Diagnosis is often challenging. Neurogenic heart syndrome often complicates subarachnoid hemorrhage. Consequently, their rupture causes subarachnoid hemorrhage (SAH). Berry aneurysm rupture is the second most common cause following trauma. It is the bleeding into the subarachnoid space which is a space between arachnid and pia mater. Aneurysms are abnormal localized dilatations in arteries. Case 3: SAH due to ruptured left MCA aneurysm, Case 4: ruptured PCom aneurysm and SAH, SDH and jet hematoma, autosomal dominant polycystic kidney disease, intracranial atherosclerotic disease (ICAD), Alberta stroke program early CT score (ASPECTS), thrombolysis in cerebral infarction (TICI), modified treatment in cerebral infarction (mTICI), posterior inferior cerebellar artery infarct, hemorrhagic transformation of an ischemic infarct, cerebral intraparenchymal hyperattenuations post thrombectomy, perimesencephalic subarachnoid hemorrhage (PMSAH), autonomic disturbances (nausea/vomiting, chills and palpitations), focal neurology (sensory loss, weakness, memory loss, language difficulties), although a genetic component is likely as incidence in first-degree relatives of affected patients is increased, an unruptured aneurysm appears as a thin-walled, shiny red outpouching usually measuring a few milimeters to 3 cm in diameter, rupture usually occurs at the apex of the sac, the arterial wall adjacent to the neck of the sac usually shows thickening of the intima and thinning out of the media as the neck is approached, the sac itself is usually made up of thickened intima with the adventitia of the parent artery surrounding the sac. Subarachnoid hemorrhage (SAH) is bleeding into the subarachnoid space—the area between the arachnoid membrane and the pia mater surrounding the brain. Several risk factors such as smoking, hypertension, and excessive alcohol intake are associated with subarachnoid hemorrhage (summary by Krischek and Inoue, 2006).
