This case report details a 65-year-old male with a solitary pulmonary nodule and a Stanford type B descending thoracic aortic dissecting aneurysm. The rare, asymptomatic aortic condition impacted renal and splanchnic circulation.
Area of Science:
- Cardiology
- Thoracic Surgery
- Pulmonology
Background:
- A 65-year-old male with hypertension and chronic smoking history presented with respiratory symptoms.
- Initial chest radiograph revealed a left apical solitary pulmonary nodule (SPN) and descending thoracic aortic aneurysm.
Observation:
- Contrast-enhanced computed tomography (CECT) confirmed a malignant pulmonary lesion.
- CECT unexpectedly identified a Stanford type B descending thoracic aortic dissecting aneurysm with intramural hematoma.
Findings:
- The dissecting aneurysm compromised renal and splanchnic blood flow.
- This presentation of an asymptomatic dissecting aortic aneurysm is exceptionally rare, with fewer than 15 reported cases.
Implications:
- Highlights the importance of thorough imaging interpretation for incidental findings.
- Underscores the potential for co-existing, life-threatening conditions in patients with pulmonary nodules.
- Emphasizes the rarity and diagnostic challenge of asymptomatic Stanford type B aortic dissection.
