We read with great interest the article by Zhu and colleagues describing the findings of susceptibility weighted imaging (SWI) in eight patients. The authors of this paper highlighted the potential role of SWI in detecting ruptured basilar artery perforator aneurysms (BAPA) not detected on CT angiography.1 Another original finding described in the paper is a punctiform hyperintense signal at the center of the SWI capping corresponding to the BAPA.

We recently published a similar observation in a patient with infective endocarditis who presented with thunderclap headache.2 Our article highlighted the potential of SWI sequence to identify two ruptured intracranial infectious aneurysms located at the distal branches of the right calloso-marginal artery and of the …
