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 round, slightly high-density mixed nodular lesion with indistinct borders and a long axis of approximately 0.8 cm was observed in the left occipital lobe, with increased FDG metabolism (SUVmax = 13.2).
A few patchy low-density shadows were observed around the nodule, with absent FDG metabolism.
Other punctate low-density lesions were observed in the deep brain regions bilaterally, with no significant abnormalities in FDG metabolism.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical ventricles and no midline shift.
The morphology and contours of both eyes were normal, with clear retrobulbar structures and symmetrical optic nerves bilaterally, with no abnormal FDG metabolism.
Slight thickening of the mucosa in parts of the bilateral ethmoid and maxillary sinuses was observed, with intact sinus walls and absent FDG metabolism.
No thickening of the nasopharyngeal wall was observed.
There was no stenosis of the bilateral pharyngeal recesses or Eustachian tube openings.
The infratemporal and pterygopalatine fossae structures were normal.
The bilateral parapharyngeal spaces were clear, and FDG metabolism was normal.
FDG metabolism in the oropharynx and laryngopharynx was physiological.
No abnormal contrast was observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density, and FDG metabolism was normal.
Small lymph nodes were visible in the bilateral deep cervical spaces, the largest with a short diameter of approximately 0.6 cm, and FDG metabolism was normal.
A lymph node was visible in the left supraclavicular fossa, the largest with a short diameter of approximately 0.6 cm, and FDG metabolism was increased (SUVmax = 6.2).
A few linear and flocculent density shadows were seen in both lungs, and FDG metabolism was normal.
A cystic lesion with a long diameter of approximately 1.0 cm was seen in the right middle lobe.
A very small amount of pleural effusion was present in the right pleural cavity.
No significantly enlarged lymph nodes were seen in the bilateral hilum or mediastinum.
No abnormalities were observed in the cardiac silhouette.
Some arterial walls showed calcification.
A lobulated soft tissue density mass was seen on the lateral side of the left breast, with relatively clear borders, measuring approximately 3.4*2.7*3.2cm in cross-section, showing increased FDG metabolism (SUVmax=21.2).
Another slightly dense nodule was seen above the left nipple, with indistinct borders, approximately 0.7cm in long axis, showing increased FDG metabolism (SUVmax=4.4).
The right breast showed slightly dense fibrous tissue, with no significant abnormalities in FDG metabolism.
Multiple lymph nodes were observed in the left internal mammary chain, left axilla, and left pectoral intermuscular space, the largest with a short axis of approximately 1.9cm, showing increased FDG metabolism (SUVmax=15.1).
The liver showed no significant abnormalities in shape or size, with smooth liver margins and no widening of the hepatic fissure.
CT scan revealed two low-density nodules in the liver parenchyma, with smooth margins, the larger one approximately 1.6cm in long axis, and absent FDG metabolism.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall and no abnormalities in local FDG metabolism.
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 abnormalities in FDG metabolism.
The spleen showed no abnormalities in shape, size, density, or FDG metabolism.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG metabolism was not significantly abnormal.
Bilateral adrenal gland contrast was normal.
The esophagus was not dilated, with no obvious thickening or mass in the esophageal wall, and no increased FDG metabolism.
The stomach was generally full, with no obvious thickening of the gastric wall and no obvious abnormalities in FDG metabolism.
The intestines are not fully distended, but the intestinal wall shows no obvious thickening or mass; FDG metabolism is normal.
The uterus is normal in shape and size, with no abnormal density shadows; FDG metabolism is normal.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is not fully distended, but no obvious positive stones are seen.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneum.
No obvious fluid accumulation is seen in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral body margin osteophytes.
L4/5 and L5/S1 intervertebral disc bulges; FDG metabolism is normal.
Localized bone destruction was observed in the right scapula, mid-shaft of the right humerus, left 5th and right 8th lateral ribs, right 10th posterior rib, right side of the T1 spinous process root, T4 and T12, L2 and L5, S1 vertebral body, bilateral iliac bones, and left pubic tubercle.
Increased FDG metabolism was observed, with SUVmax = 16.6.
Increased FDG metabolism was also observed in the medullary canal of the right mid-shaft humerus, with SUVmax = 5.0.

Impression

1. a. A mass in the lateral aspect of the left breast, with increased FDG metabolism, consistent with breast cancer; multiple lymph node metastases in the left internal mammary chain, left axilla, left interpectoral space, and left supraclavicular fossa. b. A slightly dense nodule above the nipple in the left breast, with increased FDG metabolism, breast cancer to be ruled out; please correlate with clinicopathology. c. Multiple bone metastases throughout the body. d. A slightly high-density nodule in the left occipital lobe, with increased FDG metabolism; contrast-enhanced MRI is recommended to rule out metastasis. Age-related brain changes, deep lacunar infarcts.

2. A bulla in the right middle lobe. A few post-inflammatory lesions in both lungs. A very small amount of pleural effusion on the right side. Partial arteriosclerosis.

3. A liver cyst.

4. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

5. Mild inflammation of the bilateral ethmoid sinuses and right maxillary sinus, and a submucosal cyst of the left maxillary sinus. Reactive hyperplasia of the deep cervical lymph nodes bilaterally.

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.
