Key Points

To investigate the phenomenon of contrast extravasation following mechanical thrombectomy in a patient with an infected aneurysm.
Reported a case of a 77-year-old female with a history of infective endocarditis and stroke.
Performed mechanical thrombectomy followed by imaging with computed tomography (CT).
Evaluated factors contributing to contrast extravasation around the peripheral aneurysm.
Identified high-absorption areas around the aneurysm on CT post-thrombectomy.
Attributed findings to previous septic embolism associated with an existing infected aneurysm.
Highlighted the need for careful assessment regarding endovascular treatment necessity based on imaging outcomes.
