Aneurysms involving the peripheral portion of the superior cerebellar artery (SCA) are rare and usually present with subarachnoid hemorrhage (SAH) or, less commonly, fourth nerve dysfunction. We reported the case of a 81-year-old Caucasian woman evaluated at our Emergency Department due to acute cerebellar symptoms, with ischemic stroke involving lamina quadrigemina and quadrangular lobule of the ipsilateral cerebellar hemisphere due to partial thrombosis of distal superior cerebellar artery aneurism, diagnosed with brain magnetic resonance. The patient was surgically treated with complete resolution of neurological signs. Even if presentation with stroke is rare (only few case reports are reported in literature), peripheral SCA aneurysms presenting with ischemia should be recognized to prevent SAH from an undiagnosed lesion.
