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 tomography 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, and no abnormalities in FDG uptake were 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.
The thyroid gland was normal in shape and size, with uniform density, and no abnormalities in FDG uptake were observed.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
The thorax was symmetrical bilaterally, with increased lung markings.
An irregular solid nodule, approximately 0.9 cm in long diameter, was seen in the anteromedial basal segment of the left lower lobe, showing increased FDG uptake (SUVmax = 3.1).
A thin-walled, irregularly shaped, air-filled sac, approximately 1.8 cm in long diameter, was observed proximal to the nodule, seemingly communicating with a bronchus; FDG uptake was normal.
A few linear opacities were observed in the remaining lungs, with normal FDG uptake.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
Several lymph nodes were visualized in the bilateral hilar and mediastinal regions (tracheovascular space in the superior mediastinum, para-aortic arch, aortopulmonary window, and subcarinal region) and bilateral supraclavicular fossa.
The largest was located subcarinal, approximately 1.2 cm in short diameter, with increased FDG uptake (SUVmax = 13.6).
A roundish low-density lesion, approximately 1.5*1.0cm in size, with an average CT value of 7 HU, is seen in the supracardiac recess region.
The lesion has clear borders and decreased FDG uptake.
The cardiac silhouette appears normal.
The esophagus shows no dilation, wall thickening, or mass; FDG uptake is not increased.
The bilateral mammary glands exhibit relatively dense and unevenly distributed fibroadenomas, without obvious masses or nodules; FDG uptake is normal.
The liver shows no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
A slightly low-density nodule, approximately 1.8cm in long diameter, with an average CT value of 43 HU, is seen in the upper segment of the left lateral lobe of the liver on plain CT scan; the lesion has clear borders and decreased FDG uptake compared to background levels.
A roundish low-density lesion, approximately 2.4cm in long diameter, with clear borders and absent FDG uptake, is seen in the upper segment of the right anterior lobe of the liver.
The main portal vein shows no significant widening, and intrahepatic or extrahepatic bile ducts are not dilated.
The gallbladder's shape and size are normal, the gallbladder wall is not thickened, and local FDG uptake is normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma, the main pancreatic duct is not widened, and FDG uptake is normal.
The spleen's shape, size, density, and FDG uptake are normal.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma, the renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
The left adrenal gland is slightly enlarged, with increased FDG uptake (SUVmax = 3.2); the right adrenal gland shows no obvious abnormalities on contrast.
The stomach is generally full, with no obvious thickening of the stomach wall, but some areas of the stomach wall show increased FDG uptake (SUVmax = 5.7).
The intestines are poorly full, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
Post-comprehensive treatment for cervical cancer: No obvious abnormal density shadows or abnormally increased FDG uptake were seen in the surgical area.
No enlarged lymph nodes were seen in the abdomen, pelvis, or retroperitoneal region; a lymph node was seen in the left inguinal region, with a short diameter of approximately 0.7 cm, and slightly increased FDG uptake (SUVmax = 2.9).
A small amount of fluid was seen in the pelvic cavity.
The bladder was adequately filled, and no obvious positive stones were seen.
The spinal alignment was normal, with some vertebral body margin osteophytes.
A small patchy bone density shadow with slight mobility was seen at the anterior superior margin of the L4 vertebral body.
FDG uptake was decreased in the lower lumbar and sacrococcygeal vertebrae (post-radiotherapy changes).
L4/5 intervertebral disc herniation was present, but FDG uptake was not abnormal.

Impression

1. Post-comprehensive treatment for cervical cancer: No clear signs of tumor recurrence were observed in the surgical area. Enlarged lymph nodes in the left groin with increased FDG metabolism suggest reactive hyperplasia; metastasis is not ruled out. Close follow-up is recommended. Small amount of pelvic effusion.

2. a. Irregular nodules with increased FDG metabolism in the anterior medial basal segment of the left lower lobe, newly added compared to the previous image, are highly suggestive of metastasis. Please follow up with CT scans and perform a biopsy if necessary. b. Multiple lymph nodes in the bilateral hilar and mediastinal regions and bilateral supraclavicular fossae show increased FDG metabolism, newly added compared to the previous image, suggesting lymph node metastasis. c. A slightly enlarged air-filled cavity in the left lower lobe, with normal FDG metabolism, suggests possible bronchial cystic dilatation. Please follow up regularly with CT scans.

3. A few fibrotic lesions in both lungs. A cyst in the superior pericardial recess. Bilateral breast hyperplasia.

4. A slightly low-density nodule in the upper segment of the left lateral lobe of the liver, with decreased FDG metabolism, roughly similar to the previous scan, suggestive of a hemangioma; please confirm with contrast-enhanced MRI. Liver cyst. Possible mild hyperplasia of the left adrenal gland.

5. Increased FDG metabolism in part of the gastric wall, suggestive of physiological or inflammatory changes; please confirm with gastroscopy. No obvious space-occupying lesions in the intestines; please confirm with colonoscopy follow-up.

6. Osteophyte formation in some vertebral bodies of the spine; persistent epiphysis of the L4 vertebral body. L4/5 intervertebral disc herniation.

7. No obvious abnormalities seen on cranial scintigraphy.

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.
