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 cystic low-density lesion, approximately 1.7*0.7cm in cross-section, was seen in the subcalm of the right frontal lobe, with absent FDG uptake.
No abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
No widening was seen in the ventricles, sulci, fissures, or cisterns.
The ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was seen, and the sinus walls were intact.
The nasal septum was deviated, but the nasopharyngeal wall was not thickened, and FDG uptake was not abnormal.
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 abnormal FDG uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx showed no abnormalities in morphology or structure.
The thyroid gland was normal in shape and size, with slightly uneven density; FDG uptake was normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Lung markings were clear bilaterally.
A mixed ground-glass opacity was observed in the subpleural region of the anterior basal segment of the right lower lobe, with clear borders, a long diameter of approximately 0.5 cm, and a maximum CT value of -276 HU; FDG uptake was normal.
A solid nodule was observed in the apical segment of the right upper lobe, with clear borders; the largest nodule was approximately 0.3 cm in diameter; FDG uptake was normal.
A few linear lesions were observed in both lungs; FDG uptake was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
The cardiac chamber density was slightly lower than that of the myocardium.
A soft tissue mass measuring approximately 8.9*7.4*9.1cm was observed in the left breast, with indistinct borders, heterogeneous density, and calcifications.
A central low-density necrotic area was also present.
FDG uptake was observed in a ring pattern, with SUVmax=12.6.
Adjacent skin was also involved.
A slightly enlarged lymph node in the left axilla, approximately 0.7cm in short diameter, showed increased FDG uptake, with SUVmax=2.1.
The right breast showed dense fibroadenomas with several small nodules, the largest approximately 0.8cm in diameter, some with mildly increased FDG uptake, SUVmax=1.2.
The esophagus was not dilated, and the wall was not significantly thickened or swollen.
FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
CT scan showed no significant abnormal density shadows in 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 appeared normal in shape and size, with no thickening of the gallbladder wall and no abnormal FDG uptake in the affected area.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormal FDG uptake.
Bilateral adrenal gland imaging showed no obvious abnormalities.
The stomach was poorly distended, with no significant thickening of the stomach wall and no obvious abnormal FDG uptake.
The intestines were poorly distended, with no significant thickening or mass in the intestinal wall, and FDG uptake was physiological.
The uterus is normal in shape and size, with no abnormal density shadows, and FDG uptake is normal.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly filled, but no obvious positive stones are seen.
No enlarged lymph nodes are seen in the abdomen or pelvis.
No obvious fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral marginal osteophytes.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Left breast mass with elevated FDG metabolism, consistent with breast cancer; left axillary lymph node metastasis. b. Right breast hyperplasia, possibly with hyperplastic nodules or fibroadenoma; ultrasound follow-up recommended.

2. a. Right lower lobe anterior basal segment mixed ground-glass nodule, FDG metabolism normal, suggestive of atypical adenomatous hyperplasia; HRCT follow-up every six months recommended to rule out early lung cancer. b. Right upper lobe chronic inflammatory micronodule (solid); CT follow-up recommended. A few post-inflammatory lesions in both lungs. Mild anemia.

3. Right frontal arachnoid cyst is the primary consideration; MRI follow-up recommended.

4. Partial vertebral osteophyte formation.

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.
