A Retrospective Analysis of the Role of Single-Session Gamma Knife Stereotactic Radiosurgery in Sporadic Vestibular Schwannomas with Tumor Volumes Greater Than 10 cm3: Is It Worth Stretching the Boundaries?

Objective: To evaluate the role of single-session Gamma Knife stereotactic radiosurgery (GK-SRS) in the treatment of vestibular schwannomas (VSs) with volumes of greater 10 cm3.

Methods: A retrospective analysis was performed of 103 patients treated with single-session GK-SRS between 1993 and 2011 with a mean follow-up of 6.2 years ± 4.

Predicting mortality after intracerebral hemorrhage: comparison of scoring systems and influence of withdrawal of care.

Objective: The Broderick system and the intracerebral hemorrhage (ICH) score are two systems for predicting 30-day mortality in patients with spontaneous ICH. No previous study has compared two ICH scoring systems in an independent patient cohort. Our purpose was to externally validate and directly compare these two systems and evaluate the effect of withdrawal of care on system performance.

Diagnosis and neuroimaging of acute stroke producing distal arm monoparesis.

Strokes which result in the isolated, pure motor weakness of an upper extremity are unusual and under-recognized cerebrovascular syndromes. Few reports in the literature describe the syndrome adequately or provide substantive clinical or anatomical correlation. Moreover, it may be misdiagnosed as a disorder of the peripheral nervous system because of the lack of pyramidal tract signs or the involvement of speech, the face, or lower limbs.
