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 scan showed multiple irregular low-density nodules in the left frontal, parietal, and occipital lobes.
The largest nodule, approximately 2.8 2.3 cm, was located in the left occipital lobe and had clear borders.
FDG metabolism was elevated (SUVmax = 20.3), and a large area of edema was observed around the nodule.
No widening of the ventricles, sulci, fissures, or cisterns was observed.
The ventricles were symmetrical, and there was no midline shift.
Both eyes were symmetrical and showed no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, and there was no stenosis of the Eustachian tube openings.
The infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
Both palatine tonsils showed physiological uptake.
The morphology and structure of the laryngopharynx were normal.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
Diffuse solid nodules of varying sizes are seen in both lungs, the largest being approximately 1.7 2.4 cm in the posterior basal segment of the left lower lobe, with increased FDG metabolism (SUVmax = 15.1).
A few linear lesions are also seen in both lungs, with no abnormal FDG metabolism.
A small amount of pleural effusion is present on the right side.
Multiple enlarged lymph nodes are seen in the right hilum, para-aortic arch, and below the carina, the largest being approximately 1.2 cm in short diameter, with increased FDG metabolism (SUVmax = 7.9).
The cardiac silhouette is normal.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or lumped; FDG uptake is normal.
Multiple irregular nodules and masses are seen fused in the right breast, predominantly on the lateral side, with increased FDG metabolism (SUVmax = 12.8), and thickening of the right breast skin.
The left breast is normal, with no abnormal FDG metabolism.
Multiple enlarged lymph nodes were observed in the right axilla, right interpectoral space, and right internal mammary chain, with a short diameter of approximately 1.6 cm.
FDG metabolism was elevated, with an SUVmax of 12.4.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Multiple low-density lesions were observed within the liver, with the largest long diameter approximately 1.2 cm.
FDG metabolism was elevated, with an SUVmax of 4.5.
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.
The main pancreatic duct was not widened, and FDG uptake was not significantly abnormal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Accessory spleen formation was observed.
Both kidneys were normal in shape and size, with no significant abnormal density shadows in the parenchyma.
Several punctate and small nodular dense shadows were observed in the left renal calyx, with no significant abnormal FDG uptake.
Bilateral adrenal gland contrast was normal.
The stomach was poorly filled, with no obvious thickening of the stomach wall, and no significant abnormalities in FDG uptake.
The intestines were poorly filled, with no obvious thickening or masses in the intestinal wall, and FDG uptake was physiological.
The uterus was full in shape, with focal areas of increased FDG metabolism within the uterine cavity (SUVmax = 3.2); a cystic lesion measuring approximately 4.6 2.3 cm was observed in the right adnexa, with no abnormalities in FDG metabolism.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region, and FDG metabolism was normal.
A small amount of fluid was present in the pelvic cavity.
The spinal alignment was normal, with minor osteophyte formation at the edges of some vertebral bodies.
Bone destruction was observed in the skull base, bilateral scapulae, bilateral clavicles, right humeral head and shaft, sternum, multiple bilateral ribs, multiple vertebral bodies and appendages of the spine, sacrum, multiple areas of the pelvis, and bilateral femurs, with increased FDG metabolism (SUVmax = 21.6).
Increased FDG metabolism in the left psoas major muscle, SUVmax=18.9.

Impression

1. a. Multiple lesions in the right breast with elevated FDG metabolism, suggestive of right breast cancer. b. Multiple lymph node metastases in the right axilla, right internal mammary chain, right interpectoral space, right hilum, and mediastinum. c. Multiple intracranial metastases. Diffuse bone metastases throughout the body. Multiple lung metastases. Liver metastases. Left psoas muscle metastases.

2. A few old lesions in both lungs. Small amount of pleural effusion on the right side.

3. Accessory spleen. Left kidney stone. Small amount of pelvic effusion.

4. Physiological uptake in the uterine cavity. Possible functional cyst in the right adnexa.

5. Mild osteophyte formation in the cervical, thoracic, and lumbar spine.

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.
