Very rarely, spinal subarachnoid hemorrhage (SSAH) can occur without any direct spinal injury in patients with traumatic intracranial SAH. A-59-year-old male with traumatic intracranial subarachnoid hemorrhage (SAH) presented with pain and numbness in his buttock and thigh two days after trauma. Pain and numbness rapidly worsened and perianal numbness and voiding difficulty began on the next da...

BACKGROUND AND PURPOSE Many patients with aneurysmal subarachnoid hemorrhage (SAH) with intraparenchymal extension develop early hematoma expansion, which is not explained by aneurysmal rerupture in half of cases. In patients with primary intracerebral hemorrhage, the computed tomography angiography (CTA) spot sign predicts hematoma expansion and poor outcome. We conducted a 2-center prospectiv...

Cerebral amyloid angiopathy is a pathologic condition characterized by the deposition of amyloid in the walls of small vessels in the cerebral cortex and meninges. Intracerebral hemorrhage is common in persons with this condition, but pure subarachnoid or subdural hemorrhage is rarely seen. Recently, the existence of two types of amyloid proteins related to cerebral amyloid angiopathy, beta pro...

A 49-year-old white male presented with a pseudo-subarachnoid hemorrhage and diffuse brain edema. Neuroimaging showed brain edema causing the unusual findings of a pseudo-subarachnoid hemorrhage and bilateral occipital lobe infarcts following herniation and compression of the posterior cerebral arteries. An enlarged corpus callosum was noted which led to a brain biopsy and a diagnosis of glioma...

We present a case of subarachnoid hemorrhage attributed to rupture of an aneurysm 18 months after endovascular occlusion. The aneurysm was diagnosed after the patient had a seizure; however, there was no evidence of subarachnoid hemorrhage. Angiography at 6 months revealed a totally occluded aneurysm. This case illustrates that the long-term results of endovascular occlusion remain uncertain.

AIM Factors affecting the development of postoperative hydrocephalus patients who underwent surgery after aneurysmal subarachnoid hemorrhage were retrospectively assessed. MATERIAL AND METHODS 201 cases, who underwent aneurysm surgery in our clinic after subarachnoid hemorrhage between 2008 and 2013, were retrospectively assessed. Twenty-one cases with hydrocephalus development were retrospec...

Subarachnoid hemorrhage has a much higher intensity in magnetic resonance (MR) images with the passage of time. Acute subarachnoid hemorrhage is difficult to see; within 1 week its appearance has become intensified on T1-weighted images. Different concentrations of blood and lysed red blood cells in cerebrospinal fluid (CSF) were examined spectroscopically but did not significantly alter T1 and...
