Whole-body 18F-FDG PET/CT scan in a patient with Breast 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 images showed: Normal brain morphology and structure, with punctate, slightly low-density shadows in the deep brain regions; no abnormal FDG metabolism was observed.
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 right maxillary sinus mucosa was observed, but no thickening was observed in the mucosa of the other paranasal sinuses; the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; the palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and structure.
The parotid and submandibular glands were normal in morphology and density, and FDG uptake was physiological.
The thyroid gland was normal in morphology and size, with slightly uneven density and bilateral calcifications; FDG uptake was normal.
The bilateral deep cervical spaces, submandibular, and submental lymph nodes were visualized; the largest had a short diameter of approximately 0.6 cm, and FDG metabolism was normal.
Both lungs show clear lung markings.
Small solid nodules, approximately 0.5 cm in diameter, are present in the lateral segment of the right middle lobe and the anteromedial and lateral basal segments of the left lower lobe.
No abnormal FDG uptake was observed.
Scattered linear lesions are present in both lungs, with no abnormal FDG uptake.
No pleural thickening or pleural effusion/pneumothorax is observed bilaterally.
The cardiac silhouette is normal.
Partial arteriosclerosis is present.
The esophagus is not dilated, and the wall shows no significant thickening or mass; FDG uptake is not increased.
A soft tissue nodule measuring approximately 1.6*1.2 cm is present below the left nipple, with increased FDG uptake (SUVmax = 9.9).
Another soft tissue nodule measuring approximately 0.8*0.7 cm is present on the left anterior chest wall, with increased FDG uptake (SUVmax = 3.9).
No obvious mass or nodule is seen in the right breast; FDG metabolism is not significantly abnormal.
Multiple enlarged lymph nodes were observed in the left axilla, left interpectoral space, left supraclavicular fossa, and para-aortic arch, the largest measuring approximately 2.6 cm in short diameter.
FDG uptake was increased, with an SUVmax of 9.7.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissures.
Plain CT scan showed no significant abnormal density shadows within the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys had slightly irregular borders, with no significant abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters showed no widening, and FDG uptake was normal.
Bilateral adrenal glands showed no significant abnormalities on contrast imaging.
The stomach is adequately full, with slight thickening of the gastric wall in the antrum.
FDG uptake is slightly elevated, with SUVmax = 2.8.
Intestinal fullness is unsatisfactory; no masses are observed, and FDG uptake is normal.
The uterine margins are not smooth, but FDG uptake is normal.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly full, but no obvious positive stones are seen.
Patchy shadows are seen in the left inguinal region, but FDG metabolism is normal.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneum.
No significant fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral margin osteophytes.
L4/5 intervertebral disc herniation is present, but FDG uptake is normal.
FDG uptake of the entire skeleton shown is normal.

Impression

1. Left breast mass with elevated FDG metabolism, suggestive of breast cancer; please confirm clinicopathological findings. Multiple lymph node metastases in the left axilla, left interpectoral space, left supraclavicular fossa, and para-aortic arch.

2. Chronic inflammatory nodules in both lungs. Scattered post-inflammatory lesions in both lungs. Partial arteriosclerosis.

3. Possible uterine fibroids; please confirm with ultrasound examination. Postoperative changes in the left groin.

4. Chronic inflammatory changes in the gastric antrum; please confirm with endoscopic follow-up.

5. Degenerative changes in the spine; L4/5 disc herniation.

6. Uneven thyroid density; bilateral lobular calcifications; ultrasound follow-up recommended.

7. Deep lacunar infarcts in the brain. Chronic inflammation of the right maxillary sinus. Reactive hyperplasia of bilateral cervical 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.
