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 scan showed: The brain morphology and structure were normal.
A soft tissue nodule, approximately 2.2*1.7cm in size, with clear borders and uneven density, was observed in the left temporal lobe, showing increased FDG uptake (SUVmax=7.6).
A patchy low-density area was observed in the surrounding brain parenchyma.
Another soft tissue nodule, approximately 1.0*0.8cm in size, with increased FDG uptake (SUVmax=6.3), was also seen in the sellar region.
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.
Thickening of the mucosa was observed in the right frontal sinus, both ethmoid sinuses, and both maxillary sinuses.
A cystic shadow was seen in the sphenoid sinus.
Nasal mucosa thickening, slight thickening of the right nasopharyngeal wall with increased FDG uptake (SUVmax = 2.8), symmetrical pharyngeal recesses, no stenosis of the Eustachian tube openings, normal structures of the infratemporal and pterygopalatine fossae, clear bilateral parapharyngeal spaces with no abnormal FDG uptake.
Bilateral palatine tonsils show physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is enlarged with uneven density, containing multiple low-density nodules, the largest located in the right lobe, approximately 1.3 cm in diameter, with no abnormal FDG uptake.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Both lungs show clear lung markings.
Multiple solid nodules are present in both lungs, the largest being approximately 0.7 cm in diameter in the lateral segment of the right middle lobe.
FDG uptake is normal.
Patchy shadows are observed paravertebrally in the right lower lobe with increased FDG uptake (SUVmax = 4.0).
Calcifications are present in the apical-posterior segment of the left upper lobe and the posterior-basal segment of the right lower lobe.
Scattered linear lesions are present in both lungs, with normal FDG uptake.
A cystic shadow containing air is seen at the right posterior border of the upper trachea.
No pleural thickening is observed bilaterally, and there is no pleural effusion or pneumothorax.
Multiple lymph nodes are visible in the bilateral hilar regions, pretracheal space, para-aortic arch, aortopulmonary window, subcarinal region, and bilateral supraclavicular fossa.
The largest has a short diameter of approximately 1.4 cm and increased FDG uptake (SUVmax = 4.8).
The cardiac silhouette is normal.
Calcification is present in some arterial walls (including the coronary arteries).
Post-operative findings: Right breast cancer surgery, right breast absence, no abnormal density shadows seen in the surgical area, FDG metabolism normal.
Left breast: No abnormal density shadows seen, FDG metabolism normal.
Esophageal dilation, no significant thickening or mass seen in the esophagus, FDG uptake normal.
Liver morphology and size normal, smooth liver margins, no widening of the liver fissure, slightly decreased liver density, punctate dense shadows in the right anterior lobe, FDG uptake normal, several cystic lesions in the liver, the largest located in the right posterior lobe, approximately 1.0 cm in diameter, FDG metabolism normal.
Portal vein trunk no significant widening, no dilation of intrahepatic or extrahepatic bile ducts.
Gallbladder morphology and size normal, gallbladder wall no thickening, local FDG uptake normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size.
The left kidney has a low-density lesion containing fatty components in the parenchyma, with a long diameter of approximately 0.9 cm.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal glands show no obvious abnormalities on contrast imaging.
The stomach is poorly distended, with no obvious thickening of the stomach wall, and FDG uptake is not significantly abnormal.
The intestines are poorly distended, with continuous increased FDG uptake in the sigmoid colon and rectum (SUVmax = 6.8).
The uterus has irregular margins, an intrauterine device (IUD) has been inserted, and FDG uptake is not abnormal.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly distended, with no obvious positive stones observed.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
Multiple osteolytic bone destruction with increased FDG uptake was observed in the right 3rd and 9th ribs, left 3rd and 7th ribs, multiple vertebral bodies and appendages of the spine, sacrum, left iliac bone, left pubis, and upper left femur (SUVmax = 7.1).
Decreased bone density was observed throughout the body.
The spinal alignment was normal, with marginal osteophyte formation in some vertebral bodies and disc bulging at L3/4, L4/5, and L5/S1.
Patchy FDG uptake was observed bilaterally around the shoulders (SUVmax = 1.8).

Impression

1. a. Postoperative changes after right breast cancer surgery, no signs of tumor recurrence. b. Multiple bone metastases throughout the body (see description for details). c. Left temporal lobe metastasis; possible sellar region lesion. Further enhanced MRI is recommended for all of the above. d. Multiple lymph nodes in the hilum, mediastinum, and bilateral supraclavicular fossa show increased FDG metabolism, suggesting likely reactive hyperplasia; partial metastasis is pending. Follow-up is recommended.

2. Chronic inflammatory nodules in both lungs. Inflammation in the lower lobe of the right lung, calcifications in both lungs, scattered post-inflammatory remnants in both lungs. Tracheal diverticulum. Calcification of some arterial walls (including coronary arteries).

3. Fatty liver, calcifications in the right lobe of the liver, liver cysts. Angiomyolipoma of the left kidney. Intrauterine device (IUD) insertion, possible uterine fibroids.

4. Chronic inflammatory changes or physiological uptake in parts of the intestine.

5. Thyroid enlargement with multiple nodules, FDG metabolism normal, suggestive of nodular goiter.

6. Osteoporosis, degenerative changes in the spine, L3/4, L4/5, L5/S1 intervertebral disc bulging. Bilateral frozen shoulder.

7. Chronic inflammation of the right frontal sinus, bilateral ethmoid sinuses, and bilateral maxillary sinuses, submucosal cyst of the sphenoid sinus. Nasal mucosal thickening, chronic inflammation of the right lateral wall of the nasopharynx.

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.
