ABSTRACT
BACKGROUND:
The radiographic appearance of infectious intracranial aneurysms (IIAs) of infective endocarditis (IE) on magnetic resonance imaging (MRI) of brain is varied. We aimed to describe the IIA-specific MRI features in a series of patients with IIAs.METHODS:
Records of patients with active IE who had digital subtraction angiography (DSA) at a tertiary medical center from January 2011 to December 2016 were reviewed. MRIs performed prior to IIA treatment were reviewed for findings on susceptibility-weighted imaging (SWI), diffusion-weighted imaging, and T1 with and without contrast.RESULTS:
Of the 732 patients with IE, 53 (7%) had IIAs. Of these, 28 patients had an evaluable pre-treatment MRI, in whom 33 IIAs were imaged. MRI to DSA median time was 1 day (interquartile range = 1-5). On MRI, 12 (36%) IIAs had SWI lesion with contrast enhancement, 7 (21%) had cerebral microbleeds, 3 (11%) had sulcal SWI lesion, 2 (6%) IIAs had abscesses, 3 (9%) had intraparenchymal hemorrhage, 3 (9%) had subarachnoid hemorrhage, and 6 (18%) had ischemic stroke at the anatomical locations of IIAs. Four IIAs (12%) had no correlating MRI findings, though those patients had MRI without contrast.CONCLUSION:
The MRI features such as SWI lesion and contrast enhancement were the commonest MRI presentations associated with the presence of IIA.Palabras clave
