Whole-body 18F-FDG PET/CT scan in a patient with Lung 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: Normal brain morphology and structure; a soft tissue mass in the left frontal lobe, approximately 3.1*2.8cm in size, with increased FDG uptake (SUVmax = 14.5); patchy low-density shadows were seen in the surrounding brain parenchyma; compression of the anterior horn of the left ventricle; and slight rightward deviation of the midline.
No widening was observed in the remaining ventricles, sulci, fissures, or cisterns; both ventricles were symmetrical.
Both eyeballs were symmetrical and showed no obvious abnormalities.
Thickening of the mucosa of the bilateral ethmoid and maxillary sinuses was observed, but no thickening was seen in the mucosa of the remaining paranasal sinuses; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; both palatine tonsils were symmetrical, and FDG uptake was physiological.
The morphology and structure of the laryngopharynx were normal.
The bilateral parotid and submandibular glands had normal morphology and density, and FDG uptake was physiological.
The thyroid gland is normal in shape and size, but its density is somewhat heterogeneous.
Several low-density nodules are present in both lobes, with calcification on the right side.
The largest nodule measures approximately 1.2 cm in length.
Some nodules show increased FDG uptake, with an SUVmax of 6.3.
There is stenosis/occlusion of the bronchus in the posterior segment of the left lower lobe, accompanied by soft tissue nodule formation, measuring approximately 2.6*2.6 cm.
FDG uptake is increased, with an SUVmax of 10.0.
An irregular subpleural nodule, approximately 1.3*1.1 cm in size, is present in the posterior basal segment of the left lower lobe, with lobulated margins and small vacuoles.
FDG uptake is increased, with an SUVmax of 4.5.
Multiple small solid nodules are present in both lungs, with well-defined borders.
The largest nodule is located in the inferior lingular segment of the left upper lobe, measuring approximately 0.6 cm in diameter.
FDG uptake is slightly increased, with an SUVmax of 2.0.
Multiple patchy and linear lesions are present in both lungs, with no abnormalities in FDG uptake.
The left pleura is thickened.
The left hilum, pretracheal vena cava, aortic window, para-aortic arch, subcarinal, bilateral supraclavicular fossa, bilateral posterior cervical triangle, bilateral deep cervical space, right submandibular region, and retroperitoneal lymph nodes are visible.
The largest is located in the left hilum, with a short diameter of approximately 3.1 cm.
FDG uptake is increased, with an SUVmax of 12.1.
Pericardial thickening with effusion is present.
Some arteries show slight sclerosis.
The esophagus is not dilated, and the wall is not significantly thickened or swollen.
FDG uptake is not increased.
Both breasts are densely packed with glandular tissue, without obvious masses or nodules.
FDG metabolism is not significantly abnormal.
The liver is normal in shape and size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan shows no abnormal density shadows in the liver parenchyma, and FDG uptake is normal.
The main portal vein is not significantly widened, and there is no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
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 not significantly abnormal.
The spleen is normal in shape, size, density, and FDG uptake.
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 not significantly abnormal.
Both adrenal glands are thickened with soft tissue nodules, the right one being larger, with a long diameter of approximately 1.7 cm, and increased FDG uptake (SUVmax = 8.4).
The stomach is adequately filled, with slight thickening of the gastric wall in the cardia and antrum, and slightly increased FDG uptake (SUVmax = 3.0).
The intestines are not sufficiently filled, with no local masses, and FDG uptake is not abnormal.
The cervix is full, with a low-density lesion of approximately 1.4 cm in long diameter visible.
No other abnormal density shadows are seen in the uterus, and FDG metabolism is not abnormal.
A low-density mass measuring approximately 5.2*3.6cm was observed in the left adnexal region, with increased FDG uptake at the periphery (SUVmax=4.9).
No abnormalities were observed in internal FDG metabolism.
The bladder was poorly filled, but no obvious positive stones were seen.
The spinal alignment was normal, with mild osteophyte formation at the margins of some vertebral bodies.
A high-density lesion, approximately 1.1cm in diameter, was observed in the left iliac bone, with no abnormalities in FDG metabolism.
Multiple lesions with increased FDG uptake were found in the right pedicle of T7, the left pedicle of L5, and the spinous process (SUVmax=12.0).

Impression

1. a. A mass in the posterior segment of the left lower lobe with increased FDG uptake, suggestive of lung cancer. An irregular nodular lesion in the posterior basal segment of the left lower lobe with increased FDG metabolism, suggestive of possible lung cancer. b. Multiple metastases in both lungs. Multiple lymph node metastases in the left hilum, mediastinum, bilateral supraclavicular fossa, bilateral neck, and retroperitoneum. c. Metastasis in the left frontal lobe. Metastases in the T7 and L5 adnexa. Bilateral adrenal metastases.

2. Chronic inflammation and post-inflammatory remnants in both lungs. Left pleural thickening, pericardial thickening with effusion. Minor arteriosclerosis in some arteries.

3. A low-density mass in the left adnexal region with locally increased FDG metabolism at the periphery, suggestive of ovarian neoplastic lesions or cysts; please combine with enhanced MRI for comprehensive analysis. Nabothian cysts of the cervix.

4. Low-density nodules in both lobes of the thyroid gland, with calcification on the right side and increased FDG uptake in some areas, suggestive of possible nodular goiter; malignancy in some areas needs to be ruled out; ultrasound follow-up is recommended.

5. Chronic inflammatory changes in the cardia and antrum of the stomach.

6. Mild osteophyte formation in the spine, with a bony island in the left iliac bone.

7. Chronic inflammation of both ethmoid and maxillary sinuses.

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.
