Computed tomography (CT) effectively diagnoses infected aortic aneurysms by identifying key features like perianeurysmal fluid and osteomyelitis, often negating the need for aortography.

Area of Science:

  • Radiology
  • Vascular Surgery
  • Infectious Diseases

Background:

  • Infected (mycotic) aortic aneurysms are rare but life-threatening conditions.
  • Early and accurate diagnosis is crucial for effective management and improved patient outcomes.

Observation:

  • This study details the diagnostic utility of computed tomography (CT) in three patients with mycotic aortic aneurysms.
  • CT imaging was the primary diagnostic tool used for all patients.

Findings:

  • CT revealed characteristic features including saccular aneurysms with irregular lumens, perianeurysmal fluid, gas, or hematoma.
  • Adjacent osteomyelitis of vertebral bodies and disrupted intimal calcification were noted in two cases.
  • Rapid aneurysm development was observed in a patient with sepsis, highlighting the aggressive nature of the condition.

Implications:

  • CT provides substantial benefit in identifying and characterizing infected aortic aneurysms.
  • Specific CT findings can strongly suggest the diagnosis, potentially obviating the need for invasive aortography.
  • Enhanced CT imaging improves diagnostic accuracy for mycotic aortic aneurysms, guiding timely surgical and medical interventions.
