Low NIHSS score large vessel occlusion caused by infective endocarditis treated with thrombectomy.

Objectives: Large vessel occlusion (LVO)-related acute ischemic stroke due to infective endocarditis (IE) is a rare condition. At onset, most patients are severely ill, whereas on rare occasion, they develop mild neurological symptoms. As far as we are aware, this is the first report of IE related internal carotid artery (ICA) occlusion with low National Institutes of Health Stroke Scale (NIHSS) (<6) score treated with endovascular thrombectomy.

Hydrocephalus Resulting from Late-Onset Aqueductal Membranous Occlusion: A Case Report and Review of the Literature.

Background: Late-onset aqueductal membranous occlusion (LAMO) is 1 of the few causes of noncommunicating hydrocephalus. Here, we report a case of LAMO and review the associated literature.

Case Description: A 36-year-old man had complained of headache and loss of consciousness.

Stereotactic radiosurgery for atypical and anaplastic meningiomas.

Atypical and anaplastic meningiomas frequently recur in the relatively short-term after surgery. We have followed such postoperative cases by short-interval repeated MRI and have performed stereotactic radiosurgery (SRS) for progressive tumors as a salvage therapy. The objective of this report was assessment of the degree of tumor control, the risk of complications, and the presence of variables that predict outcome in patients treated with SRS for high-grade meningiomas.

Initial experiences of palliative stereotactic radiosurgery for recurrent brain lymphomas.

In Kyoto University Hospital, stereotactic radiosurgery (SRS) has been performed for its rapid palliative effect in patients with recurrent primary central nervous system lymphoma (PCNSL), often in combination with salvage chemotherapy. In the present study, the treatment outcome and toxicity of SRS for recurrent PCNSL was retrospectively evaluated. Between March 1998 and June 2004, 17 histologically proven recurrent PCNSLs in nine patients were treated with linac-based stereotactic radiosurgery.

Quantitative analysis of topoisomerase IIalpha to rapidly evaluate cell proliferation in brain tumors.

Immunohistochemical cell proliferation analyses have come into wide use for evaluation of tumor malignancy. Topoisomerase IIalpha (topo IIalpha), an essential nuclear enzyme, has been known to have cell cycle coupled expression. We here show the usefulness of quantitative analysis of topo IIalpha mRNA to rapidly evaluate cell proliferation in brain tumors.

A "mouse in a trap" method for cerebral protection during carotid stenting: Technical note.

Carotid artery angioplasty and stenting (CAS) is now used as an alternative to surgical endarterectomy. The introduction of cerebral protection systems during stenting has improved carotid artery stenosis treatment, with less periprocedural complications. A "mouse in a trap" method was conceived and used in three patients.

A recurrent intradural cervical neurenteric cyst operated on using an anterior approach: a case report.

The neurenteric cyst is an uncommon congenital lesion. In most reported cases, it has been operated on via a posterior approach using a laminectomy, despite the fact that the cyst is usually located ventral to the spinal cord. Reports have shown that early postoperative results have been good with the posterior approach, but very few studies of the long-term postoperative recurrence of neurenteric cysts have been conducted.
