The bilateral eyeballs had normal morphology and contours, clear retrobulbar structures, symmetrical optic nerves, and no significant abnormalities in FDG uptake.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.

The bilateral infratemporal fossa and pterygopalatine fossa structures were normal, and the bilateral parapharyngeal spaces were clear, with no abnormalities in FDG uptake.
The bilateral palatine tonsils were full, and FDG uptake was physiological.
The laryngopharynx morphology and structure were normal.
No abnormal contrast was observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uneven density, and increased FDG uptake (SUVmax = 2.7).
Small lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake was normal.
A pneumocystic cavity was observed in the anterior basal segment of the right lower lobe, with a soft tissue mass at the periphery, approximately 2.2*2.1 cm in cross-section, with clear borders, lobulated edges, and spiculation.
The adjacent pleura was retracted, and a local bronchus was truncated; FDG uptake was increased (SUVmax = 6.2).
Patchy and strip-shaped high-density shadows were observed in the upper lobes of both lungs, with long and short linear bands at the edges and small vacuoles within; FDG uptake was increased (SUVmax = 4.5).
Multiple solid nodules, approximately 0.3-0.4 cm in length, with clear borders, were observed in the upper lobes of both lungs and the lower lobe of the right lung.
Scattered linear and patchy hazy shadows were also seen in both lungs.
Air-filled cavities and bullae were observed in both lungs.
FDG uptake was normal.
Mild pleural thickening was observed bilaterally, but there was no pleural effusion or pneumothorax.
Multiple lymph nodes were observed bilaterally in the hilum, pretracheal space, aortopulmonary window, and paraesophageal region of the posterior mediastinum.
The largest lymph node had a short diameter of approximately 0.6 cm and increased FDG uptake (SUVmax = 3.5).
The cardiac silhouette was normal, and myocardial FDG uptake was normal.
No significant thickening or mass was observed in the esophageal wall, and FDG uptake was normal.
Right breast development was observed.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
The liver parenchyma showed decreased density, with a CT value of approximately 36 HU, and FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall, no positive stones or obvious masses, and no abnormal FDG uptake.
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 was normal in shape and size, density, and FDG uptake.
Both kidneys were normal in shape and size; several cystic lesions were observed in the left kidney, the largest being approximately 1.1 cm in long diameter, and FDG uptake was normal.
The renal pelvis, calyces, and ureters were not widened, and no positive stones were observed.
The adrenal glands were normal in shape and density, and FDG uptake was normal.
The stomach was poorly distended, with increased FDG uptake in some parts of the gastric wall; SUVmax = 4.4.
Bowel preparation was poor; no obvious masses were observed in the intestinal wall; FDG uptake was physiological.
The prostate gland was enlarged with calcifications in the parenchyma; FDG uptake was unevenly increased (SUVmax = 5.8).
FDG uptake was increased bilaterally in the seminal vesicles (SUVmax = 7.9).
Increased FDG uptake was observed bilaterally in the scrotum (SUVmax = 11.5).
Bladder distension was poor; no obvious positive stones were observed.
Several lymph nodes were visible bilaterally in the pelvic walls, the largest with a short diameter of approximately 0.5 cm; some showed increased FDG uptake (SUVmax = 2.6).
No obvious fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment was normal; the S1 vertebra was lumbarized.
Osteophytes were present at the margins of some vertebral bodies; a nodular low-density shadow with slightly sclerotic margins was seen in the L4 vertebral body; FDG uptake was normal.
L4/5 and L5/S1 intervertebral disc bulges were observed.
Increased FDG uptake was observed in the bone marrow cavity, with SUVmax=5.3.

Impression

1. a. Right lower lobe anterior basal segment containing air-filled cavities and soft tissue nodules, with increased FDG metabolism, suggestive of lung cancer. Please confirm the diagnosis with pathological examination. Reactive hyperplasia of hilar and mediastinal lymph nodes bilaterally. b. Patchy and strip-shaped high-density shadows in the upper lobes of both lungs, with increased FDG metabolism, suggestive of infectious lesions. Please compare with previous data and follow up to rule out other possibilities. c. Chronic inflammatory micronodules (solid) in the upper lobes of both lungs and the right lower lobe. Chronic inflammation and sequelae in both lungs, emphysema, bullae. Mild pleural thickening bilaterally.

2. a. Benign prostatic hyperplasia with calcification, with unevenly increased FDG metabolism in the parenchyma; increased FDG metabolism in both seminal vesicles; high FDG metabolism foci in both scrotums. Considering the above, inflammatory changes are possible. Please rule out space-occupying lesions with PSA and enhanced MRI. b. Reactive hyperplasia of bilateral pelvic wall lymph nodes.

3. Fatty liver, no abnormalities in FDG metabolism in liver parenchyma. Left renal cyst.

4. Increased FDG metabolism in part of the gastric wall, considered physiological uptake or chronic inflammation; please follow up with endoscopy.

5. Spinal degenerative changes. Benign bone disease of L4 vertebral body. L4/5 and L5/S1 intervertebral disc bulge. Increased FDG metabolism is observed in multiple medullary cavities, suggesting a high probability of bone marrow proliferative changes.

6. No obvious abnormalities seen on cranial scintigraphy. Increased FDG metabolism on the left lateral nasopharyngeal wall, considered physiological or inflammatory changes; please follow up with specialist examination.

7. Uneven thyroid density, increased FDG metabolism, suggesting possible inflammatory changes; please follow up with thyroid function tests and ultrasound. Reactive hyperplasia of bilateral 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.
