Solid nodules are seen in the anterior segment of the left upper lobe and the lateral basal segment of the right lower lobe, with clear borders.
The former is larger, approximately 2.4*1.4cm, with unclear boundaries from the adjacent pleura; increased FDG metabolism, SUVmax=18.2.
Several small solid nodules, approximately 0.2?.4 cm in long diameter, were observed in both lungs; FDG uptake was normal.
A few small patchy, hazy shadows were seen in the lower lobe of the left lung, and an air-filled cystic cavity was observed in the subpleural region of the upper lobe of the left lung.
There was no pleural effusion or pneumothorax bilaterally.
Several lymph nodes were seen in the mediastinum, the largest approximately 0.6 cm in short diameter; FDG uptake was normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The cardiac chamber density was lower than that of the myocardium.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was normal.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma; FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder appears normal in shape and size, with no thickening of the gallbladder wall.
Small patchy high-density shadows are seen within the gallbladder, and FDG uptake is normal.
A slightly low-density nodule with indistinct borders, approximately 1.0*0.6cm in size, is seen in the body and tail of the pancreas.
FDG metabolism is increased, SUVmax=4.9.
The spleen appears normal in shape, size, density, and FDG uptake.
Both kidneys appear normal in shape and size.
A nodular FDG uptake is seen in the parenchyma of the lower pole of the left kidney, SUVmax=4.5, with an uptake area of approximately 1.0*0.7cm.
No abnormal density shadows are seen on the same CT scan.
No widening of the renal pelvis, calyces, or ureters is seen bilaterally, and FDG uptake is normal.
No significant abnormalities are seen in the bilateral adrenal glands.
The stomach is poorly distended, with no significant thickening of the stomach wall and no significant abnormalities in FDG uptake.
Intestinal distension was poor, with no obvious thickening or masses in the intestinal wall; FDG uptake was physiological.
The prostate was normal in size and shape, with calcifications observed, but no abnormal FDG metabolism was seen.
The bladder wall showed no abnormal thickening, and no obvious positive stones were observed.
Multiple enlarged lymph nodes were observed in the retroperitoneum and bilaterally adjacent to the common iliac arteries, the largest with a short diameter of approximately 1.2 cm; FDG metabolism was increased, with SUVmax = 12.1.
No obvious fluid accumulation was observed in the abdomen or pelvis.
Bone destruction was observed in the parietal bone, right mandible, left clavicle, left scapula, right humeral head, multiple ribs bilaterally, multiple vertebrae and their appendages in the spine, bilateral iliac bones, sacrum, left acetabulum, and upper left femur; FDG metabolism was increased, with SUVmax = 13.4.
Nodular FDG uptake was observed in the left gluteus maximus, with SUVmax = 2.3.
Decreased FDG metabolism in some cervical and upper thoracic vertebrae (post-radiotherapy changes).
Osteophyte formation at the vertebral margins in some areas.
L4/5 and L5/S1 intervertebral disc bulges.

Impression

1. a. Soft tissue mass in the upper and middle lobes of the right lung with increased FDG metabolism; solid nodules in the anterior segment of the left upper lobe and the lateral basal segment of the right lower lobe with increased FDG metabolism; slightly low-density nodules in the body and tail of the pancreas with increased FDG metabolism; enlarged lymph nodes in the retroperitoneum and bilateral common iliac arteries with increased FDG metabolism; multiple bone destruction throughout the body with increased FDG metabolism; nodular FDG hypermetabolic foci in the left gluteus maximus muscle. Considering all of the above, this is likely a malignant tumor, possibly lymphoma with multi-systemic infiltration, and lung cancer with multiple metastases should be ruled out. Please confirm the diagnosis with pathological examination. b. Small solid nodules in the remaining two lungs, with normal FDG metabolism, suggestive of chronic inflammatory nodules. Please follow up with CT scans to rule out other possibilities. Slight inflammation in the left lower lobe, and paraseptal emphysema in the left upper lobe. Possible reactive hyperplasia of mediastinal lymph nodes. Calcification of some arterial walls (including coronary arteries). Anemia.

2. Nodular FDG hypermetabolic lesion in the lower pole of the left kidney. No abnormal density shadows were seen on the same CT scan. Physiological change is considered possible. Occult space-occupying lesion needs to be ruled out. Enhanced MRI is recommended for follow-up.

3. After comprehensive treatment for left tongue cancer: No obvious signs of tumor recurrence were seen in the surgical area. No enlarged lymph nodes were seen in both sides of the neck. Please follow up with clinical and enhanced MRI findings. Increased FDG metabolism in the left lateral pterygoid muscle is considered likely to be a physiological change.

4. Localized high-density lesion in the left parietal lobe. No abnormal FDG metabolism was seen. Benign lesion is considered possible. Enhanced MRI is recommended to rule out other possibilities. A few ischemic lesions in the deep brain, age-related brain changes.

5. Gallstones. Prostatic calcification.

6. Partial vertebral osteophyte formation. L4/5 and L5/S1 intervertebral disc bulge.

7. Chronic inflammation of the right maxillary sinus. Inflammatory changes in the right maxillary gingival region are likely significant; please consult a specialist.

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.
