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, with punctate low-density lesions in the deep bilateral cerebral regions; no significant abnormalities in FDG metabolism.
Enlargement of the ventricles, sulci, fissures, and cisterns; symmetrical bilateral ventricles; no midline shift.
Normal bilateral eyeball morphology and contour; clear retrobulbar structures; symmetrical bilateral optic nerves; no abnormal FDG metabolism.
Slight thickening of the mucosa in the right maxillary sinus; intact sinus wall; absent FDG metabolism.
No thickening of the nasopharyngeal wall; no stenosis of the bilateral pharyngeal recesses and Eustachian tube openings; normal structures of the infratemporal fossa and pterygopalatine fossa; clear bilateral parapharyngeal spaces; no abnormal FDG metabolism.
Physiological FDG metabolism in the oropharynx and laryngopharynx.
No abnormal contrast enhancement of the bilateral parotid and submandibular glands.
No significant development of the right mastoid air cells.
The thyroid gland is normal in shape and size, with uniform density, and no abnormalities were observed in FDG metabolism.
Lymph nodes are visible in the right deep cervical space and bilateral supraclavicular fossa, the largest measuring approximately 2.4 cm in short diameter, with increased FDG metabolism (SUVmax = 8.0).
Increased and disordered pulmonary edema is observed in both lungs.
A soft tissue mass measuring approximately 3.7*4.3 cm is seen in the apical segment of the right upper lobe near the hilum, with increased FDG metabolism (SUVmax = 12.9), and corresponding bronchial compression and stenosis.
Several small solid nodules with clear margins and relatively uniform internal density are seen in the apical segment of the right upper lobe and the posterior segment of the left lower lobe, the largest measuring approximately 0.9 cm in long diameter, with increased FDG metabolism (SUVmax = 3.9).
Scattered small solid nodules in both lungs are regular in shape, with clear borders, and a long diameter of approximately 0.3-0.4 cm; no abnormalities were observed in FDG uptake.
A few linear opacities and calcifications were observed in both lungs, with no abnormalities in FDG metabolism.
Small cystic lucent shadows were seen in the subpleural region of both upper lobes.
The pleura was slightly thickened bilaterally, but there was no pleural effusion or pneumothorax.
Lymph nodes were visualized in the hilar and mediastinal regions (right superior mediastinal inlet, anterior superior mediastinal space, posterior to the trachea and vena cava, aortic window, subcarinal region, and cardiophrenic angle), with the largest located in the right hilum, approximately 1.8 cm in short diameter, showing increased FDG metabolism (SUVmax = 9.6).
The cardiac silhouette was normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The liver was enlarged with smooth margins, and the hepatic fissure was not widened.
Diffuse masses and nodules of varying sizes were observed within the liver, with unevenly increased FDG metabolism (SUVmax = 15.6).
Several cystic lesions with smooth margins were also seen in the liver parenchyma, the largest approximately 1.0 cm in long diameter, with absent FDG metabolism.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was reduced in size, with slightly thickened and roughened walls; a fluid density shadow was seen in the gallbladder fossa, and local FDG metabolism was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG metabolism was normal.
The spleen was normal in shape, size, density, and FDG metabolism.
Both kidneys were normal in shape and size; cystic low-density lesions were seen in the parenchyma of both kidneys, with clear borders; the largest lesion had a long diameter of approximately 3.3 cm, with calcifications seen in the right part of the cyst wall; FDG metabolism was absent.
The renal pelvis, calyces, and ureters were not widened, and FDG metabolism was normal.
Bilateral adrenal gland contrast was normal.
The esophagus was not dilated, and no significant thickening or mass was seen in the esophageal wall; FDG metabolism was not increased.
The stomach is generally full, with no obvious thickening of the stomach wall, and no obvious abnormalities in FDG metabolism.
The intestines are poorly full, with increased FDG metabolism in parts of the colon and rectum (SUVmax = 3.5).
The prostate is enlarged, with a transverse diameter of approximately 4.9 cm; no obvious abnormal density shadows are seen in the parenchyma, and FDG metabolism is normal.
The bladder is poorly full, with no obvious positive stones.
Fluid density shadows are present in both scrotums, but FDG metabolism is absent.
Multiple lymph nodes are visible in the prediaphragmatic group, hepatogastric space, porta hepatis, and around the pancreas, the largest measuring approximately 2.7*2.2 cm, with increased FDG metabolism (SUVmax = 12.1).
Hyperplasia of the paracolic mesentery is present on both sides, with increased FDG metabolism (SUVmax = 3.2).
Significant fluid accumulation is present in the abdomen and pelvis.
The spinal alignment is normal, with calcification of the nuchal ligament and osteophyte formation at the margins of some vertebral bodies.
L3/4, L4/5, and L5/S1 intervertebral disc bulging with pneumoconiosis and degeneration, with no abnormal FDG metabolism.
Increased FDG metabolism was observed in multiple sites of bilateral scapula, sternum, some ribs, some vertebral bodies, sacrum, pelvis, and bilateral femoral medullary canals, with SUVmax=10.4.

Impression

1. a. A mass near the hilum in the apical segment of the right upper lobe, with elevated FDG metabolism, strongly suggestive of central lung cancer; please corroborate clinicopathology. Multiple lymph node metastases in bilateral hilar regions, mediastinum, prediaphragmatic group, hepatogastric space, hepatic hilum, peripancreatic region, bilateral supraclavicular fossa, and right deep cervical space. Nodular metastases in the apical segment of the right upper lobe and the posterior segment of the left lower lobe. Multiple bone metastases throughout the body. b. Mesenteric proliferation in the left and right paracolic gutter, with elevated FDG metabolism, suggesting possible metastasis. Significant effusion in the abdomen and pelvis. c. Diffuse lesions in the liver, with unevenly elevated FDG metabolism, suggestive of malignancy, with a higher probability of metastasis than the primary tumor. Liver cysts.

2. Chronic bronchitis and emphysematous changes in both lungs. Scattered small chronic inflammatory nodules (solid) in the remaining lungs; please follow up with CT scans. A few post-inflammatory remnants and calcifications in both lungs. Mild thickening of the pleura bilaterally. Partial arteriosclerosis (including coronary arteries).

3. Chronic cholecystitis. Bilateral renal cysts, with the right kidney showing a complex cyst. Benign prostatic hyperplasia. Bilateral hydrocele.

4. Increased FDG metabolism in parts of the colon and rectum, considered physiological uptake or chronic inflammatory changes; please follow up with endoscopy.

5. Degenerative changes in the spine. L3/4, L4/5, and L5/S1 intervertebral disc bulging with pneumoconiosis and degeneration.

6. Age-related brain changes, deep lacunar infarcts in the brain; MRI is recommended. Minor inflammation of the right maxillary sinus. Right sclerotic mastoid process.

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.
