No thickening of the paranasal sinus mucosa was observed; sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; FDG uptake was increased bilaterally (SUVmax = 3.9); bilateral pharyngeal recesses were symmetrical; Eustachian tube openings were not narrowed; the infratemporal and pterygopalatine fossae were structurally normal; bilateral parapharyngeal spaces were clear; FDG uptake was not abnormal.
Bilateral palatine tonsils were full; FDG uptake was increased (SUVmax = 5.5).
Normal laryngopharyngeal morphology and structure were observed.
Normal thyroid morphology and size, with uniform density; FDG uptake was not abnormal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake was normal.
The thoracic cage was symmetrical.
An irregular soft tissue nodule, approximately 2.2 2.3 cm in size, was observed near the hilum of the right lower lobe, involving and trunculating the right lower lobe basal bronchus.
FDG uptake was increased in the lesion (SUVmax = 12.7), and scattered patchy consolidation was visible distally, measuring approximately 10.7 8.1 cm, with increased FDG uptake (SUVmax = 11).
Multiple small solid nodules were observed in both lungs, the largest located near the oblique fissure in the anteromedial basal segment of the left lower lobe, with a long diameter of approximately 0.5 cm; FDG uptake was normal.
The interlobular septa were thickened bilaterally, with scattered linear and patchy opacities.
Scattered air-containing cavities were observed in both lungs.
Multiple lymph nodes were observed in the hilum of both lungs, paratracheal region of the superior mediastinum, pretracheal region, posterior to the vena cava, aortic window, and subcarinal region.
The largest lymph node had a short diameter of approximately 1.5 cm, with increased FDG uptake (SUVmax = 13.0).
A small amount of pleural effusion was observed in the right pleural cavity.
The cardiac silhouette appeared normal, but pericardial effusion was present.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was not increased.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissure.
No abnormal density shadows were observed in the liver parenchyma; 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 significant masses, and FDG uptake was normal.
A roundish soft tissue density shadow, approximately 2.7 1.7 cm in size, was observed in the head of the pancreas and between the duodenum; no significant FDG uptake was observed.
The pancreatic body and tail showed no abnormalities in morphology, and no significant abnormal density shadows were observed in the parenchyma.
The main pancreatic duct was not widened, and no significant abnormal FDG uptake was observed.
The spleen showed no abnormalities in morphology or size, but calcifications were observed in the parenchyma; no abnormal FDG uptake was observed.
Both kidneys showed no abnormalities in morphology or size; a cystic lesion with a long diameter of approximately 3.0 cm was observed in the left kidney.
The renal pelvis, calyces, and ureters showed no widening, and no positive stones were observed within them.
Both adrenal glands were thickened, with increased FDG uptake (SUVmax = 8.3).
The stomach was poorly filled, with increased FDG uptake in parts of the gastric wall (SUVmax = 3.1).
Bowel preparation was poor; no obvious masses were observed in the intestinal wall, and FDG uptake was physiological.
The prostate showed no abnormalities in morphology or size, with a transverse diameter of approximately 3.6 cm; no significant abnormal density shadows were observed in the parenchyma, and no significant increase in FDG uptake was observed.
The bladder is adequately full, and no obvious positive stones are seen within it.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region, and FDG uptake is normal.
No obvious fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with slight flattening of the L1 vertebral body.
There is osteophyte formation at the marginal of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulging.
The right sacroiliac joint space is blurred.
Nodular FDG uptake is seen paravertebrally at the L2/3 intervertebral space level, with SUVmax=4.7.

Impression

1. a. Soft tissue nodules near the hilum of the right lower lobe with increased FDG metabolism, consistent with central lung cancer presentation, distal obstructive inflammation, and atelectasis; please correlate with clinical findings. b. Right hilar and mediastinal lymph node metastasis is highly probable; reactive hyperplasia of left hilar lymph nodes is possible. c. Bilateral adrenal gland enlargement with increased FDG uptake suggests possible hyperplasia; metastasis needs to be ruled out.

2. Multiple solid small nodules in both lungs, FDG metabolism normal; chronic inflammatory nodules are highly probable; follow-up CT scan recommended to rule out metastasis. A few linear and punctate lesions are also seen in both lungs, FDG metabolism normal. Interstitial changes in both lungs with scattered chronic inflammation and remnants. Emphysema in both lungs. Small amount of pleural effusion on the right side. Pericardial effusion. Partial arteriosclerosis (including coronary arteries).

3. a. Soft tissue density shadows in the head of the pancreas and between the duodenum, FDG uptake normal; physiological changes in the head of the pancreas are possible; space-occupying lesion needs to be ruled out; contrast-enhanced examination recommended. b. Splenic calcifications. Left renal cyst.

4. Increased FDG metabolism in part of the gastric wall, suggesting possible chronic inflammation; please follow up with gastroscopy.

5. Spinal degenerative changes. Mild wedge-shaped L1 vertebral body. L4/5 and L5/S1 intervertebral disc bulges. Blurred right sacroiliac joint space. Possible paravertebral inflammatory changes at the L2/3 intervertebral space level.

6. Bilateral deep lacunar infarcts, age-related brain; MRI follow-up is recommended to rule out occult lesions. Chronic inflammation of the nasopharynx and bilateral palatine tonsils.

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.
