Scattered multiple cystic lucent shadows and a few linear shadows were observed in both lungs.
A few patchy ground-glass opacities were seen in the lower lobe of the left lung.
FDG uptake was normal.
Slight pleural thickening was observed in some areas, but no significant pleural effusion was seen bilaterally.
Enlarged right hilar lymph nodes were observed with increased FDG uptake (SUVmax = 7.9).
Flat lymph nodes were visible in the subcarinal, pretracheal, posterior vena cava, and aortopulmonary window, the largest with a short diameter of approximately 0.7 cm and increased FDG uptake (SUVmax = 6.7).
The heart was slightly enlarged.
Calcification was observed in the walls of the aorta and its branches (including the coronary arteries).
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissures.
No significant abnormal density shadows were observed in the liver parenchyma, and FDG uptake was normal.
No dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall.
Small patchy high-density lesions are seen within the gallbladder fossa, and FDG uptake in the gallbladder fossa is normal.
The peripancreatic spaces are clear, with no obvious abnormal density shadows in the parenchyma.
The pancreatic duct is not widened, and FDG uptake is normal.
The spleen is basically normal in shape and size, with no abnormalities in density or FDG uptake.
The bilateral adrenal glands are normal in shape, size, and density, with no abnormalities in local FDG uptake.
The kidneys are normal in shape and size, with a few patchy and linear shadows around the kidneys.
An oval low-density lesion with a long diameter of approximately 1.5 cm is seen in the parenchyma of the left kidney, with absent FDG uptake.
No obvious abnormal density shadows are seen in the parenchyma of the right kidney, and FDG uptake is normal.
No widening of the renal pelvis, calyces, or ureters is seen bilaterally, and no positive stones are seen locally.
The prostate is enlarged with punctate calcifications.
FDG uptake is uneven, SUVmax=3.9.
The bladder is poorly filled, with no positive stones observed in the lumen.
The esophagus is not dilated, and the wall is not significantly thickened or swollen.
FDG uptake in the lower esophagus is increased, SUVmax=4.6.
The stomach is adequately filled, with increased FDG uptake in the cardia and fundus, SUVmax=5.2.
The gastric angle and antrum show thickening of the gastric wall with localized depression at the posterior margin, and increased FDG uptake, SUVmax=6.4.
The intestines are not sufficiently filled, with no localized masses.
FDG uptake is increased in some intestinal segments, SUVmax=5.5.
A pneumatic cavity is seen in the descending duodenum, with normal FDG uptake.
Several enlarged lymph nodes are seen on the lesser curvature of the stomach, the largest measuring approximately 1.70.9cm, with normal FDG uptake.
No enlarged lymph nodes were observed in the retroperitoneal para-aortic region, and FDG uptake was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
Increased FDG uptake was observed in some muscles of the right abdomen, with an SUVmax of 3.4.
The spinal alignment was normal, with some vertebral body margin osteophytes, a fence-like appearance in the L1 vertebral body, and L4/5 intervertebral disc bulging; FDG uptake was normal.
Increased FDG uptake was observed around both shoulder joints and the right acromioclavicular joint, with an SUVmax of 7.8.
A low-density fat lesion measuring approximately 1.7 0.8 cm was observed within the left trapezius muscle; FDG uptake was normal.

Impression

1. a. A mass in the posterior segment of the right upper lobe with significantly increased FDG metabolism in the solid portion, suggestive of lung cancer with minor obstructive pneumonia. Please confirm with pathology. b. Possible right hilar lymph node metastasis, highly likely reactive mediastinal lymph node hyperplasia. Please follow up with CT. c. Chronic inflammatory solid micronodules in both lungs, a few inflammatory ground-glass opacities in the left lower lobe. Bilateral emphysema with bullae, bilateral pulmonary fibrosis.

2. a. Thickening of the gastric angle and antrum with ulceration and increased FDG metabolism suggest possible gastritis, but gastric cancer cannot be ruled out. Further gastroscopy is recommended. b. Physiological or inflammatory uptake in the lower esophagus, cardia, fundus, and part of the intestine. Duodenal diverticulum. c. Enlarged lymph nodes on the lesser curvature of the stomach, with no increase in FDG metabolism, suggesting possible reactive lymph node hyperplasia. Please follow up with CT to rule out other possibilities.

3. Benign prostatic hyperplasia with calcification, uneven FDG metabolism; please follow up with MRI. Gallstones. Thickened perirenal septum bilaterally, left renal cyst.

4. Slightly enlarged heart. Partial arteriosclerosis (including coronary arteries).

5. Degenerative changes in the spine, L1 vertebral hemangioma, L4/5 intervertebral disc bulge. Bilateral shoulder joint and right acromioclavicular joint periarthritis. Left trapezius muscle lipoma. Physiological uptake of some muscles in the right abdomen.

6. No obvious abnormalities seen on cranial scintigraphy. Minor chronic inflammation of the right maxillary sinus.

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.
