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 images showed: Normal brain morphology and structure, with punctate low-density shadows in the deep cerebral regions bilaterally; FDG uptake was normal.
Widening of some ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; midline shift was not observed.
Normal eyeball morphology and contours bilaterally; clear retrobulbar structures; symmetrical optic nerves bilaterally; FDG uptake was normal.
Thickening of the ethmoid sinus mucosa bilaterally, with intact sinus walls.
No thickening of the nasopharyngeal wall was observed; FDG uptake was normal; symmetrical pharyngeal recesses bilaterally; no stenosis of the Eustachian tube openings; normal structures of the infratemporal and pterygopalatine fossae; clear bilateral parapharyngeal spaces bilaterally; FDG uptake was normal.
Full palatine tonsils bilaterally; FDG uptake was physiological.
Normal laryngopharyngeal morphology and structure.
Normal thyroid morphology and size; uniform density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake was normal.
The thorax was symmetrical.
One pure ground-glass nodule was observed in the apical segment of the right upper lobe and the lateral basal segment of the right lower lobe, with long diameters of approximately 0.4 cm and 0.5 cm respectively, and slightly indistinct borders; FDG uptake was normal.
A few linear opacities and small patchy opacities were observed in both lungs; FDG uptake was normal.
The trachea was midline, and the trachea and segmental bronchi were patent.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions; FDG uptake was not significantly increased.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
The cardiac silhouette was normal.
The esophagus was not dilated, and the esophageal wall was not significantly thickened or swollen; FDG uptake was not increased.
The skin of the right breast is thickened.
Two small soft tissue masses are seen in the lower inner quadrant of the right breast, the larger one measuring approximately 3.0*2.1cm, with irregular shape and indistinct borders.
FDG uptake is increased, SUVmax=16.3.
Calcifications are also seen in the lower inner quadrant of the right breast.
No abnormal density shadows are seen in the left breast, and FDG uptake is normal.
Enlarged lymph nodes are seen in the right axilla and right internal mammary chain, the larger one located in the right axilla with a short diameter of approximately 2.0cm.
FDG uptake is increased, SUVmax=13.5.
The liver's shape and size are normal, with smooth liver margins and no widening of the hepatic fissure.
Multiple cystic lesions are seen in the liver parenchyma, the largest located in the left lobe with a long diameter of approximately 8.2cm.
FDG uptake is absent in these lesions.
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder's shape and size are normal, the gallbladder wall is not thickened, and no positive stones or obvious masses are seen within it.
FDG uptake is normal.
The pancreas appeared normal in morphology, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was normal.
The spleen appeared normal in morphology and size, with no abnormalities in density or FDG uptake.
Both kidneys appeared normal in morphology and size; a cystic lesion was observed in the left kidney, with a long diameter of approximately 3.2 cm, and FDG uptake was absent.
The renal pelvis, calyces, and ureters were not widened, and no positive stones were observed.
Both adrenal glands appeared normal in morphology and density, and FDG uptake was normal.
The stomach was poorly filled, and FDG uptake was normal.
Bowel preparation was poor; no obvious masses were observed in the intestinal wall, but FDG uptake was increased in some intestinal segments (SUVmax = 6.4).
The uterus appeared normal in morphology; multiple isodense nodules were observed in the uterine body, the largest with a long diameter of approximately 2.3 cm, and FDG uptake was normal.
No abnormal density was observed in the bilateral adnexa, and FDG uptake was normal.
The bladder was poorly filled, and no positive stones or obvious masses were observed.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region, and FDG uptake was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes, increased FDG uptake at the L5/S1 facet joint (SUVmax = 3.6), and L4/5 intervertebral disc bulging and pneumothorax.

Impression

1. a. Thickened skin of the right breast, mass in the lower inner quadrant of the right breast, increased FDG metabolism, suggestive of breast cancer; please refer to pathology. Calcifications in the right breast. b. Lymph node metastasis in the right axilla and right internal mammary chain.

2. Ground-glass nodules in the apical segment of the right upper lobe and the lateral basal segment of the right lower lobe, normal FDG metabolism, suggestive of chronic inflammatory nodules or atypical adenomatous hyperplasia; please refer to annual follow-up with HRCT. Chronic inflammation and sequelae in both lungs.

3. Liver cyst (one large). Left kidney cyst. Uterine fibroid.

4. Increased FDG metabolism in some intestinal segments, suggestive of physiological uptake or chronic inflammation; please refer to endoscopic follow-up.

5. Spinal degeneration. Inflammation of the L5/S1 facet joint. L4/5 intervertebral disc bulge, pneumatosis, and degeneration.

6. Bilateral deep lacunar infarcts, senile encephalopathy. Bilateral ethmoid sinusitis.

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.
