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: a few punctate low-density shadows in the deep bilateral brain regions, with no significant abnormalities in FDG uptake.
Enlargement of the ventricles, sulci, fissures, and cisterns was observed, with symmetrical bilateral ventricles and no midline shift.
Bilateral eyeballs were symmetrical and without significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, with no abnormalities in FDG uptake.
Bilateral pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormalities in FDG uptake.
Bilateral palatine tonsils showed physiological uptake.
The morphology and structure of the laryngopharynx were normal.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density, and no abnormalities in FDG uptake.
No enlarged lymph nodes were observed bilaterally in the neck, and FDG metabolism was normal.
Several solid micronodules, approximately 0.2-0.3 cm in long diameter, with clear borders, were observed in both lungs, with normal FDG metabolism.
Scattered linear and punctate lesions were also observed in both lungs, with normal FDG metabolism.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
Several lymph nodes were observed in the bilateral hilum, pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region, the largest with a short diameter of approximately 1.0 cm, showing increased FDG metabolism (SUVmax = 4.2).
The cardiac silhouette was normal.
Calcification of some arterial walls (including coronary arteries) was observed.
No esophageal dilation was observed, and no significant thickening or mass was seen in the esophagus; FDG uptake was not increased.
Multiple irregular masses were observed in the right breast, the largest measuring approximately 9.2 5.4 cm, with increased FDG metabolism (SUVmax = 16.3), and significant thickening of the right breast skin was observed.
Multiple enlarged lymph nodes were observed in the right axilla and right internal mammary chain, the largest with a short diameter of approximately 1.6 cm, showing increased FDG metabolism (SUVmax = 8.9).
The left breast was normal, with no abnormal FDG metabolism.
Several small lymph nodes were observed in the left axilla, with a short diameter of approximately 0.5 cm, and no abnormal FDG metabolism.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
A patchy dense shadow was observed in the left lobe of the liver, with no abnormal FDG uptake.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
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 abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormal FDG uptake.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Gastric distension was poor, with no significant thickening of the gastric wall and no obvious abnormalities in FDG uptake.
Intestinal distension was poor, with increased continuous FDG metabolism in the colon and rectum (SUVmax = 5.3).
An air-filled cavity was observed in the descending duodenum, with no abnormalities in FDG metabolism.
The uterus had an irregular outline, with a cystic lesion on the cervix, approximately 1.0 cm in length, showing absent FDG uptake.
No abnormal FDG metabolism was observed in the bilateral adnexa.
The bladder was generally distended, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneum, and FDG metabolism was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral marginal osteophytes and L4/5 and L5/S1 intervertebral disc bulges, but FDG uptake was normal.
Increased FDG metabolism was observed around both shoulder joints (SUVmax = 4.5).

Impression

1. a. Multiple lesions in the right breast with increased FDG metabolism, consistent with breast cancer. b. Multiple lymph node metastases in the right axilla and right internal mammary chain. Reactive hyperplasia of lymph nodes in the left axilla.

2. Several small chronic inflammatory nodules (solid) in both lungs. Scattered chronic inflammation and old lesions in both lungs. Reactive hyperplasia of lymph nodes in the hilar and mediastinal regions of both lungs. Calcification of some arterial walls (including coronary arteries).

3. Calcification in the left lobe of the liver. Diverticulum in the descending part of the duodenum.

4. Continuous increased FDG metabolism in the colon and rectum, considered to be inflammatory or physiological uptake.

5. Possible uterine fibroids; Nabothian cysts of the cervix.

6. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges. Bilateral frozen shoulder.

7. A few ischemic lesions in the deep bilateral brain regions, age-related brain changes.

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.
