvious effusion is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with narrowing of intervertebral spaces in some lumbar vertebrae, osteophyte formation at the margins of some vertebral bodies and facet joints, and cystic low-density shadows visible in the endplates of some vertebral bodies, but FDG metabolism is normal.
L4/5 intervertebral disc bulge.
L5/S1 intervertebral disc protrudes posteriorly, compressing the dural sac.
FDG metabolism is increased around the left hip joint, SUVmax = 4.5.

Impression

1. a. Left hilar mass, elevated FDG metabolism, suggestive of central lung cancer with obstructive inflammation or atelectasis; please confirm with pathological examination. b. Left hilar lymph node metastasis. Highly likely reactive hyperplasia of mediastinal and right hilar lymph nodes; follow-up recommended. c. Bilateral chronic inflammatory micronodules; follow-up recommended. Scattered chronic inflammation and remnants in both lungs. Subpleural bullae in the posterior segment of the right lower lobe. Slight pleural thickening bilaterally.

2. Localized thickening of the sigmoid colon and rectum, elevated FDG metabolism, suggestive of inflammatory polyps; colonoscopy recommended to rule out tumors.

3. Possible cholestasis; ultrasound follow-up recommended. Reactive hyperplasia of small retroperitoneal lymph nodes.

4. Degenerative changes in the spine. Lumbar vertebral endplate inflammation. L4/5 disc bulge. L5/S1 disc herniation. Left hip periarthritis.

5. Few ischemic lesions in the deep bilateral brain; age-related brain, MRI recommended. Slight chronic inflammation of the right maxillary sinus. Reactive hyperplasia of bilateral submandibular lymph nodes.

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.
