Whole-body 18F-FDG PET/CT scan in a patient with Cervical 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: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
Both eyes were symmetrical, with no obvious abnormalities.
The right ethmoid sinus mucosa was thickened, while the mucosa of the other paranasal sinuses was not thickened, and the sinus walls were intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
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 was normal in morphology and structure.
Postoperative thyroid cancer surgery, thyroid gland absent.
No abnormal density shadows were seen in the surgical area, and FDG metabolism was normal.
Bilateral deep cervical spaces and submandibular lymph nodes were observed, the largest being approximately 0.5 cm in short diameter, with no abnormal FDG metabolism.
Lung markings were indistinct.
A mixed ground-glass nodule in the anterior segment of the left upper lobe, with indistinct borders, measuring approximately 1.6*1.5 cm, with a maximum CT value of 87 HU, showed increased FDG uptake (SUVmax = 7.7), and bronchial perforation was observed within it.
Several ground-glass nodules were present in both lungs, the largest located in the posterior segment of the right upper lobe, with indistinct borders, approximately 0.9 cm in long diameter, and a maximum CT value of -287 HU, with no abnormal FDG metabolism.
Several solid nodules were also present in both lungs, the largest approximately 0.3 cm in diameter, with no abnormal FDG uptake.
A few linear lesions were present in the lower lobes of both lungs, with no abnormal FDG uptake.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette appeared normal.
Some arterial walls showed calcification (including the coronary arteries).
No abnormal density shadows were observed in the bilateral breasts; FDG metabolism was normal.
No esophageal dilation was observed; the esophageal wall showed no significant thickening or mass; FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size; the liver margins were smooth; the hepatic fissures were not widened; liver density was decreased (CT value: 43 HU); a small cystic lesion, approximately 1.1 cm in diameter, was observed in the right posterior lobe of the liver; FDG uptake was normal.
The main portal vein showed no significant widening; no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size; the gallbladder wall showed no thickening; local FDG uptake was normal.
The pancreas is normal in morphology, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen's morphology, size, density, and FDG uptake are normal.
A few exudative shadows are seen around both kidneys.
A small cystic lesion, approximately 0.4 cm in diameter, is present in the left renal parenchyma.
FDG metabolism is normal.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging is normal.
The stomach is poorly filled, with thickening of the antral wall and slightly increased FDG uptake (SUVmax = 4.7).
Intestinal filling is unsatisfactory, but intestinal uptake is physiological.
An irregular soft tissue mass was observed on the cervix with indistinct borders and calcifications.
FDG uptake was increased (SUVmax = 24.2), with an uptake range of approximately 3.2*2.3*3.4cm, involving the lower segment of the uterine body.
The remaining uterine margins were not smooth.
No obvious space-occupying lesions were observed.
FDG metabolism was normal.
Small lymph nodes were observed bilaterally near the iliac vessels and bilaterally inguinally, the largest with a short diameter of approximately 0.8cm.
FDG metabolism was normal.
No obvious abnormalities were observed in the bilateral adnexa.
The bladder was poorly filled, and no obvious positive stones were observed.
Decreased bone density was observed throughout the body.
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies.
L4/5 and L5/S1 intervertebral disc bulges were observed.
The cortical margins of the right 4th anterior rib were locally distorted.
FDG metabolism was normal.
FDG metabolism in the bone marrow was normal.

Impression

1. Cervical mass with elevated FDG metabolism, suggestive of cervical cancer; please correlate with clinicopathology. Reactive hyperplasia of bilateral iliac vessels and bilateral inguinal lymph nodes.

2. a. Mixed ground-glass nodule in the anterior segment of the left upper lobe with elevated FDG metabolism, highly suggestive of inflammation; anti-inflammatory treatment followed by CT scan recommended to rule out lung cancer. b. Several ground-glass nodules in both lungs, FDG metabolism normal, suggestive of inflammation or atypical adenomatous hyperplasia; annual CT scan recommended. c. Chronic inflammatory micronodules (solid) in both lungs. A few post-inflammatory lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Postoperative changes after thyroid cancer surgery; no signs of tumor recurrence in the surgical area. Reactive hyperplasia of bilateral cervical lymph nodes.

4. Fatty liver; small cyst in the right lobe of the liver.

5. Chronic inflammatory changes in the gastric antrum; please follow up with endoscopy.

6. Osteoporosis, degenerative changes in the spine, L4/5 and L5/S1 disc bulges. Old fracture of the right fourth anterior rib.

7. Age-related brain abnormalities, deep lacunar infarcts. Chronic inflammation of the right ethmoid 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.
