OBJECTIVE Symptomatic cerebral vasospasm is a major cause of disability and death in patients with aneurysmal subarachnoid hemorrhage. The purpose of this study was to determine the efficacy of intra-arterial infusion (IAF) of fasudil hydrochloride for symptomatic vasospasm in terms of neurological improvement and the angiographic features of cerebral(More)
We study the Mathias-Prikry and Laver-Prikry forc-ings associated with filters on ω. We give a combinatorial characterization of Martin's number for these forcing notions and present a general scheme for analyzing preservation properties for them. In particular, we give a combinatorial characterization of those filters for which the Mathias-Prikry forcing(More)
Direct surgical intervention to treat ruptured basilar tip aneurysms in patients with moyamoya disease has rarely been attempted, and patients who have undergone such treatment have not fully recovered. We review six cases of surgically treated ruptured basilar tip aneurysm associated with moyamoya disease, including our own case to illustrate aspects of(More)
A 67-year-old man presented with persistent penis and scrotum pain due to S-2 and S-3 radiculopathy caused by a sacral perineural cyst. The cyst was treated with microsurgical partial cyst removal and cyst wall imbrication, together with closure of the point through which cerebrospinal fluid (CSF) flowed from the subarachnoid space into the cyst cavity. His(More)
BACKGROUND Intracranial enterogenous cysts are rare and occur mainly in the posterior fossa. These cysts are usually extra-axial, midline, anterior to the brainstem, or at the cerebellopontine angle. Intracranial intra-axial enterogenous cysts are extremely rare. We report a case of an intra-axial cerebellar enterogenous cyst in which diagnosis was(More)
A 75-year-old man with Lhermitte-Duclos Disease (LDD) manifesting as progressive headache is presented. Magnetic resonance imaging demonstrated a right cerebellar mass lesion with the characteristic "tiger-striped appearance". A mild mass effect was evident at the medulla oblongata, accompanied by inferior displacement of the right cerebellar tonsil. Thus,(More)
A 52-year-old man fell from standing and a computed tomography (CT) scan revealed traumatic intracerebral haematoma and subarachnoid haemorrhage in the temporal cortex. He was treated without surgery and discharged. On day 30 after the accident, he had no neurological deficit. On day 37 he complained of headache and urinary incontinence, and on day 39 he(More)
