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.
Multiple slightly low-density lesions were observed in the left cerebellar hemisphere, the largest measuring approximately 3.6*3.4 cm, with increased FDG uptake (SUVmax = 22.9).
Patchy low-density lesions were seen in the left frontal lobe, with no abnormal FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed.
The ventricles were symmetrical, and there was no midline shift.
Both eyes were symmetrical, with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
Slight thickening of the nasopharyngeal wall was accompanied by increased FDG uptake (SUVmax = 7.3).
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid lobes were enlarged, with multiple calcifications in both lobes, and multiple low-density nodules and masses in both lobes.
The left lobe was larger, measuring approximately 5.6*4.1cm, with unevenly increased FDG uptake (SUVmax=4.5).
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
A miliary nodule was found in the anterior segment of the right upper lobe, and a calcified nodule, approximately 0.7cm in diameter, was found in the anterior medial basal segment of the left lower lobe.
No abnormal FDG uptake was observed in either lung.
A few linear lesions were found in both lungs, with no abnormal 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, and the cardiac chamber density was lower than that of the myocardium.
Thickened skin in the left breast; a soft tissue nodule in the lower quadrant of the left breast, with indistinct borders and uneven density, measuring approximately 1.9*1.3cm, showing increased FDG uptake (SUVmax=7.6); no obvious mass in the right breast, and no abnormal FDG metabolism.
Multiple enlarged lymph nodes in the left axilla, the largest approximately 1.6cm in short diameter, showing increased FDG uptake (SUVmax=13.4).
No esophageal dilation, no obvious thickening or mass in the esophageal wall, and no increased FDG uptake.
No obvious abnormalities in liver shape and size, smooth liver margins, no widening of the hepatic fissure, and no obvious abnormal density shadows in the liver parenchyma on plain CT scan, with no abnormal FDG uptake.
No obvious widening of the main portal vein, and no dilation of intrahepatic or extrahepatic bile ducts.
Absent gallbladder.
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 no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal glands show no obvious abnormalities on contrast.
The stomach is poorly filled, with thickening of the antral wall and increased FDG uptake (SUVmax = 3.2).
The descending duodenum is thickened, with a thicker section of approximately 1.4 cm and an affected length of approximately 4.6 cm.
FDG uptake is increased (SUVmax = 8.1); intestinal filling is unsatisfactory, but intestinal uptake is physiological.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly filled, with no obvious positive stones.
The uterus is enlarged with irregular margins and visible soft tissue density bulges.
The largest bulge is located on the right anterior wall, with a long diameter of approximately 5.8 cm.
FDG metabolism is normal.
The endometrial area shows uneven density with patchy FDG uptake, SUVmax=6.1.
Retroperitoneal and mesenteric lymph nodes are visible, the largest with a short diameter of approximately 1.7 cm.
FDG uptake is increased, SUVmax=10.4.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies.
Increased bone density is observed at the relative margins of the L2/3 vertebral bodies.
Multiple lumbar intervertebral disc bulges are present.
Patchy subcutaneous shadows are present in the right groin area, with no abnormalities in FDG metabolism.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Left breast mass with increased FDG metabolism, suggestive of breast cancer; please correlate with clinicopathology. b. Multiple lymph node metastases in the left axilla, retroperitoneum, and root of the mesenteric cavity. c. Cerebellar metastasis; MRI follow-up recommended. Small softening lesion in the left frontal lobe.

2. Uterine fibroid; uneven endometrial density with patchy increased FDG metabolism, endometrial cancer to be ruled out; enhanced MRI recommended for further examination.

3. Thyroid calcifications; enlarged thyroid gland with multiple nodules and masses, increased FDG metabolism, suggestive of nodular goiter; please correlate with ultrasound.

4. Inflammatory manifestations in the antrum of the stomach and duodenum; please correlate with endoscopy to rule out other possibilities.

5. Chronic miliary lesions in the anterior segment of the right upper lobe; calcifications in the anterior medial basal segment of the left lower lobe. A few post-inflammatory lesions in both lungs. Anemia.

6. Changes after cholecystectomy.

7. Degenerative changes in the spine, L2/3 vertebral endplate inflammation. Multiple lumbar disc bulges. Chronic subcutaneous inflammation in the right groin.

8. Chronic inflammation of the nasopharynx.

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.
