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 normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; local density and FDG uptake were normal; and there was no midline shift.
The bilateral eyeballs had normal morphology and outlines; the retrobulbar structures were clear; the bilateral optic nerves were symmetrical; and FDG uptake was normal.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; FDG uptake was normal; the bilateral pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal fossa and pterygopalatine fossa structures were normal; the bilateral parapharyngeal spaces were clear; and FDG uptake was normal.
The bilateral palatine tonsils were full and showed physiological FDG uptake.
The laryngopharynx had normal morphology and structure.
No abnormal visualization was observed in the bilateral salivary glands.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
Multiple lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, and left supraclavicular region; the largest has a short diameter of approximately 0.6 cm; FDG uptake is normal.
Multiple ground-glass nodules are seen in the apical segment of the right upper lobe, the apical-posterior segment of the left upper lobe, and the dorsolateral segment of the right lower lobe; the largest, located in the apical-posterior segment of the left upper lobe, has a long diameter of approximately 0.7 cm, with indistinct borders and a maximum CT value of approximately -587 HU; FDG uptake is normal.
Multiple solid nodules with a long diameter of approximately 0.3-0.5 cm are seen in the right upper lobe and both lower lobes; FDG uptake is normal.
A few linear opacities are seen in both lungs.
The trachea is midline, and the trachea and the lumen of each lobe and segmental bronchus are patent.
Multiple lymph nodes were observed in the bilateral hilar and mediastinal regions, some with calcification, the largest measuring approximately 0.6 cm in short diameter, with some showing increased FDG uptake (SUVmax = 5.0).
No pleural thickening was observed bilaterally, and trace amounts of pleural effusion were present bilaterally.
The cardiac silhouette appeared normal.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
Both breasts were full and dense, with no abnormal density shadows, and no abnormal FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissures.
Multiple cystic lesions were observed in the liver parenchyma, the largest located in the left medial lobe with a long diameter of approximately 0.7 cm, and no abnormal FDG uptake was observed.
Calcification was observed in the right lobe of the liver.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
Gallbladder: No abnormalities in shape or size, no thickening of the gallbladder wall, increased density within the gallbladder, and no abnormal FDG uptake.
Pancreas: No abnormalities in shape, no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no abnormal FDG uptake.
Spleen: No abnormalities in shape or size, density, or FDG uptake.
Kidneys: No abnormalities in shape or size, no obvious abnormal density shadows in the renal parenchyma, and no obvious abnormal FDG uptake.
No widening of the renal pelvis, calyces, or ureters, and no positive stones were observed.
Adrenal glands: No abnormalities in shape or density, and no abnormal FDG uptake.
Poor gastric filling, with increased FDG uptake in some gastric walls (SUVmax = 4.1).
Poor bowel preparation, with no obvious masses in the intestinal wall, but increased FDG uptake in some intestinal segments (SUVmax = 6.3).
Soft tissue nodules were seen in the right adnexal region, and a soft tissue mass was seen in the left adnexal region.
The left lesion measures approximately 7.4*5.2cm, with uneven density, indistinct borders, and unevenly increased FDG uptake (SUVmax=15.6).
The boundary with the uterus is unclear.
Increased FDG uptake is observed in the endometrial area and upper cervix (SUVmax=19.4).
Multiple small lymph nodes are seen in the retroperitoneum and mesentery, the largest with a short diameter of approximately 0.5cm; FDG uptake is normal.
The L3 and L4 vertebral bodies are posteriorly displaced, with osteophyte formation at some vertebral margins.
The L5/S1 intervertebral space is narrowed, and the cortical bone at the relative vertebral margins is rough.
L3/4 and L4/5 intervertebral disc bulges, and L5/S1 intervertebral disc accreta occurs.
Nuchal ligament calcification is present.

Impression

1. Bilateral adnexal soft tissue lesions with increased FDG metabolism, increased FDG metabolism in the endometrial area and upper cervix, all suggestive of malignancy, with a high probability of cancer. Please confirm with pathology. Reactive hyperplasia of retroperitoneal and mesenteric lymph nodes is highly probable; please follow up to rule out other possibilities.

2. a. Ground-glass nodule in the apical-posterior segment of the left upper lobe is suggestive of atypical adenomatous hyperplasia, early lung cancer to be ruled out; HRCT follow-up every six months is recommended. Ground-glass nodules in the apical segment of the right upper lobe and the posterior segment of the right lower lobe are suggestive of chronic inflammatory nodules or atypical adenomatous hyperplasia; please confirm with annual HRCT follow-up. b. Chronic inflammatory nodules (solid) in the right upper lobe and both lower lobes. Bilateral pulmonary fibrosis. Reactive hyperplasia of both hilar and mediastinal lymph nodes. Micropleural effusion bilaterally.

3. Bilateral breast hyperplasia; ultrasound follow-up is recommended.

4. Liver cysts, liver calcifications. Cholestasis of the gallbladder.

5. Increased FDG metabolism in parts of the stomach wall and intestines, possibly due to physiological uptake or chronic inflammation; please follow up with endoscopy.

6. Spinal degeneration. Lumbar instability. L5 and S1 vertebral endplate inflammation. L3/4 and L4/5 intervertebral disc bulging, L5/S1 intervertebral disc pneumatosis and degeneration.

7. No obvious abnormalities seen on cranial scintigraphy. Reactive hyperplasia of bilateral deep cervical interspaces, submandibular, and left supraclavicular lymph nodes.

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.
