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:Post-surgery, a metallic shadow was seen in the frontal cranial plate; patchy low-density shadows were observed in the left basal ganglia and periventricular region, with absent FDG uptake.
Enlargement of the ventricles, sulci, fissures, and cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no obvious abnormalities.
Mucosal thickening was observed in the right ethmoid sinus and right maxillary sinus; no thickening was observed in the mucosa of the remaining paranasal sinuses, and the sinus walls were intact.
The nasal septum was slightly deviated; the left nasopharyngeal wall was thickened with increased FDG uptake (SUVmax = 6.8); the left pharyngeal recess was shallow; there was no stenosis of the Eustachian tube opening; the infratemporal fossa and pterygopalatine fossa structures were normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx appear normal in shape and structure.
The thyroid gland is normal in shape and size, but its density is somewhat uneven.
A low-density nodule approximately 0.5 cm in diameter is seen in the left lobe; FDG uptake is normal.
Bilateral deep cervical spaces and submandibular lymph nodes are visible; the largest is located in the right deep cervical space, with a short diameter of approximately 0.8 cm.
FDG uptake is increased, with an SUVmax of 4.1.
Both lungs show clear lung markings and multiple solid nodules with clear borders, predominantly subpleural, the largest approximately 0.5 cm in diameter.
FDG uptake is normal.
Scattered linear lesions are present in both lungs; FDG uptake is normal.
No pleural thickening or pleural effusion/pneumothorax is observed bilaterally.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
The heart is full and enlarged.
Calcification is present in some arterial walls (including the coronary arteries).
A patchy soft tissue density shadow with indistinct borders was observed in the upper left breast, containing calcifications, measuring approximately 3.1*2.1*3.3cm.
FDG uptake was increased, with SUVmax=4.7.
No obvious mass was 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 0.6cm, and FDG metabolism was normal.
No esophageal dilation was observed, and no obvious thickening or mass was seen in the esophageal wall.
FDG uptake was not increased.
The liver showed no obvious abnormalities in shape or size, with smooth liver margins and no widening of the hepatic fissure.
Multiple calcifications were observed within the liver, the largest with a diameter of approximately 0.8cm, and FDG uptake was normal.
No significant widening of the main portal vein was observed, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder appears normal in shape and size, with a dense nodule approximately 0.9 cm in diameter within it.
The gallbladder wall is not thickened, and local FDG uptake is normal.
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 normal.
The spleen appears normal in shape, size, density, and FDG uptake.
A soft tissue density nodule approximately 0.9 cm in diameter is present adjacent to the spleen, with no abnormal FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
Bilateral adrenal gland contrast is normal.
The stomach is poorly filled, with slight thickening of the cardia, part of the gastric body, and antrum walls.
FDG uptake is slightly increased, with SUVmax = 2.3.
Intestinal distension was unsatisfactory; no obvious space-occupying lesions were observed, and the intestinal uptake was physiological.
The uterus was not visualized.
No obvious abnormalities were observed in the bilateral adnexa.
The bladder was poorly distended, but no obvious positive stones were seen.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region.
No obvious fluid accumulation was observed in the abdominal or pelvic cavities.
Generalized bone density was decreased; the spinal alignment was normal, with some vertebral marginal osteophytes, and L4/5 and L5/S1 intervertebral disc bulges.
Multiple subcutaneous calcifications were present in both buttocks.
Systemic bone marrow FDG metabolism was normal.

Impression

1. Left breast mass with elevated FDG metabolism, consistent with breast cancer; reactive hyperplasia of small axillary lymph nodes bilaterally.

2. Post-cranial surgery changes, softening lesions in the left basal ganglia and periventricular region, age-related brain changes; MRI follow-up recommended.

3. Thickening of the left nasopharyngeal wall with elevated FDG metabolism; nasopharyngitis is the primary consideration; further specialist examination recommended to rule out tumors. Chronic inflammation of the right ethmoid sinus and right maxillary sinus.

4. Nodular goiter. Reactive hyperplasia of bilateral cervical lymph nodes.

5. Chronic inflammatory nodules in both lungs; CT follow-up recommended to rule out partial metastasis. Scattered post-inflammatory lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

6. Calcifications in the liver. Gallstones. Accessory spleen.

7. Chronic inflammatory changes in part of the gastric wall; please follow up with endoscopy.

8. Osteoporosis, degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge. Multiple subcutaneous calcifications in both buttocks.

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.
