Ruptured Distal Middle Cerebral Artery Mycotic Aneurysm: A Rare, First Presentation of Infective Endocarditis

Area of Science:

• Neurology
• Neurosurgery
• Infectious Diseases

Background:

• Mycotic cerebral aneurysms are rare, inflammatory vascular lesions.
• They are associated with high mortality and morbidity, especially after rupture.
• Infective endocarditis is a known predisposing factor.

Observation:

• A patient presented with an incidentally discovered infective endocarditis.
• The endocarditis was associated with a ruptured distal middle cerebral artery mycotic aneurysm and an intracerebral hematoma.

Findings:

• Surgical intervention involved aneurysmectomy with clip ligation of the affected artery.
• Hematoma evacuation was performed concurrently.
• The patient achieved a favorable surgical outcome.

Implications:

• This case underscores the importance of early diagnosis and prompt surgical management of mycotic cerebral aneurysms.
• Effective treatment can mitigate the high morbidity and mortality associated with these lesions.
• Highlights the link between infective endocarditis and cerebrovascular complications.
