The thyroid gland was normal in shape and size, with homogeneous density; FDG uptake was not abnormal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region; FDG uptake was not abnormal.
An irregular soft tissue mass was observed on the diaphragmatic surface of the right lung, primarily located in the basal segment of the lower lobe, with some protruding into the right middle lobe.
The mass had indistinct borders, uneven density, lobulated edges, and spiculation.
A local bronchial transection was observed, along with thickened adjacent pleura.
FDG uptake was increased (SUVmax = 18.9), and the mass measured approximately 5.2 x 4.4 cm.
Multiple soft tissue nodules were observed in the upper lobe of the left lung, the largest measuring approximately 2.6 x 2.3 cm near the hilum, with increased FDG uptake (SUVmax = 25.5) and an irregular shape.
Scattered punctate, linear, and patchy opacities were observed in both lungs, with calcifications in the upper and lower lobes.
Multiple lymph nodes were seen in the left hilum, superior mediastinal intervascular space, pretracheal vena cava, para-aortic arch, subcarinal region, hepatogastric space, and retroperitoneum of the upper abdomen.
The largest, located pretracheal vena cava, had a short diameter of approximately 2.4 cm, with increased FDG uptake (SUVmax = 23.5).
Nodular thickening of the pleura was observed bilaterally, with increased FDG uptake (SUVmax = 7.8), and bilateral pleural effusions.
A small amount of pericardial effusion was present.
The cardiac silhouette appeared normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, no significant thickening or mass in the esophagus, and no increased FDG uptake.
Multiple low-density nodules and masses were observed in the liver parenchyma, some of which were fused together with indistinct borders.
The largest nodule, measuring approximately 4.5*4.7cm, was located in the right lobe of the liver.
FDG uptake was increased, with SUVmax = 22.3.
No significant widening of the main portal vein was observed, and no dilation of intrahepatic or extrahepatic bile ducts was seen.
The gallbladder showed no abnormalities in shape or size, and the gallbladder wall was not thickened.
No positive stones or obvious masses were observed within the gallbladder, and FDG uptake was normal.
The pancreas showed no abnormalities in shape, and no significant abnormal density shadows were observed in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape or size, density, or FDG uptake.
Both kidneys showed no abnormalities in shape or size, and no significant abnormal density shadows were observed in the renal parenchyma.
FDG uptake was normal.
No widening of the renal pelvis, calyces, or ureters was observed bilaterally, and no positive stones were seen within them.
A slightly low-density nodule measuring approximately 2.3*1.4cm was seen in the right adrenal gland, with a CT value of approximately 1 HU; FDG uptake was normal.
The left adrenal gland showed no abnormalities in morphology or density, and FDG uptake was normal.
Gastric distension was poor, but FDG uptake was not significantly abnormal.
Bowel preparation was poor; no obvious mass was seen in the intestinal wall, and FDG uptake was physiological.
The prostate showed no abnormalities in morphology or size, with a transverse diameter of approximately 4.4cm.
Calcifications were observed in the parenchyma, and a nodular FDG uptake with increased FDG uptake (SUVmax=3.0, long axis approximately 1.0cm) was seen at the right anterior margin of the central part.
Bladder distension was poor, and no obvious positive stones were seen within it.
No significant fluid accumulation was observed in the abdomen or pelvis.
The left inguinal canal was widened, containing a roundish low-density shadow.
The L2 and L3 vertebral bodies were slanted backward.
The T12 and L1 vertebral bodies are slightly flattened, with some vertebral body margins showing osteophyte formation.
FDG uptake in the T12 vertebral body is increased, with SUVmax = 6.9.
There is a bulging L2-S1 intervertebral disc.
FDG uptake around both shoulder joints is increased, with SUVmax = 3.9.

Impression

1. a. A soft tissue mass on the diaphragmatic surface of the right lung with increased FDG metabolism, highly suggestive of lung cancer; please confirm with pathology. Bilateral pleural metastases, small amounts of pleural effusion bilaterally. b. Multiple soft tissue nodules in the upper lobe of the left lung with increased FDG metabolism, highly suggestive of malignancy; both metastatic and primary lesions are possible. Please confirm with clinical findings; biopsy may be necessary. c. Metastasis to the left hilar, mediastinal, hepatogastric space, and retroperitoneal lymph nodes in the upper abdomen. d. Multiple liver metastases; please confirm with contrast-enhanced MRI. T12 vertebral bone metastasis to be ruled out.

2. Chronic inflammation and sequelae in both lungs. Partial arteriosclerosis (including coronary arteries). Small amount of pericardial effusion.

3. Highly suggestive of right adrenal adenoma; please follow up. Highly suggestive of left inguinal hernia.

4. Prostatic calcifications, with a nodular FDG hypermetabolic lesion at the right anterior margin in the central part, suggestive of inflammatory changes. Please confirm with PSA and enhanced MRI to rule out space-occupying lesions.

5. Spinal degeneration. L2-3 vertebral instability. T12-L1 vertebral wedging. L2-S1 intervertebral disc bulge. Bilateral frozen shoulder.

6. Bilateral deep cerebral ischemic lesions, age-related brain; please confirm with MRI.

7. Solid nodule in the deep lobe of the right parotid gland with increased FDG metabolism, suggestive of adenolymphoma or mixed tumor; please follow up to rule out other possibilities.

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.
