Case Reports
Levodopa-responsive hemiparkinsonism secondary to cystic expansion from a coiled cerebral aneurysm.
An 80-year-old woman with longstanding hemifacial spasm had a 1 cm × 1.5 cm internal carotid artery terminus aneurysm treated with endovascularly delivered bare metal coils. Follow-up imaging revealed an expansile perianeurysmal cyst that coincided with development of contralateral dopa-responsive hemiparkinsonism. This is the first report of perianeurysmal cyst expansion causing levodopa-responsive hemiparkinsonism.

Multipurpose ultrasound probes combined with ultra-mobile ultrasound instrumentation have the potential to increase the availability and use of ultrasound examinations in the assessment of atherosclerotic burden and cardiac disease. The aim of this study was to compare the agreement of a newly developed multipurpose probe to a standard linear carotid probe in detection of atherosclerosis of the precerebral arteries. ⋯ The multipurpose probe showed agreement with a standard linear probe in detecting atherosclerosis of the carotid arteries and has therefore the potential for use in both cardiac and precerebral ultrasound examinations.
