A low-density nodule with a long diameter of approximately 1.1 cm was observed in the left lobe of the thyroid gland.
The borders were relatively clear, and FDG uptake was normal.
Small lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
FDG uptake was normal.
An irregular soft tissue density lesion measuring approximately 4.8*4.9*4.1 cm was observed in the left lower lobe of the lung.
The lesion had clear borders, relatively uniform density, lobulated edges, and spiculated margins.
The boundary with the adjacent pleura was unclear, and a local bronchus was truncated.
FDG uptake was increased, with SUVmax = 25.3.
Multiple solid nodules were observed in both lungs.
The largest nodule, located in the posterior basal segment of the right lower lobe, had a long diameter of approximately 0.7 cm and clear borders.
FDG uptake was normal.
Interlobular septa were thickened in both lungs, with scattered linear shadows and small patchy indistinct shadows.
A linear shadow was observed in the left lower lobe.
Scattered air-containing cavities were observed in both lungs.
FDG uptake was normal.
There was no pleural effusion or pneumothorax on either side.
Enlarged lymph nodes were seen in the left hilum, the largest approximately 1.0 cm in short diameter, with increased FDG uptake (SUVmax = 6.6).
Several small lymph nodes were also seen in the mediastinum and both axillae, the largest approximately 0.5 cm in short diameter, some with increased FDG uptake (SUVmax = 3.4).
The cardiac silhouette was normal, and myocardial FDG uptake was normal.
Calcification was observed in some arterial walls (including the coronary arteries).
No significant thickening or mass was seen in the esophageal wall, and FDG uptake was not increased.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
Several cystic lesions were seen in the liver parenchyma, the largest approximately 0.5 cm in long diameter, with no abnormal FDG uptake.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder's shape and size are normal; the gallbladder wall is not thickened; no positive stones or obvious masses are seen within; FDG uptake is normal.
The pancreas's shape is normal; no obvious abnormal density shadows are seen in the parenchyma; the main pancreatic duct is not widened; FDG uptake is normal.
The spleen's shape and size are normal; density and FDG uptake are normal.
Accessory splenic nodules are seen around the spleen.
Both kidneys' shape and size are normal; no obvious abnormal density shadows are seen in the renal parenchyma; FDG uptake is normal.
The renal pelvis, calyces, and ureters are not widened; no positive stones are seen within.
The adrenal glands' shape and density are normal; FDG uptake is normal.
The stomach is poorly filled; FDG uptake is increased in some parts of the stomach wall; SUVmax = 2.6.
Bowel preparation was poor; no obvious masses were observed in the intestinal wall, but FDG uptake was increased in some intestinal segments (SUVmax = 8.0).
The prostate gland showed no abnormalities in morphology or size, with a transverse diameter of approximately 4.6 cm.
FDG uptake in the parenchyma was uneven (SUVmax = 3.7).
Bladder distension was poor, but no obvious positive stones were observed.
Small lymph nodes were observed in the retroperitoneal para-aortic region, mesenteric space, and bilateral inguinal regions; FDG uptake was normal.
No significant fluid accumulation was observed in the abdomen or pelvis.
The L5 vertebral body showed sacralization.
The L3 and L4 vertebral bodies were slightly displaced.
Compression changes were observed in the L3 vertebral body.
A round, low-density lesion was observed in the T8 vertebral body, containing coarse trabeculae in a palisade-like pattern; FDG uptake was normal.
Osteophyte formation was observed at the marginal of some vertebral bodies.
L3/4 and L4/5 intervertebral disc bulges were observed, the latter accompanied by pneumothorax.
FDG uptake in all bones was normal.
Increased FDG uptake in the right sternoclavicular joint, SUVmax=3.4.

Impression

1. a. A mass in the lower lobe of the left lung with increased FDG metabolism, suggestive of lung cancer. Please confirm the diagnosis with pathology. b. Left hilar lymph node metastasis, likely with reactive hyperplasia of mediastinal and bilateral axillary lymph nodes. c. Bilateral solid nodules with normal FDG metabolism, suggestive of chronic inflammatory nodules. Please follow up with CT scan. Bilateral interstitial lung changes with chronic inflammation and sequelae. Emphysema. Partial arteriosclerosis (including coronary arteries).

2. Liver cyst. Uneven FDG metabolism in the prostate parenchyma, likely physiological or chronic inflammatory. Please follow up with PSA.

3. Increased FDG metabolism in parts of the stomach wall and intestines, suggestive of physiological uptake or chronic inflammation. Please follow up with endoscopy.

4. Reactive hyperplasia of retroperitoneal para-aortic, mesenteric, and bilateral inguinal lymph nodes.

5. Spinal degenerative changes. L3 and L4 vertebral instability. L3 vertebral compression changes. T8 vertebral hemangioma. L3/4 and L4/5 intervertebral disc bulging, the latter with pneumoconiosis and degeneration. Right sternoclavicular arthritis.

6. Bilateral deep lacunar infarcts, age-related brain; MRI recommended.

7. Low-density nodule in the left lobe of the thyroid gland; FDG metabolism normal; nodular goiter suspected; ultrasound follow-up recommended. Reactive hyperplasia of cervical 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.
