Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed:Normal brain morphology and structure, with punctate low-density lesions in the deep bilateral cerebral regions; no significant abnormalities in FDG metabolism.
Enlargement of the ventricles, sulci, fissures, and cisterns; symmetrical bilateral ventricles; no midline shift.
Normal bilateral eyeball morphology and contour; clear retrobulbar structures; symmetrical bilateral optic nerves; no abnormal FDG metabolism.
Slight thickening of the mucosa in the right ethmoid sinus and bilateral maxillary sinuses; intact sinus walls; absent FDG metabolism.
No thickening of the nasopharyngeal wall; no stenosis of the bilateral pharyngeal recesses and Eustachian tube openings; normal structures of the infratemporal fossa and pterygopalatine fossa; clear bilateral parapharyngeal spaces; no abnormal FDG metabolism.
Physiological FDG metabolism in the oropharynx and laryngopharynx.
No abnormal contrast enhancement of the bilateral parotid and submandibular glands.
Rightward deviation of the nasal septum.
The thyroid gland is normal in shape and size, with slightly heterogeneous density; FDG metabolism is normal.
Small lymph nodes are visible in the bilateral deep cervical spaces, the largest with a short diameter of approximately 0.6 cm; FDG metabolism is normal.
An irregular soft tissue density mass is seen at the anterior basal segment of the right lower lobe bronchus, with relatively clear borders, measuring approximately 5.9*6.3*5.6 cm in cross-section; FDG metabolism is increased, SUVmax=13.0; the mass locally compresses and pulls on the adjacent oblique fissure pleura.
Multiple solid nodules are present in both lungs, some lobulated, with clear borders; the largest measures approximately 1.5*1.1 cm in cross-section; some have increased FDG metabolism, SUVmax=9.2.
Scattered mixed ground-glass opacities are present in both lungs, more pronounced in the right lung, with indistinct borders; FDG metabolism is slightly increased, SUVmax=2.4.
A few linear lesions and calcifications are also seen in both lungs; FDG metabolism is normal.
A strip-shaped air-filled band was seen in the right pleural cavity, with a small amount of pleural effusion.
Bilateral hilar, mediastinal (pretracheal, posterior to the vena cava, aortic window, parapulmonary arch, and subcarinal) and bilateral clavicular fossa lymph nodes were visualized, the largest measuring approximately 2.8*1.6cm, with increased FDG metabolism and an SUVmax of 5.2.
The cardiac silhouette was normal.
Some arterial walls showed calcification.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
A slightly low-density lesion with indistinct borders, measuring approximately 1.5*1.1cm, was seen near the liver capsule at the junction of the left and right lobes on plain CT scan, with slightly reduced FDG metabolism compared to background levels.
A low-density nodule with smooth edges, approximately 2.8cm in length, was seen within the parenchyma of the left lateral lobe of the liver, with absent FDG metabolism.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was absent post-operatively.
The pancreas is normal in shape, with no obvious abnormal density shadows seen in the parenchyma.
The main pancreatic duct is not widened, and FDG metabolism is normal.
The spleen is normal in shape, size, density, and FDG metabolism.
Both kidneys are normal in shape and size, with a high-density shadow seen in the parenchyma of the left kidney; FDG metabolism is normal.
The renal pelvis, calyces, and ureters are not widened, and FDG metabolism is normal.
The adrenal junctions are thickened, more pronounced on the left, and FDG metabolism is normal.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or swollen; FDG metabolism is not increased.
The stomach is generally full, with no significant thickening of the stomach wall; FDG metabolism is normal.
The intestines are poorly full, with no significant thickening or swollen intestinal wall; FDG metabolism is physiological.
The prostate is slightly enlarged, with a transverse diameter of approximately 4.5 cm.
High-density shadows are seen within the parenchyma.
FDG metabolism is uneven, with an SUVmax of 4.5.
The bladder is poorly filled, but no obvious positive stones are seen.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region.
No significant fluid accumulation is seen in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral body margin osteophytes.
L4/5 and L5/S1 intervertebral disc bulges, with normal FDG metabolism.
Multiple bone density changes are observed in the right 2nd rib, localized sternum, right 8th rib, left 3rd rib, left acetabulum, and right proximal femur, with increased FDG metabolism (SUVmax = 5.4).
A cystic low-density lesion with regular sclerotic borders is seen in the right iliac bone, measuring approximately 1.3 x 0.8 cm, with normal FDG metabolism.

Impression

1. a. A mass in the anterior basal segment of the right lower lobe, with increased FDG metabolism, consistent with lung cancer involving the adjacent oblique fissure pleura. Right-sided pneumothorax. Small amount of right-sided pleural effusion. b. Multiple solid metastases in both lungs. Metastasis to the hilar, mediastinal, and bilateral clavicular fossa lymph nodes. c. Scattered minor inflammatory changes in both lungs, more pronounced in the right lung; minor post-inflammatory remnants (including calcification) in both lungs. Partial arteriosclerosis. d. Multiple bone density changes in the right 2nd rib, localized sternum, right 8th rib, left 3rd rib, left acetabulum, and right proximal femur, with increased FDG metabolism; partial bone metastasis cannot be ruled out. Close follow-up based on clinical findings is recommended. e. Age-related brain changes, deep lacunar infarcts in the brain; contrast-enhanced MRI is recommended.

2. Bilateral adrenal hyperplasia is highly probable; close follow-up with CT is recommended.

3. Hemangioma at the junction of the left and right lobes of the liver is highly probable; enhanced MRI is recommended. Left lateral lobe hepatic cyst. Post-cholecystectomy absence. Left renal parenchymal calcification.

4. Uneven FDG metabolism in the prostate; follow-up with MRI and PSA is recommended to rule out tumors. Mild prostatic hyperplasia with calcification.

5. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge. Benign bone disease of the right iliac bone; specialist follow-up is recommended.

6. Minor inflammation of the right ethmoid sinus and bilateral maxillary sinuses. Right deviation of the nasal septum. Reactive hyperplasia of bilateral deep cervical lymph nodes. Uneven thyroid density; follow-up with ultrasound is recommended.

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.
