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, and resting, 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.
Both eyeballs were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
The left inferior turbinate was hypertrophied, but 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.
Both palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear.
Ground-glass nodules are present in the apical-posterior segment of the left upper lobe, the lateral segment of the right middle lobe, and the posterior segment of the left lower lobe.
The largest nodule is located in the apical-posterior segment of the left upper lobe, with a long diameter of approximately 0.5 cm and a maximum CT value of -484 HU; FDG uptake is normal.
A few linear lesions are present in the inferior lingular segment of the left upper lobe and the right middle lobe; FDG uptake is normal.
No pleural thickening was observed bilaterally; no pleural effusion or pneumothorax was observed bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
Cardiac silhouette is normal.
Partial arteriosclerosis is present.
Bilateral breast tissue is increased and dense; no abnormal density shadows were observed; FDG metabolism is normal.
Multiple small lymph nodes were observed in both axillae, with a short diameter of approximately 0.8 cm.
FDG metabolism was normal.
The esophagus showed no dilation, wall thickening, or mass; FDG uptake was normal.
The liver was normal in shape and size, with smooth borders, no widening of the hepatic fissure, and decreased density (CT value: 44 HU).
A subcapsular cystic lesion was observed in the right posterior lobe of the liver, with a long diameter of approximately 1.7 cm; FDG uptake was normal.
The main portal vein was normal in size and shape; no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was normal in shape and size; the gallbladder wall was normal in thickness; local FDG uptake was normal.
The pancreas was normal in shape; no abnormal density shadows were observed in the parenchyma; the main pancreatic duct was normal in size; FDG uptake was normal.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly filled, with slight thickening of the walls of the cardia, part of the gastric body, and antrum.
FDG uptake is slightly increased, SUVmax=2.4.
Intestinal filling is unsatisfactory, with physiological uptake.
The cervix is full, with a slightly low-density mass visible, with indistinct borders and uneven density.
Calcifications are seen within, measuring approximately 5.1*4.3*3.3cm, with increased FDG uptake, SUVmax=13.1.
Multiple cystic lesions are also seen on the cervix, the largest being approximately 1.6cm in long diameter.
The uterus is full, with irregular edges and nodular elevations.
The myometrium has uneven density, and FDG uptake is increased, SUVmax=3.6.
Bilateral iliac lymph nodes are slightly enlarged, with a short diameter of approximately 1.0 cm, showing increased FDG uptake (SUVmax = 3.7).
Small retroperitoneal and bilateral inguinal lymph nodes are also observed, the largest being approximately 0.8 cm in short diameter; FDG metabolism is normal.
An irregular cystic mass is present in the left adnexal region, with relatively clear borders, measuring approximately 6.9*5.3*6.5 cm.
The cyst wall is unevenly thickened, with the thickest section measuring approximately 1.2 cm.
FDG uptake is slightly increased (SUVmax = 3.0).
No obvious abnormalities are seen in the right adnexal region.
The bladder is poorly filled, but no obvious positive stones are seen.
No obvious fluid accumulation is seen in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral body margin osteophytes and L5/S1 intervertebral disc bulging with posterior margin calcification.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Cervical mass with elevated FDG metabolism, highly suggestive of cervical cancer; please correlate with clinicopathology. Bilateral iliac lymph node metastasis to be ruled out; reactive hyperplasia of retroperitoneal and bilateral inguinal lymph nodes. b. Cystic mass in the left adnexal region, with uneven thickening of the cyst wall and slightly elevated FDG metabolism, suggestive of cyst or cystadenoma; please correlate with enhanced MRI. c. Possible adenomyosis with fibroids; Nabothian cyst of the cervix.

2. Ground-glass nodules in the apical-posterior segment of the left upper lobe, the lateral segment of the right middle lobe, and the posterior segment of the left lower lobe, suggestive of inflammation or atypical adenomatous hyperplasia; follow-up CT is recommended. A few post-inflammatory lesions in both lungs. Partial arteriosclerosis.

3. Bilateral breast hyperplasia. Reactive hyperplasia of bilateral axillary lymph nodes.

4. Mild fatty liver, cyst in the right lobe of the liver.

5. Partial chronic inflammatory changes in the gastric wall; please follow up with endoscopy.

6. Degenerative changes in the spine, L5/S1 intervertebral disc bulge with posterior calcification.

7. No obvious abnormalities were found 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.
