Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed: A slightly high-density nodule, approximately 0.9 cm in long diameter, was seen in the right parietal lobe, with increased FDG metabolism (SUVmax = 11.5); a surrounding edema zone was observed.
Localized decreased density was observed in the left temporal lobe, with no significant abnormalities in FDG uptake.
Widening of the sulci and gyri was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
Thickening of the maxillary sinus mucosa was observed bilaterally, with intact sinus walls.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, with no stenosis of the Eustachian tube openings.
The infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size, with slightly heterogeneous density; FDG uptake is normal.
An irregular mass measuring approximately 3.8 4.0 cm is seen near the hilum in the right upper lobe, with increased FDG metabolism (SUVmax = 11.8), corresponding bronchial obstruction, and multiple punctate and patchy shadows around the mass, with increased FDG metabolism (SUVmax = 4.5).
Multiple round or oval solid nodules are seen in both lungs, the largest being approximately 1.1 cm in length in the posterior basal segment of the right lower lobe, with clear borders; some have increased FDG metabolism (SUVmax = 2.9).
Multiple ground-glass nodules are seen in both lungs, some with indistinct borders; the largest being approximately 1.0 cm in length in the anterior basal segment of the right lower lobe, with a maximum CT value of approximately -440 HU; FDG uptake is normal.
Thickening of the interlobular septa in both lungs, with diffuse reticular changes; scattered patchy hazy shadows and high-density shadows in both lungs; increased FDG metabolism, SUVmax=3.5.
Small amount of pleural effusion bilaterally.
Multiple enlarged lymph nodes were observed in the bilateral hilar regions, great vessel spaces, pretracheal spaces, para-aortic arch, aortopulmonary window, subcarinal region, right cardiophrenic angle, bilateral supraclavicular fossa, and left posterior cervical triangle; the largest had a short diameter of approximately 1.2 cm; increased FDG metabolism, SUVmax=11.2.
No abnormalities were observed in the cardiac silhouette.
Small amount of pericardial effusion; partial calcification of arterial walls (including coronary arteries).
No esophageal dilatation, significant wall thickening or mass was observed; no increased FDG uptake was observed.
The liver showed no significant abnormalities in shape or size; the liver margins were smooth; the hepatic fissures were not widened; no significant abnormal density shadows were observed in the liver parenchyma on plain CT scan; no abnormal FDG uptake was observed.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall and no abnormalities in local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen was normal in shape, size, density, and FDG uptake.
Cystic lesions were observed in both kidneys, approximately 1.0 cm in long diameter, with absent FDG uptake.
No widening was observed in the renal pelvis, calyces, or ureters; a patchy dense shadow was observed in the left renal calyx.
The left adrenal gland was slightly enlarged, with increased FDG uptake (SUVmax = 4.0).
The stomach was poorly distended, with no significant thickening of the stomach wall and no obvious abnormalities in FDG uptake.
The intestines were poorly distended, with increased FDG metabolism in some parts of the intestine (SUVmax = 4.7).
The prostate is normal in size and shape, with uniform density, and no abnormal FDG metabolism was observed.
The bladder is generally full, and no obvious positive stones were seen within it.
No enlarged lymph nodes were seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious effusion was seen in the abdominal or pelvic cavities.
The S1 vertebral body is lumbarized.
The L2 vertebral body is slightly displaced, and the L1 vertebral body shows significant lesions with osteophyte formation at the margins of some vertebral bodies.
There is bulging of the L4/5 and L5/S1 intervertebral discs.
Multiple ribs, multiple vertebral bodies and their appendages, the sacrum, and bilateral iliac bones show bone destruction, with increased FDG metabolism (SUVmax = 8.39).
The right abdominal wall muscles are swollen, with increased FDG uptake (SUVmax = 5.3).
A solid nodule with a long diameter of approximately 0.9 cm was seen subcutaneously in the right mid-abdomen, with increased FDG uptake (SUVmax = 5.1).

Impression

1. a. A mass in the right upper lobe of the lung with elevated FDG metabolism, suggestive of lung cancer, possibly accompanied by carcinomatous lymphangitis. Please confirm the diagnosis with pathological examination. b. Multiple lymph node metastases in the bilateral hilar, mediastinal, right cardiophrenic angle, bilateral supraclavicular fossa, and left posterior cervical triangle. c. Multiple bone metastases throughout the body. Left adrenal metastasis to be ruled out. Possible subcutaneous metastasis in the right mid-abdomen. d. Multiple solid nodules in both lungs, some with elevated FDG metabolism, suggestive of chronic inflammatory nodules, some metastases to be ruled out. Multiple ground-glass nodules in both lungs with normal FDG metabolism, suggestive of chronic inflammatory nodules or atypical adenomatous hyperplasia. Regular HRCT follow-up is recommended for all of the above. e. Interstitial changes in both lungs with scattered inflammation and remnants. CT follow-up after anti-inflammatory treatment is recommended to rule out other occult lesions. Bilateral pleural effusion. Calcification of some arterial walls (including coronary arteries). Small amount of pericardial effusion.

2. Slightly high-density nodule in the right parietal lobe, with increased FDG metabolism, suggesting a high probability of metastasis; localized decreased density in the left temporal lobe, metastasis to be ruled out. MRI with contrast enhancement is recommended for confirmation. Age-related brain.

3. Bilateral renal cysts. Left renal calculus.

4. Increased FDG metabolism in some intestinal segments, considering inflammatory or physiological uptake; colonoscopy is recommended.

5. Degenerative changes in the spine. L2 vertebral instability. L1 vertebral wedging. L4/5, L5/S1 intervertebral disc bulging. Right abdominal wall muscle swelling with increased FDG metabolism, suggesting possible inflammatory changes; follow-up is needed to rule out other possibilities.

6. Bilateral chronic maxillary sinusitis.

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.
