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:Normal brain morphology and structure, no abnormal density shadows in the brain parenchyma, and normal FDG uptake.
Mild widening of some ventricles, sulci, fissures, and cisterns, with no abnormal local density or FDG uptake, and no midline shift.
Normal morphology and outline of both eyeballs, clear retrobulbar structures, and normal FDG uptake.
No thickening of the paranasal sinus mucosa, and the sinus walls were intact.
Soft tissue thickening of the right lateral nasopharyngeal wall, with increased FDG uptake (SUVmax = 8.1).
Full palatine tonsils bilaterally, with increased FDG uptake (SUVmax = 12.7).
Normal morphology and structure of the laryngopharynx, and clear parapharyngeal spaces.
The thyroid gland is normal in shape and size, with uneven density and increased FDG uptake (SUVmax = 5.3).
Multiple lymph nodes are visible in the left retropharyngeal space, bilateral deep cervical spaces, bilateral posterior cervical triangles, and bilateral supraclavicular fossae.
Some are enlarged and swollen.
The largest is located in the left supraclavicular fossa, with an irregular shape and a size of approximately 2.0 1.2 cm.
FDG uptake is increased (SUVmax = 9.7).
Scattered multiple solid nodules of varying sizes are seen in both lungs, with clear borders.
The largest is located in the lateral segment of the right middle lobe, with a diameter of approximately 0.6 cm and cavitation.
FDG uptake is increased (SUVmax = 2.2).
A few linear shadows are seen in the right middle lobe.
No significant pleural thickening or pleural effusion is observed bilaterally.
Increased FDG uptake was observed in small lymph nodes at the right hilum, right superior tracheoesophageal groove, pretracheal vena cava, and para-aortic arch (SUVmax = 5.2).
Increased FDG uptake was also observed in small lymph nodes in the left internal mammary chain (SUVmax = 5.3).
The heart size was normal, with a small amount of pericardial effusion; the intracardiac chamber density was lower than that of the myocardium.
Following left breast cancer surgery, no obvious abnormal soft tissue shadows were observed in the surgical area or ipsilateral axilla; FDG uptake was normal.
The right breast showed dense fibroadenoma; FDG uptake was normal.
Lymph nodes in the right axilla were observed, the largest measuring approximately 1.0 0.9 cm; FDG uptake was normal.
The liver was enlarged with smooth borders; the hepatic fissure was not widened.
Multiple slightly low-density nodules and masses were observed in the liver parenchyma, with indistinct borders.
Some were fused into clusters, the largest being located in the right lobe of the liver, with a maximum axial cross-section of approximately 10.4 6.9 cm.
FDG uptake was increased, with SUVmax = 10.2.
No dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was poorly filled, with no positive stones or obvious masses observed.
FDG uptake in the gallbladder fossa was normal.
The peripancreatic spaces were clear, with no obvious abnormal density shadows in the parenchyma.
The pancreatic duct was not widened, and FDG uptake was normal.
The spleen was of normal shape and size, with no abnormal density or FDG uptake.
The bilateral adrenal glands were of normal shape, size, and density, with no abnormal local FDG uptake.
The bilateral kidneys were of normal shape and size, with no obvious abnormal density shadows in the renal parenchyma and no obvious abnormal FDG uptake.
No widening of the renal pelvis, calyces, or ureter was observed bilaterally, and no positive stones were seen locally.
The bladder was adequately filled, with no obvious localized thickening or mass in the wall, and no positive stones were seen within the lumen.
The uterus was normal in shape and size, with decreased density in the uterine cavity and increased FDG uptake (SUVmax = 5.1).
A low-density oval lesion with a long diameter of approximately 2.8 cm and a thin cyst wall was seen in the left adnexa, with no abnormal FDG uptake.
A cystic-solid mass with an indistinct border and an increased FDG uptake in the solid portion was seen in the right adnexa, with an increased FDG uptake (SUVmax = 10.3).
The esophagus was not dilated, with no obvious thickening or mass in the wall, and no increased FDG uptake.
The stomach was well-filled, with no abnormal FDG uptake.
The intestines were not satisfactorily filled, with no localized mass, but increased FDG uptake in some intestinal segments (SUVmax = 8.2).
Several enlarged and swollen lymph nodes were observed in the portacaval space and retroperitoneally adjacent to the aorta, with the former being the largest.
FDG uptake was increased, with SUVmax = 10.5.
No significant effusion was observed in the abdominal or pelvic cavities.
Multiple osteolytic bone destruction foci were observed in the right humerus, both femurs, right scapula, right clavicle, sternum, some ribs on both sides, multiple vertebrae and their appendages, both iliac bones, both acetabula, and both ischial tuberosities, predominantly in the vertebral bodies.
Some foci showed slight soft tissue shadows at their edges, with increased FDG uptake (SUVmax = 11.6).

Impression

1. a. Postoperative left breast cancer surgery, no clear signs of tumor recurrence were observed in the surgical area. b. Thickening of soft tissue on the right nasopharyngeal wall, increased FDG metabolism, malignancy to be ruled out, please combine with specialist examination. c. Multiple lesions in the liver, increased FDG metabolism, considered malignant tumor, metastasis is highly likely, enhanced MRI examination is necessary. d. Cystic-solid lesion in the right adnexa with increased FDG metabolism in the solid part, neoplastic lesion is considered possible, physiological changes to be ruled out; cystic lesion in the left adnexa, no increased FDG metabolism; physiological uptake in the uterine cavity is highly likely. Please combine the above with enhanced MRI examination. e. Metastasis to the left retropharyngeal space, bilateral deep cervical spaces, bilateral posterior cervical triangles, bilateral supraclavicular fossa, left internal mammary chain, hilar space and retroperitoneal lymph nodes, and possible metastasis to the right hilar and mediastinal lymph nodes.? f. Multiple lung metastases. Multiple bone metastases throughout the body.

2. A few fibrotic lesions in the right middle lobe of the lung. Dense glandular tissue in the right breast, reactive hyperplasia of the right axillary lymph nodes. Small amount of pericardial effusion. Signs of anemia.

3. Inflammatory or physiological uptake in some intestinal segments; endoscopic re-examination is necessary if required.

4. Brain parenchyma is not fully developed; no obvious abnormalities were seen on cranial FDG imaging. Physiological uptake is likely in both palatine tonsils.

5. Uneven thyroid density with increased FDG metabolism, suggesting possible nodular goiter or adenoma; please combine with ultrasound and thyroid function tests.

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.
