Left ventricular outflow tract (LVOT) vegetations and spontaneous obliteration of a large ruptured intracranial mycotic aneurysm in a case of infective endocarditis.

A 10-year-old girl with mild aortic regurgitation presented with cerebral infarction. Two-dimensional echocardiography showed vegetations on the septal wall of the left ventricular outflow tract without involvement of the aortic valve itself. After successful antibiotic treatment the patient developed an intra-cranial haemorrhage due to rupture of a large intracranial mycotic aneurysm. Consent for surgical treatment of the mycotic aneurysm was not obtained. Twelve months later repeat angiography showed that the aneurysm had undergone spontaneous obliteration.
