MRSA Mycotic Aneurysm Associated with Infected Pacemaker Leads

Key Result

A 75-year-old woman with persistent MRSA bacteremia and infected AICD leads was diagnosed with a descending thoracic mycotic aneurysm using FDG-PET and CTA.

Key Points

• This report highlights the relationship between MRSA bacteremia and the development of a mycotic aneurysm linked to cardiac devices.
• Case examination of a 75-year-old woman with persistent MRSA bacteremia.
• Identification of the mycotic aneurysm using FDG-PET and CTA imaging.
• Assessment of the infection due to MRSA infected leads from an automatic-implantable cardiac defibrillator.
• The patient was found to have a descending thoracic mycotic aneurysm as a complication of MRSA infection.
• The aneurysm was effectively characterized through imaging techniques, confirming its association with underlying atherosclerosis.
• The automatic-implantable cardiac defibrillator required explantation due to the infected leads.
