Whole-body 18F-FDG PET/CT scan in a patient with Ovarian 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 tomography showed:The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The morphology and outline of both eyeballs were normal, the retrobulbar structures were clear, the optic nerves were symmetrical, and there was no abnormal FDG uptake.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and no abnormalities in FDG uptake were observed.
The palatine tonsils were symmetrical, and FDG uptake was physiological.
The morphology and structure of the laryngopharynx were normal.
The morphology and density of the bilateral parotid and submandibular glands were normal, and FDG uptake was physiological.
The thyroid gland was normal in shape and size, with uniform density, and no abnormalities in FDG uptake were observed.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
The thorax was symmetrical bilaterally, with increased lung markings.
Patchy mixed ground-glass opacities were observed in the medial and lateral basal segments of the right lower lobe, with slightly blurred margins and mildly increased FDG uptake (SUVmax = 2.2).
A few linear areas of increased density were also observed in both lungs, with no abnormal FDG uptake.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
Localized bulging of the left diaphragm was observed.
The cardiac silhouette was normal.
No esophageal dilation was observed, and no significant thickening or mass was seen in the esophageal wall; FDG uptake was not increased.
The fibrous glands in both breasts are relatively dense, and FDG uptake is not significantly abnormal.
An irregular cystic mass is seen in the lower part of the left breast, with a larger cross-sectional area of approximately 4.1*3.0cm, an average CT value of 2HU, clear borders, and absent FDG uptake.
The liver is normal in shape and size, with smooth liver margins, no widening of the hepatic fissure, and no significant abnormal density shadows in the liver parenchyma on plain CT scan.
FDG uptake is not abnormal.
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall.
Increased density and stratification within the gallbladder are observed, but local FDG uptake is not abnormal.
The pancreas is normal in shape, with no significant 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 seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
The left adrenal gland is slightly thickened, with mildly increased FDG uptake (SUVmax=2.4); the right adrenal gland shows no obvious abnormalities on contrast.
The stomach is poorly distended, with slight thickening of the gastric wall in the gastric body and mildly increased FDG uptake (SUVmax=2.1).
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
A large mixed-density mass is seen in the pelvic cavity, measuring approximately 14.6*9.7*15.3cm, with an average CT value of 21-42 HU.
The borders are relatively clear, and the solid portion shows increased FDG uptake (SUVmax=5.0).
The uterus is compressed and displaced, but no abnormal density shadows are seen in the parenchyma, and FDG uptake is normal.
No enlarged lymph nodes were observed in the abdomen, pelvis, or retroperitoneal region.
A large amount of fluid was observed in the abdominal and pelvic cavities.
The bladder was poorly filled, but no obvious positive stones were seen.
The spinal alignment was normal, with some vertebral body margins showing osteophyte formation, and a few calcifications were visible in the nuchal ligament; L4/5 and L5/S1 intervertebral disc herniations were observed, but FDG uptake was normal.

Impression

1. a. A large, mixed-density mass in the pelvic cavity with increased FDG metabolism in the solid portion, highly suggestive of ovarian cancer; please confirm with pathology. b. Large amounts of fluid in the abdomen and pelvis.

2. a. A small amount of inflammation in the lower lobe of the right lung is highly likely; anti-inflammatory treatment followed by a CT scan is recommended to rule out other possibilities. A few post-inflammatory lesions in both lungs. Localized bulging of the left diaphragm. b. Dense fibroadenomas in some parts of both breasts; a cystic mass in the lower part of the left breast, suggestive of a cyst. Please follow up with specialist examination and ultrasound.

3. Gallbladder cholestasis or sludge-like stones. Mild hyperplasia of the left adrenal gland.

4. Slight thickening of the gastric wall in the gastric body with mildly increased FDG metabolism, suggestive of chronic inflammatory changes; please confirm with gastroscopy.

5. Osteophyte formation in some vertebral bodies of the cervical, thoracic, and lumbar vertebrae; slight calcification of the nuchal ligament. L4/5 and L5/S1 intervertebral disc herniation.

6. No obvious abnormalities were found on cranial scintigraphy.

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.
