Most asymptomatic patients with chronic subdural hematoma (CSDH) are followed conservatively but can require surgical treatment if the hematoma expands. We conducted a retrospective evaluation of the effect of Gorei-san on CSDH. This study included patients treated between April 2013 and March 2015.

We present a case that is most likely Lemierre's syndrome. A 19-year-old man presented to us with -common-cold-like symptoms, which he had had for 2 days, such as slight fever, general malaise, anorexia, sore throat, and headache. Eight days after the onset of these symptoms, he died of brain herniation due to cerebral venous thrombosis associated with micro-abscesses detected in pathological examination.

An 87-year-old woman presented with an atypical case of acute subdural hematoma (ASDH) manifesting as disturbance of consciousness and left hemiparesis. Computed tomography revealed a high density lentiform lesion in the right convexity, which was thought to be acute epidural hematoma preoperatively. Emergent decompressive craniotomy revealed an encapsulated solid fresh clot in the subdural space and a bleeding small cortical artery under the clot.

Progressive stroke is a serious problem due to the associated morbidity and mortality. Aspirin is recommended for acute ischemic stroke, but does not reduce the frequency of stroke progression. No standard treatment has been approved for the prevention of stroke progression.

Cold sensation and numbness have been reported as post-stroke sensory sequelae attributable to distal axonopathy, which is caused by chronic ischemia of diseased limbs resulting from dysfunction of vasomotor regulatory systems. Keishibukuryogan is a traditional herbal medicine used to treat symptoms of peripheral ischemia such as cold extremities. This study investigated clinical improvement and skin temperature in peripheral ischemia patients to determine the efficacy of keishibukuryogan in alleviating post-stroke cold sensation and numbness.

Objectives: Many studies have reported the association between mitral annular calcification (MAC) and stroke. MAC has been speculated to be a direct embolic source of stroke. Recently, the association between MAC and atherosclerosis in the coronary artery, aorta, and carotid artery has been reported.

Background: The indications and timing of treatment, as well as the best treatment method for traumatic central cord syndrome (CCS), remain controversial. The aims of this study are to determine the prognostic factors of traumatic CCS and to determine appropriate surgical indications.

Methods: We reviewed the clinical and radiological data of 47 patients with this syndrome.

Subdural hygroma is a frequent delayed complication of head trauma. Most hygromas are clinically 'silent' and a few cases have shown slow deterioration in the chronic stage. We report a case of subdural hygroma showing unique radiological findings and rapid deterioration.

Stroke is the third leading cause of death in the adult population. Numerous neuroprotective agents and procedures have been developed and a new wave of therapies is now on the horizon with the potential to minimize ischemic brain damage. On the other hand, surgical treatment has also played an important role in the treatment of stroke.

The delayed cerebral vasoconstriction known as cerebral vasospasm remains a significant cause of permanent neurological deficit and death following aneurysmal subarachnoid hemorrhage despite the best current medical therapies. The mechanism of cerebral vasospasm remains unknown. Several new drugs have been tested in animal models of subarachnoid hemorrhage, and these experimental studies have contributed to a better understanding of the potential mechanisms that lead to cerebral vasospasm.

Perimesencephalic nonaneurysmal subarachnoid hemorrhage (SAH) is a distinct type of hemorrhage with a characteristic bleeding pattern and an excellent clinical outcome. The cause of this benign form of SAH remains unknown. The authors report on two cases of perimesencephalic nonaneurysmal SAH in which a small bulge on the basilar artery (BA) was demonstrated on three-dimensional rotational angiography studies.

Object: Cerebral vasospasm remains a devastating medical complication of aneurysmal subarachnoid hemorrhage (SAH). Reactive oxygen species and subsequent lipid peroxidation are reported to participate in the causes of cerebral vasospasm. This clinical study was performed to investigate the relationships between levels of lipid peroxides in cerebrospinal fluid (CSF) and both delayed cerebral vasospasm and clinical outcome after SAH.

Objective And Importance: Aneurysms arising from the ophthalmic artery are extremely rare, compared with carotid-ophthalmic aneurysms arising from the wall of the internal carotid artery. We present a very unusual type of aneurysm arising from the ophthalmic artery itself.

Clinical Presentation: A 54-year-old man presented with a sudden onset of headache and was transferred to a local hospital.
