Whole-body 18F-FDG PET/CT scan in a patient with Lymphoma 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 scan showed: a small patchy, slightly low-density shadow near the posterior horn of the right lateral ventricle; punctate low-density shadows in the deep brain regions bilaterally; no significant abnormalities in FDG metabolism.
Widening of local sulci and fissures, but no abnormalities in local density or FDG uptake; no midline shift.
No significant abnormalities in the skull bone; no increased FDG uptake.
No abnormalities in the shape and outline of the bilateral eyeballs; clear retrobulbar structures; symmetrical optic nerves bilaterally; no abnormal FDG uptake.
Thickening of the left sphenoid sinus mucosa; no abnormalities in FDG uptake.
No thickening of the nasopharyngeal wall; no abnormalities in FDG uptake.
No abnormalities in the shape and structure of the laryngopharynx; clear parapharyngeal space.
No abnormalities in the size, shape, or density of the bilateral submandibular and parotid glands; physiological FDG uptake.
Focal increase in FDG uptake in the right inferior alveolar region; SUVmax = 4.9.
The density of the thyroid gland is uneven between the left and right lobes, with slightly increased FDG uptake (SUVmax = 2.6).
Partial calcification is present in the bilateral carotid artery walls.
Multiple lymph nodes are visible bilaterally above the clavicle, in the left hilum, at the thoracic inlet, behind the vena cava, para-aortic arch, at the aortic window, and below the carina, some with internal calcification.
The largest, approximately 3.8*3.1cm, is located below the carina and shows increased FDG uptake (SUVmax = 16.5).
The thorax is symmetrical bilaterally, with increased lung markings.
Multiple cystic lucent shadows are seen in the upper lobes of both lungs and the basal segment of the right lower lobe.
One air-filled cystic cavity in the posterior segment of the right lower lobe, adjacent to the spine, has a thicker wall and rougher edges; no increased FDG uptake is observed.
Multiple calcified nodules and linear shadows are seen in the posterior segment of the right lower lobe, with slight local thickening of the bronchial wall; no significant abnormalities in FDG metabolism are observed.
Scattered linear shadows are seen in both lungs.
Multiple small, patchy, slightly high-density shadows were observed in the subpleural region of the right middle lobe and left upper and lower lobes, with relatively clear borders.
The largest shadow, measuring approximately 2.3*1.7 cm, was found in the left lower lobe.
Some shadows showed slightly increased FDG uptake, with an SUVmax of 1.7.
Bilateral pleural thickening was observed, but there was no pleural effusion.
FDG uptake was normal.
Partial aortic wall calcification was present.
The heart shadow was within the normal size range, with pericardial thickening and a small amount of effusion.
The cardiac chamber density was lower than that of the myocardium.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Calcification was observed in the right lobe of the liver, and FDG metabolism was normal.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall, no positive stones or obvious masses, and a clear gallbladder fossa.
Local FDG uptake was normal.
The pancreatic parenchyma showed slight atrophy, with no obvious abnormal density shadows, clear surrounding spaces, no widening of the pancreatic duct, and no abnormal FDG uptake.
The spleen is generally normal in shape and size, with punctate calcifications visible within; FDG uptake is normal.
Both kidneys are normal in shape and size, with no localized protrusions at the renal margins.
Plain CT scan shows no obvious abnormal density shadows within the parenchyma; FDG uptake is normal.
Both adrenal glands are normal in shape, size, and density; local FDG uptake is normal.
The lower esophagus, cardia, and antrum show slight thickening of the gastric wall, with increased FDG uptake (SUVmax = 3.5).
Continuous increased FDG uptake is observed in parts of the colon and rectum (SUVmax = 12.6).
Increased FDG uptake is observed at the anal orifice (SUVmax = 8.4).
Extensive calcification is present in the walls of the abdominal aorta and bilateral iliac arteries; the abdominal aorta is locally thickened.
The prostate is of normal volume, with a long diameter of approximately 4.2 cm; parenchymal FDG uptake is unevenly increased (SUVmax = 4.7).
The bladder is poorly filled; no positive stones or obvious masses are observed locally.
Postoperative lumbar tumor surgery, T12-L2 vertebral fixation is underway, with significant surrounding metal artifacts and unclear detail visualization.
FDG metabolism is normal.
Systemic bone density is decreased, and osteophytes are present in various vertebrae.
Multiple intervertebral disc bulges with pneumothorax and degeneration are present.
A small patch of increased FDG uptake is observed at the left sacroiliac joint (SUVmax = 2.9).

Impression

1. Newly observed multiple enlarged lymph nodes bilaterally in the supraclavicular fossa, left hilum, and mediastinum, accompanied by increased FDG metabolism, suggestive of a neoplastic lesion (most likely lymphoma). Other lymphocytic proliferative diseases need to be ruled out; please correlate with clinicopathology.

2. Small patchy slightly low-density lesion adjacent to the posterior horn of the right lateral ventricle, and punctate low-density lesions in the deep brain regions bilaterally, neither showing significant mass effect. FDG metabolism was not significantly abnormal, suggesting possible ischemic lesions. Please combine clinical findings with enhanced MRI for comprehensive judgment. Age-related brain changes.

3. a. Multiple bullae in the upper lobes of both lungs and the lower lobe of the right lung. Among them, one bulla in the posterior segment of the right lower lobe adjacent to the spine has shrunk compared to the previous examination, with thickened and roughened walls. FDG metabolism was not abnormal, suggesting a high probability of concurrent infection. Please follow up with CT. b. Old lesions in the posterior segment of the right lower lobe, fibrotic lesions in both lungs, and newly observed scattered subpleural inflammation in the right middle lobe and the upper and lower lobes of the left lung. CT follow-up is recommended after anti-infective treatment. Bilateral pleural thickening. Pericardial thickening with a small amount of effusion. Anemia.

4. Liver calcifications. Splenic calcifications. Multiple arteriosclerosis throughout the body.

5. Possible chronic inflammation of the lower esophagus, part of the stomach wall, and intestines; please combine with endoscopic examination. Hemorrhoids.

6. Mildly elevated FDG metabolism in the prostatic parenchyma, suggesting possible chronic prostatitis; please combine with PSA follow-up.

7. Osteoporosis, degenerative changes in the cervical, thoracic, and lumbar spine. Multiple intervertebral disc bulges with pneumoconiosis. Left sacroiliitis. Postoperative changes at T12-L2 vertebral bodies.

8. Uneven density in the left and right lobes of the thyroid gland, with mild FDG uptake, highly suggestive of chronic thyroiditis; please combine with ultrasound follow-up. Chronic inflammation of the left sphenoid sinus. Right inferior alveolar ulceritis.

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.
