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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed the following: Brain morphology and structure were normal; no abnormal density shadows were observed within the brain parenchyma, and FDG uptake was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
The nasal septum was slightly deviated; the nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, and there was no stenosis of the Eustachian tube openings.
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 observed in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx showed no abnormalities 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.
Lung markings are clear bilaterally; several solid nodules are present in both lungs, with clear borders, the largest being approximately 0.3 cm in diameter; FDG uptake is normal.
Calcification is present in the apical segment of the right upper lobe; a few linear lesions are present in both lungs; FDG uptake is normal.
No pleural thickening is seen bilaterally; no pleural effusion or pneumothorax is present bilaterally.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
Cardiac silhouette is normal.
Partial arteriosclerosis is present.
A right clavicular port has been inserted.
Following chemotherapy for left breast cancer, an irregular soft tissue nodule and mass were observed in the upper outer quadrant of the left breast.
The nodule had indistinct borders and uneven density, with the largest measuring approximately 3.3*2.7*2.6cm.
FDG uptake was increased, with an SUVmax of 5.8.
No abnormal density shadows were seen in the right breast, and FDG metabolism was normal.
Small lymph nodes were observed in both axillae, the largest with a short diameter of approximately 0.7cm.
FDG metabolism was normal.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth liver margins, no widening of the hepatic fissure, and decreased liver density (CT value: 39 HU).
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 was absent.
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, with punctate dense shadows in the right renal calyx.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal glands show no significant abnormalities on contrast imaging.
The stomach is poorly filled, with slight thickening of the antral wall and slightly increased FDG uptake (SUVmax = 2.7).
The intestines are poorly filled, with no obvious space-occupying lesions, and exhibit physiological uptake.
The uterus is full, with irregular margins and visible soft tissue density bulges; FDG uptake is not abnormal.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly filled, with no obvious positive stones.
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.
The spinal alignment was normal, with mild osteophyte formation at the margins of some vertebral bodies.
Local discontinuity of the coccygeal cortex margin was observed, accompanied by increased FDG uptake, SUVmax = 3.0.

Impression

1. Left breast cancer chemotherapy followed by a mass in the left breast with increased FDG metabolism, suggesting continued tumor activity; follow-up is recommended. Bilateral axillary lymph node reactive hyperplasia is highly probable.

2. Chronic inflammatory micronodules in both lungs; CT follow-up is recommended. A few post-inflammatory lesions in both lungs. Partial arteriosclerosis.

3. Fatty liver. Post-cholecystectomy changes. Small kidney stone in the right kidney. Uterine fibroids.

4. Chronic inflammatory changes in the gastric antrum; endoscopic follow-up is recommended.

5. Mild vertebral osteophyte formation. Possible coccyx fracture.

6. No obvious abnormalities were found on cranial scintigraphy.

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.
