Subarachnoid hemorrhage in isolated posterior inferior cerebellar artery dissection: Literature review and report of 2 cases

ConclusionPICAD with ischemic stroke is likely under-diagnosed due to the following reasons; 1) patients present with neurological deficits that are non-specific and mild, 2) DSA, which is a gold standard of diagnosing PICAD is not regularly performed in these patients, 3) lack of predisposing factors associated with PICAD in some patients. The mild and non-specific clinical presentation in young adults with PICAD with ischemia probably due to their ability to compensate better given low incidences of other comorbidities. Further investigation regarding the underlying etiology of isolated PICAD, association of proximal PICAD to ischemia and distal PICAD to SAH as well as use of SWI in detecting PICAD is recommended.
