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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
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 significant abnormalities.
The left ethmoid sinus mucosa was slightly thickened, while the mucosa of the other paranasal sinuses was not thickened, and the sinus walls were intact.
The nasal septum was slightly deviated, but the nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear, with no abnormalities in FDG uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx were normal in morphology and structure.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Solid nodules were found in the upper lobes of both lungs and the lower lobe of the left lung, with clear borders; the largest nodule is approximately 0.3 cm in diameter.
FDG uptake was normal.
A few linear lesions were found in both lungs, with normal FDG uptake.
No pleural thickening was seen bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal; the density of the cardiac chambers was lower than that of the myocardium.
An irregular soft tissue density mass was seen in the left breast, with indistinct borders and slightly uneven density, measuring approximately 5.6*4.2*4.5 cm.
FDG uptake was increased, with SUVmax=22.3; adjacent skin was involved.
Enlarged lymph nodes in the left axilla, approximately 1.4 cm in short diameter, with increased FDG uptake (SUVmax = 12.2).
The right breast shows dense glandular tissue, with no obvious mass, and FDG metabolism is normal.
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is normal.
The liver is normal in shape and size, with smooth borders, no widening of the hepatic fissure, and no abnormal density shadows in the liver parenchyma on plain CT scan; FDG uptake is normal.
The main portal vein is not significantly widened, and there is no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
Spleen morphology, size, density, and FDG uptake were normal.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was not significantly abnormal.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
Stomach distension was poor, with slight thickening of the walls of the cardia and antrum, and increased FDG uptake (SUVmax = 3.8).
Intestinal distension was unsatisfactory, with increased FDG uptake in some intestinal segments (SUVmax = 6.9); increased FDG uptake in the anal canal (SUVmax = 5.1).
Uterus morphology and size were normal, with no abnormal density shadows.
Patchy FDG uptake in the uterine cavity was increased (SUVmax = 6.2).
A cystic lesion was observed in the left adnexal region, approximately 1.4*1.6cm in size, with increased FDG uptake at the periphery (SUVmax = 8.2).
The bladder was not fully distended, but no obvious stones were observed.
No enlarged lymph nodes were seen in the abdomen or pelvis.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, and whole-body bone density and whole-body bone marrow FDG metabolism were normal.

Impression

1. a. Left breast mass with increased FDG metabolism, adjacent skin involvement, suggestive of breast cancer; please correlate with clinicopathology; left axillary lymph node metastasis. b. Right breast hyperplasia; specialist follow-up recommended.

2. Bilateral lung chronic inflammatory micronodules; CT follow-up recommended. A few post-inflammatory lesions in both lungs. Anemia changes.

3. Possibly physiological uptake in the uterine cavity; left ovarian cyst; specialist and ultrasound follow-up recommended.

4. Chronic inflammatory changes or physiological uptake in parts of the stomach wall and intestines; hemorrhoids possible; please correlate with endoscopic follow-up.

5. No obvious abnormalities seen on cranial scintigraphy. Chronic inflammation of the left ethmoid sinus.

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.
