The left parotid gland and right submandibular gland were not clearly visualized, and FDG uptake was normal.
The right parotid gland and left submandibular gland showed normal size, shape, and density, and FDG uptake was physiological.
The thyroid gland was normal in shape and size, with no obvious abnormal density shadows, and FDG uptake was normal.
No obviously enlarged lymph nodes were seen in the bilateral deep cervical spaces, submandibular region, or submental region, and FDG uptake was normal.
A soft tissue nodule with a long diameter of approximately 0.8 cm was seen in the anterior segment of the left upper lobe, with clear borders, a lobulated appearance, and high density; FDG uptake was normal.
A few solid miliary foci were seen in the right upper lobe.
Increased translucency of both lungs with cystic lucent shadows, a few patchy and linear shadows in both lungs, and a few arc-shaped ground-glass opacities in the subpleural region of the posterior aspect of both lower lobes; FDG uptake was normal.
Slight pleural thickening was observed in some areas, but no obvious pleural effusion was seen in either pleural cavity.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions, and FDG uptake was not significantly increased.
The heart size was normal.
Calcification was observed in the walls of the aorta and its branches (including the coronary arteries).
The left lateral lobe of the liver was enlarged, the hepatic fissure was slightly widened, and the liver margins were not smooth.
Punctate high-density lesions were observed in the right lobe of the liver.
Multiple density nodules and masses with indistinct borders were observed in the right lobe and left medial lobe of the liver.
FDG uptake was increased near the lesion in the lower segment of the right posterior lobe of the liver (SUVmax = 2.9), with an uptake area of approximately 1.1 2.3 cm.
FDG uptake was decreased or absent in other lesions.
No dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was normal in shape and size, the gallbladder wall was not thickened, no positive stones or obvious masses were observed, and FDG uptake in the gallbladder fossa was normal.
The peripancreatic spaces are clear, with significant fatty infiltration in the head and neck of the pancreas.
No obvious abnormal density shadows are seen in the body and tail.
The pancreatic duct is not widened, and no abnormal FDG uptake is observed.
The spleen is generally normal in shape and size, with no abnormalities in density or FDG uptake.
Both adrenal glands are normal in shape, size, and density, with no abnormalities in local FDG uptake.
Both kidneys are normal in shape and size.
A small patchy slightly high-density shadow is seen in the upper part of the left kidney.
No obvious abnormal density shadows are seen in the right renal parenchyma, and no obvious abnormalities in FDG uptake are observed.
No widening of the renal pelvis, calyces, or ureters is observed bilaterally, and no positive stones are seen locally.
The prostate is normal in shape and size, with punctate calcifications seen internally.
No focal abnormal increases in FDG uptake are observed.
A small amount of hydrocele is present in the right testis.
Bladder distension is poor; no obvious localized thickening or mass is seen in the wall, and no positive stones are found in the lumen.
Esophageal dilatation is not seen; no obvious thickening or mass is seen in the esophagus wall; FDG uptake is increased in some parts of the esophagus wall, SUVmax=2.5.
Stomach is well distended; the mucosal folds on the greater curvature of the gastric body are thickened, and the gastric wall in the antrum is slightly thickened; FDG uptake is normal.
Intestinal distension is unsatisfactory; no local masses are seen; FDG uptake is increased in some parts of the intestine, SUVmax=3.1.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region; FDG uptake is normal.
No obvious effusion is seen in the abdominal cavity or pelvic cavity.
The spinal alignment is normal; some vertebral bodies show marginal osteophyte formation; a mass-like high-density lesion is seen in the L2 vertebral body; FDG uptake is decreased in the lower thoracic and lumbar vertebrae.
Two areas of increased FDG uptake were observed in the medullary cavity of the left proximal femur, with SUVmax = 2.7.
No obvious abnormalities were found in the left hip and left knee joints.
Physiological uptake was observed in some muscles of both lower limbs and feet.

Impression

1. a. Liver cirrhosis, partial iodized oil deposition after interventional treatment for liver cancer, multiple space-occupying lesions in the right lobe and left inner lobe of the liver, with increased FDG metabolism near the lesion in the lower segment of the right posterior lobe, suggesting possible residual tumor activity; the tumor activity in the remaining lesions is basically suppressed. Please compare with old films and follow up with enhanced MRI.? b. Two areas of increased FDG metabolism in the medullary cavity of the upper segment of the left femur, possibly metastatic tumors. Please follow up with enhanced MRI.? c. Post-L2 vertebral body cementation surgery, changes after radiotherapy to the lower thoracic and lumbar spine. Degenerative changes in the spine.

2. a. Lobulated soft tissue nodules in the anterior segment of the left upper lobe of the lung, no increased FDG metabolism, suggestive of induration. Please compare with old films and follow up with CT.? b. Chronic inflammatory miliary lesions in the upper lobe of the right lung. Bilateral emphysema with bullae, minor chronic inflammation and sequelae in both lungs, and lower lobe aspiration effect in both lungs. Partial arteriosclerosis (including coronary arteries).

3. Chronic inflammatory changes in the esophagus and stomach, and physiological or inflammatory uptake in some intestinal segments; endoscopic re-examination is necessary if required.

4. Fatty infiltration of the pancreas head and neck. Possible calcification in the left kidney. Calcification in the prostate. Small amount of hydrocele in the right testis.

5. No obvious abnormalities on cranial scintigraphy. Postoperative changes in the left parotid gland; the right submandibular gland is not clearly visualized; clinical correlation is required.

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.
