Mild bronchial dilatation was observed in both lower lobes.
Mild pleural thickening was observed bilaterally, with no pleural effusion or pneumothorax.
Multiple lymph nodes were observed bilaterally in the hilum, posterior to the vena cava, at the aortic window, and below the carina, the largest with a short diameter of approximately 1.0 cm.
FDG uptake was increased, with an SUVmax of 16.4.
The cardiac silhouette was normal, with a small amount of pericardial effusion.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was not increased.
Both breasts appeared normal, with no abnormal density shadows and normal FDG uptake.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissure.
Multiple low-density nodules and masses were observed in the liver parenchyma, some of which were fused together with indistinct borders.
The largest measured approximately 4.8*3.9cm, with increased FDG uptake (SUVmax = 27.0).
No significant widening of the main portal vein was observed, and no dilation of intrahepatic or extrahepatic bile ducts was seen.
Several enlarged lymph nodes were observed in the porta hepatis and hilar space, the largest with a short diameter of approximately 0.9cm, showing increased FDG uptake (SUVmax = 31.6).
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall, no positive stones or obvious masses, and no abnormal 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 abnormal FDG uptake.
The spleen was normal in shape and size, with no abnormal density or FDG uptake.
Both kidneys were normal in shape and size; a cystic lesion with a long diameter of approximately 0.7cm was observed in the left kidney, with no significant abnormal FDG uptake.
No widening of the renal pelvis, calyces, or ureters was observed bilaterally, and no positive stones were seen within them.
The bilateral adrenal glands showed no abnormalities in morphology or density, and local FDG uptake was normal.
Gastric distension was poor, but FDG uptake was not significantly abnormal.
Bowel preparation was poor, with no obvious masses in the intestinal wall, and FDG uptake was physiological.
FDG uptake in the anal region was increased, with SUVmax = 6.6.
The uterus was slightly full, with uneven density and uneven FDG uptake.
No abnormal density or FDG uptake was observed bilaterally in the adnexa.
Bladder distension was poor, with no positive stones or obvious masses seen within.
No significant fluid accumulation was observed in the abdomen or pelvis.
Scoliosis was present, with mild anterior displacement of the L5 vertebral body.
Osteophyte formation was observed at the marginal edges of some vertebral bodies.
Patchy high-density shadows were seen at the relative edges of the L3 and L4 vertebral bodies.
L3/4 and L4/5 intervertebral disc bulging with pneumothorax was observed.
Localized increased density and increased FDG uptake were observed in the right 5th rib, with SUVmax = 2.3.
Nodular high-density shadows were seen on the 3rd and 8th ribs on the right side.

Impression

1. After treatment of the left lung mass, combined with PET/CT images from another hospital: a. The mass in the anterior basal segment of the left lower lobe has shrunk compared to before, and FDG metabolism has not increased, suggesting that tumor activity has been suppressed after treatment. b. Partially shrunk lymph nodes in the bilateral hilar, mediastinal, right supraclavicular, hepatic hilum, and hilar space, with increased FDG metabolism, suggesting that tumor activity has been partially suppressed after treatment, with some still remaining. c. The liver metastases show significant activity; please follow up with enhanced MRI.

2. a. Mixed ground-glass nodules in the anterior basal segment of the right lower lobe, with normal FDG metabolism; malignancy cannot be ruled out. Please compare with the previous images and repeat HRCT after anti-inflammatory treatment. b. Ground-glass nodules in the apical-posterior segment of the left upper lobe and the posterior segment of the right upper lobe, with normal FDG metabolism; chronic inflammatory nodules or atypical adenomatous hyperplasia are possible. Please follow up annually with HRCT. c. Multiple solid nodules in both lungs, with normal FDG metabolism; chronic inflammatory nodules are possible. Please follow up with CT to rule out other possibilities. Chronic inflammation and sequelae in both lungs, with an air sac in the lower lobe of the left lung. Mild bronchial dilatation in both lower lobes. Mild pleural thickening bilaterally. Small amount of pericardial effusion. Partial arteriosclerosis (including coronary arteries).

3. Thyroid gland density is uneven; uterus is slightly full in shape, with uneven density and FDG uptake in the uterine body; please correlate with ultrasound examination.

4. Left renal cyst. Hemorrhoidal changes.

5. Localized increased density in the right 5th rib with increased FDG metabolism; please compare with previous images and follow up to rule out metastasis; large bone islands in the right 3rd and 8th ribs; please follow up. Scoliosis with degenerative changes. Mild anterior slippage of the L5 vertebral body. L3 and L4 vertebral endplate inflammation. L3/4 and L4/5 intervertebral disc bulge with pneumatosis and degeneration.

6. Deep lacunar ischemic foci in both cerebral regions, senile encephalopathy. Chronic inflammation of both palatine tonsils. Unclear visualization of both lenses; please correlate with clinical findings.

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.
