Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed with both hands raised, from the top of the skull to the upper thigh: The brain morphology and structure were normal, with punctate and nodular slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
Both eyeballs were symmetrical, with no obvious abnormalities.
The bilateral ethmoid sinus mucosa was slightly thickened, while the mucosa of the remaining paranasal sinuses was not thickened, and the sinus walls were intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear; FDG uptake was normal.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx were normal in morphology and structure.
The thyroid gland was normal in morphology and size, with slightly uneven density; FDG uptake was normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Increased lung markings were present bilaterally, with several ground-glass nodules, the largest located in the anterior segment of the left upper lobe, with indistinct borders, approximately 0.5 cm in length, and a mean CT value of -482 HU.
FDG uptake was normal.
Multiple solid nodules were observed bilaterally, with well-defined borders, the largest approximately 0.4 cm in diameter.
FDG uptake was normal.
Slight bronchial dilatation with surrounding patchy shadows was observed in the lower lingular segment of the left upper lobe.
Scattered linear lesions were observed bilaterally, with normal FDG uptake.
Partial pleural thickening was observed bilaterally, without pleural effusion or pneumothorax.
A cystic opacity containing air was observed at the right posterior margin of the upper trachea.
No significantly enlarged lymph nodes were observed bilaterally in the hilum or mediastinum.
The cardiac silhouette was normal.
The cardiac chamber density was slightly lower than that of the myocardium, with partial calcification of the arterial walls (including the coronary arteries).
Small nodules were observed bilaterally, the largest located in the lateral part of the left breast, approximately 0.7 cm in diameter.
Calcification was also observed in the right breast.
FDG metabolism was normal.
No esophageal dilation, wall thickening, or mass was observed; FDG uptake was not increased.
An irregular low-density mass with indistinct borders and uneven density was found in the right posterior lobe of the liver, with a CT value of approximately 36 HU and a size of approximately 8.9cm 7.3cm 8.2cm; FDG uptake was increased, SUVmax = 11.1.
A slightly low-density mass with indistinct borders was found in the left medial lobe of the liver, with a CT value of approximately 48 HU and a size of approximately 3.1cm 3.0cm; FDG uptake was increased, SUVmax = 4.5.
The liver's shape and size were normal; the liver margins were smooth; the hepatic fissure was not widened.
A dense nodule with a diameter of approximately 0.4cm was found in the right anterior lobe of the liver; the remaining liver tissue showed uneven density, but FDG uptake was normal.
An enlarged lymph node measuring approximately 2.3cm 1.6cm was found adjacent to the inferior vena cava in the upper abdomen; FDG uptake was increased, SUVmax = 8.5.
The remaining retroperitoneal lymph nodes showed a maximum short diameter of approximately 0.6 cm, with increased FDG uptake (SUVmax = 2.6).
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall and no abnormal FDG uptake in the affected area.
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 abnormal FDG uptake.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormal FDG uptake.
The left adrenal gland was thickened with increased FDG uptake (SUVmax = 3.0); the right adrenal gland showed no obvious abnormalities on contrast.
The stomach was poorly filled, with slight thickening of the walls of the cardia, part of the gastric body, and antrum, and mildly increased FDG uptake (SUVmax = 2.7).
The intestines were poorly filled, with no obvious space-occupying lesions, but some intestinal segments showed increased FDG uptake (SUVmax = 3.7).
The uterus is normal in shape and size, with no abnormal density shadows, and FDG uptake is normal.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly filled, but no obvious positive stones are seen.
Overall bone density is decreased; the spinal alignment is normal, with some vertebral body margin osteophytes, and L4/5 and L5/S1 intervertebral disc bulging with pneumoconiosis and degeneration.
FDG uptake of all bones is normal.

Impression

1. Two liver lesions with elevated FDG metabolism, suggestive of malignancy, hepatocellular carcinoma is the primary consideration, cholangiocarcinoma to be ruled out. Please combine tumor markers and enhanced MRI for comprehensive analysis. Metastasis to the right para-inferior vena cava lymph nodes in the upper abdomen. Reactive hyperplasia of the remaining retroperitoneal lymph nodes.

2. a. Several ground-glass nodules in both lungs, FDG metabolism normal, suggest inflammation or atypical adenomatous hyperplasia, CT follow-up recommended. b. Chronic inflammatory micronodules (solid) in both lungs, CT follow-up recommended. Slight bronchial dilatation with chronic inflammation in the lower lingular segment of the left upper lobe, a few post-inflammatory remnants in both lungs. Partial pleural thickening bilaterally. Tracheal diverticulum. Mild anemia changes, partial calcification of arterial walls (including coronary arteries).

3. Small nodules in both breasts, FDG metabolism normal, suggest fibroadenoma or hyperplastic nodules, calcification in the right breast, ultrasound follow-up recommended.

4. Calcification in the right lobe of the liver. Left adrenal hyperplasia.

5. Chronic inflammatory changes or physiological metabolic changes in parts of the stomach wall and intestines; please follow up with endoscopy.

6. Osteoporosis, degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge with pneumoconiosis and degeneration.

7. Age-related brain changes, deep lacunar infarcts in the brain, and formation of some small softening lesions. Bilateral chronic ethmoid 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.
