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:The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The morphology and outline of both eyeballs were normal, the retrobulbar structures were clear, the optic nerves were symmetrical, and there was no abnormal FDG uptake.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; the palatine tonsils were symmetrical, and FDG uptake was physiological.
The morphology and structure of the laryngopharynx were normal.
The morphology and density of the bilateral parotid and submandibular glands were normal, and FDG uptake was physiological.
Bilateral inferior turbinate hypertrophy was observed.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
An irregular, mixed ground-glass opacity nodule, approximately 1.8*1.4cm in cross-sectional size, was observed in the lateral/posterior basal segment of the right lower lobe; FDG metabolism was normal.
A few linear and flocculent density shadows were also observed in both lungs; FDG uptake was normal.
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 was normal.
No esophageal dilation, significant wall thickening, or mass was observed; FDG uptake was not increased.
No significant masses or nodules were observed in either breast; FDG metabolism was normal.
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 abnormalities in FDG uptake.
Intestinal distension is poor; several slightly high-density nodules and mass-like shadows are seen in the transverse colon lumen, with indistinct borders and uneven density within.
The largest has a cross-sectional size of approximately 3.0*3.6cm, with increased FDG metabolism (SUVmax=14.0).
Increased FDG uptake is also observed in parts of the colon and rectum (SUVmax=13.1).
Strip-like areas of increased FDG metabolism are seen in the uterine cavity (SUVmax=10.8).
A cystic-solid mixed-density mass is seen at the cervical-body junction, with relatively clear borders, but the boundary with the anterior rectal wall is indistinct in some areas.
The cross-sectional size is approximately 7.0*5.5*7.9cm, with septa within.
The solid portion shows unevenly increased FDG metabolism (SUVmax=8.1).
Several slightly enlarged lymph nodes were observed in the pelvic wall, the largest measuring approximately 1.5*1.2cm in cross-section.
FDG metabolism was increased, with SUVmax = 5.3.
No obvious abnormalities were seen in the bilateral adnexa.
The bladder was poorly filled, but no obvious positive stones were observed.
No enlarged lymph nodes were seen in the retroperitoneal region.
No obvious effusion was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with L5/S1 intervertebral disc bulging, but FDG uptake was normal.

Impression

1. a. A cystic-solid mixed-density mass is seen at the cervical-body junction, with unevenly increased FDG metabolism in the solid portion, suggestive of malignancy, accompanied by pelvic lymph node metastasis. Please confirm the diagnosis with pathological examination. b. Strip-like areas of increased FDG metabolism within the uterine cavity, suggestive of physiological changes. Further enhanced MRI is recommended to rule out endometrial lesions.

2. Irregular mixed ground-glass opacities in the lateral/posterior basal segment of the right lower lobe, suggestive of lung cancer. A few chronic inflammations and remnants in both lungs.

3. a. Several slightly high-density nodules and mass-like shadows in the transverse colon lumen, with increased FDG metabolism, suggestive of intestinal contents. Follow-up colonoscopy is recommended to rule out other possibilities. b. Increased FDG metabolism in the remaining colon and rectum, suggestive of physiological uptake or chronic inflammatory changes.

4. L5/S1 intervertebral disc bulge.

5. No obvious abnormalities were found on cranial scintigraphy. Bilateral inferior turbinate hypertrophy was observed.

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.
