Whole-body 18F-FDG PET/CT scan in a patient with Liver 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: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
Slight widening of the ventricles, sulci, fissures, and cisterns was observed; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
Poor pneumatization was observed in the left mastoid process.
No thickening of the paranasal sinus mucosa was observed; the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; no abnormalities were observed in FDG uptake; the pharyngeal recesses were symmetrical bilaterally; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and no abnormalities were observed in FDG uptake.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland was normal in morphology and size, with uniform density; no abnormalities were observed in FDG uptake.
No enlarged lymph nodes were observed bilaterally in the neck; no abnormalities in FDG metabolism were observed.
Diffuse solid nodules were observed in both lungs, the largest measuring approximately 2.6 cm in length, with clear borders and increased FDG metabolism (SUVmax = 7.2).
A few linear and punctate lesions were also observed in both lungs, with no abnormal FDG metabolism.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the hilum or mediastinum bilaterally.
The cardiac silhouette was normal.
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass; FDG uptake was not increased.
Both breasts were normal, with no abnormal FDG metabolism.
The liver was significantly enlarged, with an irregular outline and widened hepatic fissures.
Multiple low-density nodules and masses were observed within the liver, most prominent in the right lobe, with the largest measuring approximately 9.7 cm in length; FDG metabolism was increased (SUVmax = 9.3).
The portal vein was not clearly visualized.
The gallbladder was not clearly visualized.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was not significantly abnormal.
The spleen is significantly enlarged, occupying approximately 11 costal units, 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 imaging shows no obvious abnormalities.
The stomach is poorly distended, with no obvious thickening of the gastric wall, and FDG uptake is normal.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The uterus is normal in shape, with an intrauterine device present, and FDG uptake is not abnormally increased.
No abnormal FDG metabolism is observed in the bilateral adnexa.
The bladder is generally distended, with no obvious positive stones.
Multiple enlarged lymph nodes are seen in the porta hepatis and para-aortic region, the largest with a short diameter of approximately 1.5 cm, showing increased FDG metabolism (SUVmax = 3.9).
There is a large amount of fluid accumulation in the abdomen and pelvis.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies and L4/5 and L5/S1 intervertebral disc bulges.
There is discontinuity in the cortical bone of the right third posterior rib with increased FDG metabolism (SUVmax = 3.6); multiple bone destructions are found in the sternum, multiple vertebral bodies and appendages of the spine, the left femoral head, the right acetabulum, the left pubis, and the left ilium, with increased FDG metabolism (SUVmax = 4.3).

Impression

1. a. Multiple space-occupying lesions in the liver, with increased FDG metabolism, suggestive of malignancy, most likely primary liver cancer. b. Multiple lymph node metastases in the hilum and retroperitoneum. Diffuse metastases in both lungs. Extensive bone metastases throughout the body (pathological fracture of the right 3rd posterior rib). c. Liver cirrhosis; splenomegaly. Large amounts of fluid in the abdomen and pelvis.

2. A few chronic lesions and old lesions in both lungs.

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

4. Mild age-related brain changes. Sclerotic mastoid process on the left side.

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.
