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 scan showed: The brain morphology and structure were normal.
A patchy low-density lesion with clear borders was seen in the right basal ganglia region; FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were slightly widened; the ventricles were symmetrical, and there was no midline shift.
Both eyes were symmetrical, with no obvious abnormalities.
A cystic low-density lesion was seen in the submucosal region of the right maxillary sinus; the sinus wall was intact.
The nasopharyngeal wall was not thickened; FDG uptake was normal.
The pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear, and FDG uptake was normal.
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.
A low-density nodule measuring approximately 0.8 1.0 cm is seen in the left lobe of the thyroid gland, with relatively clear borders and increased FDG metabolism (SUVmax = 10.8).
The right lobe shows uniform density, and FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
Several solid micronodules, approximately 0.2?.3 cm in long diameter, with clear borders and normal FDG metabolism are seen in both lungs.
A few speckled, linear, and calcified foci are also seen in both lungs, with normal FDG metabolism.
No pleural thickening is seen bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
Several lymph nodes are seen in the bilateral hilar regions, pretracheal spaces, aortic windows, and below the carina, the largest being approximately 0.8 cm in short diameter, with increased FDG metabolism (SUVmax = 3.6).
The cardiac silhouette is normal.
Some arterial walls show calcification.
The esophagus showed no dilation, thickening or masses in the esophageal wall, and no increased FDG uptake.
Both breasts were normal, and FDG metabolism was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure; multiple cystic lesions were observed within the liver, the largest being approximately 1.8 cm in length, with absent FDG uptake.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall and no abnormalities in local FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormalities in FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys are normal in shape and size.
A cystic low-density lesion with a long diameter of approximately 0.8 cm is seen in the parenchyma of the right kidney.
No widening of the renal pelvis, calyces, or ureter is observed.
FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no significant abnormalities.
The stomach is poorly distended, with slight thickening of part of the stomach wall.
FDG metabolism is increased, SUVmax=3.6.
The intestines are poorly distended, with increased FDG uptake in some intestinal segments, SUVmax=7.3.
An irregular soft tissue mass measuring approximately 3.62.7 cm is seen in the left adnexal region.
FDG metabolism is increased, SUVmax=10.6.
The greater omentum, mesentery, bilateral paracolic gutter, and pelvic floor fascia show flocculent thickening, with some areas appearing as flocculent and nodular soft tissue shadows.
FDG metabolism is increased, SUVmax=5.9.
The uterine cavity is enlarged and contains fluid accumulation, with absent FDG uptake.
Bladder fullness is normal, no obvious positive stones are seen inside.
Spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 disc bulging.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Left adnexal region mass, elevated FDG metabolism, highly suggestive of ovarian cancer. Uterine cavity effusion. b. Extensive peritoneal implantation metastasis in the abdominopelvic cavity.

2. Low-density nodule in the left lobe of the thyroid gland, elevated FDG metabolism, suggestive of adenoma, but thyroid cancer cannot be ruled out; further ultrasound examination recommended.

3. a. Several small, solid, chronic inflammatory nodules in both lungs. A small amount of chronic inflammation and old lesions in both lungs. b. Reactive hyperplasia of hilar and mediastinal lymph nodes in both lungs. Calcification of some arterial walls (including coronary arteries).

4. Liver cyst. Right kidney cyst.

5. Slight thickening of part of the gastric wall, elevated FDG metabolism, suggestive of gastritis; follow-up gastroscopy recommended. Increased FDG uptake in some intestinal segments, possibly due to physiological or inflammatory uptake; endoscopic follow-up is recommended to rule out other possibilities.

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

7. Softening lesions in the right basal ganglia. Mild age-related brain changes. Submucosal cyst of the right 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.
