A 50-year-old man experienced a recurrent hemorrhage in the ipsilateral hemisphere. A, CT image indicates the initial hemorrhage in the posterior portion of the body of the left lateral ventricle. B, CT image obtained 49 months later reveals a recurrent hemorrhage in the initial hemorrhagic site. C. Left anterior-posterior carotid artery angiogram obtained at baseline demonstrates no obvious anterior choroidal anastomosis from the internal carotid artery. Anterior-posterior (D) and lateral (E) views of the left vertebral angiogram obtained at baseline reveal the typical finding of lateral posterior choroidal anastomosis responsible for recurrent hemorrhage (black arrows).
