There are nodules and patchy thickenings in the left pleura accompanied by increased FDG uptake (SUVmax=5.7), and left-sided pleural effusion.
A mixed ground-glass opacity lesion in the subpleural region of the apical segment of the right upper lobe has indistinct borders and spiculated margins, with pleural traction, measuring approximately 1.6*1.7cm, and increased FDG uptake (SUVmax=3.0).
Multiple solid nodules and plaque-like lesions are present in both lungs, the largest located in the lateral basal segment of the right lower lobe, with indistinct borders and a diameter of approximately 1.0cm, showing slightly increased FDG uptake (SUVmax=2.3).
Scattered patchy and linear lesions are present in both lungs, with no abnormal FDG uptake.
Multiple enlarged lymph nodes were observed in the bilateral hilar regions, pretracheal space, para-aortic arch, aortopulmonary window, subcarinal region, and bilateral supraclavicular fossa.
The largest lymph node had a short diameter of approximately 2.2 cm, with increased FDG uptake (SUVmax = 8.0).
Patchy soft tissue density shadows were observed in the pericardium, measuring approximately 3.4*2.5*4.0 cm, with increased FDG uptake (SUVmax = 11.0), and pericardial effusion was present.
The density of the cardiac chambers was lower than that of the myocardium.
No abnormal density shadows were observed in the bilateral breasts, and FDG metabolism was normal.
No esophageal dilation, significant wall thickening, or masses were observed, and FDG uptake was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Low-density lesions were observed in the right lobe near the diaphragm and the left medial lobe, with the largest measuring approximately 2.2 cm in diameter, showing increased FDG uptake (SUVmax = 10.7).
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, but the gallbladder wall was thickened, and patchy high-density shadows were seen within the gallbladder; local FDG uptake 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 uptake was normal.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size; a small cystic lesion was observed in the parenchyma of the left kidney, the largest being approximately 0.5 cm in diameter; FDG metabolism was normal.
High-density shadows were seen in the renal pelvis, calyces, ureters, and bladder; FDG uptake was normal.
Bilateral adrenal soft tissue shadows were observed, the largest measuring approximately 2.2*1.3 cm; FDG uptake was increased, with SUVmax = 8.9.
The stomach is poorly filled, with a significant amount of residual contents.
The antral wall is slightly thickened, and FDG uptake is mildly increased (SUVmax = 2.2).
Following cervical cancer treatment, the cervix is full and unevenly dense, with no abnormal FDG metabolism observed.
No obvious abnormal density shadows were seen in the remaining uterus.
Multiple foci of increased FDG metabolism were observed in the greater omentum and mesentery, with SUVmax = 7.8.
The largest uptake foci are approximately 1.6 cm in diameter, and some have unclear boundaries with the intestines.
No obvious pelvic effusion was observed.
A cystic lesion with clear borders, measuring approximately 2.1*1.8 cm, was found in the left adnexa, with absent FDG uptake.
No obvious abnormalities were observed in the right adnexa.
Right elbow, left clavicle, right scapula, right 7th and 8th ribs, multiple ribs on the left, multiple vertebral bodies and appendages of the spine, and multiple bone destructions in the left femoral head, most notably in the L1 vertebral body, with increased FDG uptake (SUVmax = 10.3).
Nodules in the soft tissue muscles of the left buttock and left shoulder, the largest approximately 1.7 cm in diameter, with increased FDG uptake (SUVmax = 9.4).
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, multiple intervertebral disc bulges, and an L3/4 disc herniation.
Decreased FDG metabolism is observed in some areas of the lumbosacral spine.
A nodular mixed-density shadow with sclerotic borders is present in the upper segment of the right femur; FDG uptake is normal.

Impression

1. a. A mass in the left upper lobe of the lung with increased FDG metabolism, suggestive of lung cancer; please refer to pathology. b. Metastatic lesions in the left pleura and pericardium, multiple lymph node metastases in the bilateral hilar, mediastinal, and bilateral supraclavicular fossae. c. Liver metastases. Bilateral adrenal metastases. d. Multiple bone metastases throughout the body (see description for details), muscle metastases in the left buttock and left shoulder. e. Suspected soft tissue nodule in the left parietal lobe, with background FDG uptake; metastasis to be ruled out; MRI is recommended.

2. a. After cervical cancer treatment, the cervical density is uneven, but FDG metabolism is normal, suggesting suppressed tumor activity after treatment. b. Multiple foci of increased FDG metabolism in the greater omentum and mesenteric region; metastasis to be ruled out; close observation is recommended.

3. a. Mixed ground-glass opacity in the subpleural region of the apical segment of the right upper lobe with increased FDG metabolism, suggestive of lung cancer; please correlate with clinicopathology. b. Possible chronic inflammatory nodules in both lungs; follow-up CT is recommended. Scattered post-inflammatory lesions in both lungs. Left pleural and pericardial effusion. Anemia.

4. Chronic cholecystitis, gallstones, or residual contrast agent. Residual contrast agent in the urinary tract. Left renal cyst. Left adnexal cyst. No obvious pelvic effusion.

5. Chronic inflammatory changes in the antrum of the stomach; please correlate with endoscopic follow-up.

6. Degenerative changes in the spine, multiple intervertebral disc bulges, L3/4 disc herniation. Post-radiotherapy changes in some lumbar and sacral vertebrae. Benign bone disease in the upper right femur.

7. 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.
