Posterior Inferior Cerebellar Artery Aneurysm: Surgical or EndovascularTreatment in a Case Report

Introduction: PICA aneurysms answer for 3% of all intracranial aneurysms. The patients generally present Hunt- Hess I or II and have intraventricular hemorrhage needing treatment. Case presentation: This is a case study about an elderly woman complaining about a sudden headache. She had an aneurysm in the distal segment of the PICA, which was treated by clipping. The woman progressed well despite her hydrocephalus. Discussion: Information about the aneurysm positioning and anatomy guided the therapeutic decisions. Age and clinical presentation are the most prominent factors in positive clinical evolution. An interdisciplinary team should choose between surgical and endovascular treatment.
