Mycotic aneurysm: A rare and dreaded complication of infective endocarditis

Abstract

Mycotic cerebral aneurysm is a rare and potentially fatal complication of infective endocarditis. A young man was diagnosed with culture negative infective endocarditis of mitral valve with cerebral aneurysm. The patient was started on conservative management, but he died owing to intracerebral haemorrhage. In the absence of large randomised trials, there is a lack of consensus regarding the management of unruptured aneurysms. Since mycotic aneurysms are known to resolve or decrease in size with antimicrobial therapy, several institutions advice the conservative approach. A few case reports like the present case have shown that the risk of aneurysmal rupture and death is considerably high with the conservative approach. Endovascular therapy has shown to reduce the mortality in this subgroup. These patients should be managed aggressively with endovascular or surgical procedure along with antimicrobial therapy.
