Findings

After fasting and intravenous injection of 18F-FDG, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed:Normal brain morphology and structure.
A slightly high-density nodule with indistinct borders was seen on the left side of the sella turcica, with increased FDG uptake (SUVmax = 11.2, long axis approximately 1.5 cm).
Patchy low-density shadows were seen in the deep brain regions bilaterally, with no significant abnormalities in FDG uptake.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal, and there was no midline shift.
Normal morphology and contours of both eyeballs, clear retrobulbar structures, symmetrical optic nerves bilaterally, and no significant abnormalities in FDG uptake.
Thickening of the left maxillary sinus mucosa, with an intact sinus wall.
No thickening of the nasopharyngeal wall was observed.

A localized increase in FDG uptake is observed in the left submandibular gland (SUVmax = 5.1).
The thyroid gland is normal in shape and size, but its density is somewhat uneven; FDG uptake is normal.
A soft tissue nodule measuring approximately 2.7*1.6cm is observed subcutaneously at the root of the left nose, with indistinct borders and increased FDG uptake (SUVmax = 10.0).
No significantly enlarged lymph nodes are observed in the bilateral deep cervical spaces, submandibular region, or submental region.
An irregular soft tissue mass is observed adjacent to the hilum of the left upper lobe of the lung, with indistinct borders, partially extending into the mediastinum, and exhibiting uneven density.
The main bronchus of the left upper lobe is obstructed, with increased FDG uptake (SUVmax = 12.5), an uptake area of approximately 6.1*5.5cm, and a patchy high-density shadow distally.
Multiple solid nodules and plaque-like lesions were observed in both lungs, some with irregular margins.
The largest, approximately 1.0 cm in length, was located in the anterior segment of the right upper lobe.
Some lesions showed increased FDG uptake (SUVmax = 3.1).
A ground-glass nodule approximately 0.6 cm in length was observed in the anterior basal segment of the right lower lobe, with indistinct borders and a maximum CT value of approximately -247 HU.
FDG uptake was normal.
A few linear shadows and small patchy indistinct shadows were observed in both lungs.
Pleural effusion was present on the left side.
Multiple lymph nodes were observed anterior to the trachea and posterior to the vena cava, and below the carina, the largest approximately 1.1 cm in length.
FDG uptake was not significantly increased.
The cardiac silhouette was full, indicating pacemaker implantation.
Calcification was observed in some arterial walls (including the coronary arteries).
No significant thickening or mass was observed in the esophageal wall, and FDG uptake was normal.
An irregular nodule approximately 2.0 x 1.2 cm in size was observed posterior to the right nipple, with clear borders and increased FDG uptake (SUVmax = 7.1).
Nodular FDG uptake was observed in the right pectoralis major muscle, SUVmax = 8.3.
The liver showed no obvious abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Multiple cystic lesions were observed in the liver parenchyma, the largest being approximately 3.0 cm in length in the left lateral lobe, with absent FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, with a rough wall and punctate and patchy high-density shadows within, but no abnormal FDG uptake.
The pancreas showed no abnormalities in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen showed no abnormalities in shape or size, density, or FDG uptake.
Both kidneys are irregularly shaped, with cystic lesions in both kidneys.
The largest lesion, approximately 2.0 cm in length, is located in the left kidney, with absent FDG uptake.
No widening of the renal pelvis, calyces, or ureters is observed, and no positive stones are found within them.
A soft tissue nodule measuring approximately 2.9*1.8 cm is seen in the left adrenal gland, with increased FDG uptake (SUVmax = 7.1).
The right adrenal gland is thickened with calcification, also with increased FDG uptake (SUVmax = 2.5).
Solid nodules are seen in the left perirenal fascia and left paracolic gutter, the larger one (approximately 1.1 cm in length) with increased FDG uptake (SUVmax = 2.9).
A lymph node approximately 0.5 cm in length is seen in the right prediaphragmatic group, with increased FDG uptake (SUVmax = 2.5).
No significant fluid accumulation is observed in the abdominal or pelvic cavities.
Gastric distension is poor, but FDG uptake is not significantly abnormal.
Bowel preparation was poor; no obvious masses were observed in the intestinal wall; FDG uptake was physiological.
The prostate was enlarged, partially protruding into the bladder cavity; the parenchyma density was uneven with calcification; nodular FDG uptake was observed in the left peripheral zone (SUVmax = 5.6).
Bladder filling was poor; no obvious positive stones were observed.
Bone destruction was observed in the right 1st and 4th ribs and T7 vertebral body appendages; FDG uptake was increased (SUVmax = 12.0).
A small nodule with a long diameter of approximately 0.8 cm was observed subcutaneously on the upper medial aspect of the right thigh; FDG uptake was increased (SUVmax = 4.5).
The spinal alignment was normal; some vertebral body margins showed osteophyte formation; L4/5 disc herniation and L5/S1 disc bulging were present.
Nuchal ligament calcification was also observed.

Impression

1. a. A soft tissue mass near the hilum of the left upper lobe with increased FDG metabolism, strongly suggestive of lung cancer; please correlate with clinical findings and pathology. Left pleural effusion. b. Possible reactive hyperplasia of mediastinal lymph nodes; metastasis to the right anterior diaphragmatic lymph nodes needs to be ruled out; follow-up is recommended. c. Multiple solid nodular plaque lesions in both lungs, some with increased FDG metabolism, suggesting possible metastases; some chronic inflammatory lesions cannot be ruled out; regular follow-up with CT scans is recommended. d. Bone metastases in the right 1st and 4th ribs and T7 vertebral appendages. Left adrenal metastasis; right adrenal metastasis needs to be ruled out. e. Multiple metastases are highly likely in the subcutaneous tissue of the left nasal root, right pectoralis major muscle, subcutaneous tissue of the upper medial aspect of the right thigh, behind the right nipple, left perirenal fascia, and left paracolic gutter; please correlate with clinical findings and follow-up.

2. Benign prostatic hyperplasia with calcification, nodular FDG hypermetabolic lesions in the left peripheral zone, prostate cancer to be ruled out; further examination with PSA and enhanced MRI is recommended.

3. Ground-glass nodule in the anterior basal segment of the right lower lobe, FDG metabolism normal, suggestive of chronic inflammatory nodule or atypical adenomatous hyperplasia; please combine with annual follow-up via HRCT. Chronic inflammation and sequelae in both lungs.

4. Full cardiac silhouette, post-pacemaker implantation. Partial arteriosclerosis (including coronary arteries).

5. Liver cysts. Gallstones, chronic cholecystitis. Bilateral renal cysts.

6. Spinal degenerative changes. L4/5 disc herniation, L5/S1 disc bulge.

7. A slightly high-density nodule on the left side of the sellar region with increased FDG metabolism, suggesting a possible space-occupying lesion. Enhanced MRI of the sellar region is recommended.

8. Bilateral deep cerebral ischemic lesions, age-related brain. Chronic inflammation of the left maxillary sinus. Possible physiological or inflammatory changes in the left submandibular gland; 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.
