Some showed slightly increased FDG metabolism, with an SUVmax of 2.3.
The cardiac silhouette appeared normal.
Calcification of some arterial walls (including the coronary arteries) was observed.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth borders, no widening of the hepatic fissure, and no significant abnormal density shadows in the liver parenchyma on plain CT scan.
FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.

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 showed no abnormalities in shape, size, density, or FDG uptake.
A roughly round protrusion was observed in the parenchyma at the inner margin of the right kidney, with a CT value of approximately 24 HU, a cross-sectional size of approximately 1.7*1.8 cm, smooth margins, and increased FDG metabolism (SUVmax = 3.8).
A low-density nodule with smooth margins and a long diameter of approximately 0.9 cm was observed in the parenchyma of the left kidney, with absent FDG uptake.
No widening of the renal pelvis, calyces, or ureters was observed bilaterally, and no obvious abnormalities in FDG uptake were observed.
The renal bridging septa were thickened bilaterally.
No obvious abnormalities were observed in the bilateral adrenal glands upon contrast imaging.
Stomach fullness is normal, with slight thickening of the antral wall and slightly increased FDG uptake (SUVmax = 2.7).
Intestinal fullness is poor, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
Prostate morphology is normal, transverse diameter is approximately 4.5 cm, calcifications are seen in the parenchyma, and FDG uptake is normal.
Bladder fullness is poor, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneum.
No obvious fluid accumulation is seen in the abdomen or pelvis.
Spinal alignment is normal, with localized calcification of the nuchal ligament and osteophyte formation at the margins of some vertebral bodies.
Dense bone shadow is seen at the upper margin of the L2 vertebral body.
L3/4 and L4/5 intervertebral disc bulges, with no abnormal FDG uptake.
L2/3 and L5/S1 intervertebral disc herniation is present, with no significant abnormalities in FDG metabolism.
L5/S1 intervertebral disc pneumoconiosis.
L5 lumbarization.
Localized tortuosity and osteophyte formation in the left 11th posterior rib.
No obvious abnormalities were found in FDG metabolism.

Impression

1. a. Left hilar mass with abnormally elevated FDG metabolism, suggestive of central lung cancer with left lower lobe atelectasis and local involvement of the left upper lobe bronchus. Reactive hyperplasia of bilateral hilar and mediastinal lymph nodes, follow-up recommended. b. Mixed ground-glass opacity nodule in the left upper lobe, no significant abnormalities in FDG metabolism, suggestive of chronic inflammatory nodule or atypical adenomatous hyperplasia, annual HRCT recommended. c. Chronic inflammatory nodule (solid) in the anterior segment of the right upper lobe. Interstitial inflammation in the right lower lobe. Bulla in the left upper lobe. Scattered chronic inflammation and remnants in both lungs. Small amount of pleural effusion on the left side. Partial arteriosclerosis (including coronary arteries). d. Age-related brain changes, deep lacunar infarcts in the brain, MRI recommended.

2. a. A localized, roundish soft tissue density nodule on the inner edge of the right kidney parenchyma, with increased FDG metabolism, suggesting a possible cyst, but renal cell carcinoma cannot be ruled out. Please combine with contrast-enhanced CT or MRI. b. Left renal cyst. Thickening of the bilateral renal septa. Benign prostatic hyperplasia with calcification.

3. Nodular goiter, possibly a left lobe thyroid adenoma with calcification. Ultrasound and thyroid function follow-up are recommended.

4. Increased FDG metabolism in part of the gastric wall, suggesting physiological uptake or chronic inflammatory changes.

5. Degenerative changes in the spine. L2 vertebral islet. L3/4 and L4/5 intervertebral disc bulge. L2/3 and L5/S1 intervertebral disc herniation. L5/S1 intervertebral disc pneumoconiosis and degeneration. L5 lumbarization. Possible old fracture of the left 11th posterior rib.

6. Mild inflammation of the left sphenoid sinus, submucosal cyst of the right maxillary sinus. Reactive hyperplasia of bilateral submandibular lymph nodes.

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.
