Nontraumatic Pure Acute Subdural Hematoma Caused by a Ruptured Cortical Middle Cerebral Artery Aneurysm: Case Report and Literature Review.

Nontraumatic or "spontaneous" acute subdural hematoma (SDH) is rare, and "pure" acute SDH without subarachnoid hemorrhage (SAH) due to aneurysmal rupture is extremely rare. We report a case of nontraumatic pure acute SDH caused by the rupture of a cortical middle cerebral artery (MCA) aneurysm. A 43-year-old man with no antecedents, except hypertension, presented to the emergency department with acute-onset moderate headache and nausea after swimming.

Vertebrobasilar infarction related to giant cell (temporal) arteritis: case report.

An 84-year-old male with a 3-month history of headache and elevated C-reactive protein levels was admitted for biopsy of the superficial temporal artery, which led to the diagnosis of giant cell arteritis (GCA). Two days after prednisolone therapy was initiated, the patient began to experience transient vertigo attacks. Two days later, dysarthria, left-sided hemiparesis, right abducens palsy, and horizontal nystagmus developed.

Outcomes of 24 patients with subarachnoid hemorrhage aged 80 years or older in a single center.

Objective: In the developed countries, elderly population is rapidly increasing, but outcomes of elderly patients with subarachnoid hemorrhage (SAH) remain unclear.

Patients And Methods: We retrospectively reviewed the medical records of non-traumatic SAH patients aged 80 years or older, who were hospitalized in a single center between 2000 and 2005.

Results: There were 24 patients (80-92 years old and 83% female), representing 8.

Focal dural arteriovenous fistula (DAVF) presenting with progressive cognitive impairment including amnesia and alexia.

A 75-year-old woman with a dural arteriovenous fistula (DAVF) presented with progressive cognitive impairment including amnesia and alexia. Neuroradiological studies showed a relatively confined DAVF lesion in the left temporal lobe. The patient did not have a history of trauma and did not complain of headache or tinnitus.

Delayed myelopathy induced by chronic compression in the rat spinal cord.

Cervical myelopathy is a common cause of neurological disability among the elderly; however, the exact mechanism for the insidious and progressive deterioration remains to be elucidated. To study the pathophysiology, we developed a simple experimental model reproducing the course. In rats, a thin sheet of expanding polymer was implanted microsurgically underneath the C5-C6 laminae.
