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; 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.
The eyeballs were symmetrical and without significant abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, 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 parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
Thyroid gland: Normal in shape and size, with slightly uneven density; FDG uptake not abnormal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
A ground-glass opacity of approximately 0.6 cm in long diameter was seen in the right middle lobe of the lung; the borders were indistinct, and FDG uptake was not abnormal.
Calcification was present in the apical segment of the right upper lobe.
No pleural thickening was seen bilaterally; no pleural effusion or pneumothorax was observed bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
A lymph node of approximately 0.4 cm in short diameter was seen in the cardiophrenic angle; FDG metabolism was increased, SUVmax = 3.1.
The density of the cardiac chambers was lower than that of the myocardium.
No esophageal dilatation was seen; no significant thickening or mass was seen in the esophageal wall; FDG uptake was not increased.
No significant abnormal density was seen in either breast; FDG metabolism was not abnormal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
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.
Stomach distension is poor, with no obvious thickening of the stomach wall, and no significant abnormality in FDG uptake.
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
Uterus is normal in shape, with an irregular low-density shadow measuring approximately 1.3*1.4cm in size seen in the myometrium of the posterior uterine wall; FDG uptake is normal.
A low-density lesion measuring approximately 2.53.0cm is seen in the left adnexal region, with increased FDG metabolism (SUVmax=3.8).
The bladder wall shows no abnormal thickening, and no obvious positive stones are seen within it.
Several lymph nodes are seen in the portacaval space and retroperitoneum, the largest with a short diameter of approximately 0.5cm; FDG metabolism is slightly increased (SUVmax=2.0).
Multiple flocculent thickenings are seen in the greater omentum and pelvic floor peritoneum; FDG metabolism is increased (SUVmax=10.6).
Pelvic effusion.
The spinal alignment is normal, with mild osteophyte formation at the margins of some vertebral bodies.
No abnormalities were observed in systemic bone FDG metabolism.

Impression

1. a. Thickening of the greater omentum and pelvic floor peritoneum with increased FDG metabolism suggests a high probability of metastasis; a mass in the left adnexal region with increased FDG metabolism suggests a possible ovarian tumor; peritoneal tuberculosis caused by the above lesions should be ruled out. Please consider clinicopathology and tumor markers. b. Metastasis to the cardiophrenic angle, hiatal space, and retroperitoneal lymph nodes should be ruled out. c. Pelvic effusion. Mild anemia.

2. Irregular low-density shadow in the myometrium of the posterior wall of the uterus, with no abnormal FDG uptake, suggests uterine fibroid degeneration or adenomyosis.

3. Ground-glass opacity in the right middle lobe of the lung, with no abnormal FDG uptake, suggests chronic inflammation. Calcification in the apical segment of the right upper lobe.

4. Mild osteophyte formation in some vertebrae.

5. No obvious abnormalities were found on cranial FDG imaging.

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.
