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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, and no obvious abnormalities were observed.
There was slight mucosal thickening in the left maxillary sinus, but the sinus wall was intact.
The nasopharyngeal wall was not thickened, and FDG uptake was not abnormal.
The 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 abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Scattered solid micronodules were found in the left lower lobe and right middle lobe, and calcifications were observed in the right upper lobe; FDG uptake was normal in both cases.
Small amount of pleural effusion was present bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
Some arterial walls showed calcification.
The cardiac silhouette was normal.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was not increased.
The bilateral mammary glands had dense fibroadenomas; FDG metabolism was normal.
The liver was normal in shape and size, with smooth borders; the hepatic fissure was not widened; no significant abnormal density shadows were seen in the liver parenchyma on plain CT scan; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder appeared normal in shape and size, with no thickening of the gallbladder wall and no abnormal FDG uptake in the affected area.
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.
The stomach was poorly distended, with no significant thickening of the stomach wall and no obvious abnormal FDG uptake.
The intestines were poorly distended, with no significant thickening or mass in the intestinal wall, and FDG uptake was physiological.
The uterus is normal in shape, with no abnormal density shadows, and no abnormally increased FDG uptake.
The bladder wall shows no abnormal thickening, and no obvious positive stones are seen within.
Soft tissue shadows are seen in each bilateral adnexal region, the left one being larger, approximately 3.0 2.3 cm, with increased FDG metabolism (SUVmax = 7.6).
Multiple irregular soft tissue nodules and masses are seen in the hepatogastric space, the lower margin of the right lobe of the liver, the bilateral paracolic gutter, the superior mesentery of the pelvis, and the rectouterine pouch.
The largest is located in the right paracolic gutter, with a CT value of approximately 40 HU and a size of approximately 8.4*4.4*15.0 cm, with increased FDG metabolism (SUVmax = 7.0).
There is a large amount of fluid accumulation in the abdomen and pelvis.
The spinal alignment is normal, with mild osteophyte formation at the margins of some vertebral bodies.
Systemic bone FDG metabolism is normal.

Impression

1. Bilateral adnexal lesions with elevated FDG metabolism, suggestive of malignancy, most likely ovarian cancer; please correlate with clinicopathology. Extensive peritoneal and pelvic metastases. Significant abdominal and pelvic effusion.

2. Scattered chronic inflammatory micronodules in the left lower lobe and right middle lobe, calcification in the right upper lobe. Small amount of bilateral pleural effusion. Calcification of some arterial walls.

3. Bilateral breast proliferative changes; specialist and ultrasound examination recommended.

4. Mild osteophyte formation in some vertebrae.

5. No obvious abnormalities on cranial FDG scintigraphy. Minor chronic inflammation of the left maxillary sinus.

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.
