Perimesencephalic subarachnoid hemorrhage (PM-SAH) refers to intracranial hemorrhage located in the perimesencephalic cistern. The etiology remains mainly unclear, although venous leakage or rupture has been postulated. We report an interesting case of a 57-year-old healthy man who presented initially with PM-SAH with worsening of subcortical lesions on follow-up neuroimaging. Histopathological examination demonstrated cerebral amyloid angiopathy with perivascular inflammation.
