Dynamic and three-dimensional transcranial ultrasonography of an arachnoid cyst in the cerebral convexity. Technical note.
TLDR
Evidence of the high resolution and good reproducibility of 3D TC methods is represented and may be used to improve management and therapeutic strategies for patients with space-occupying brain lesions in selected cases.Abstract:
✓ Structural imaging of the brain, such as cerebral computerized tomography (CT) and magnetic resonance (MR) imaging, is state-of-the-art. Dynamic transcranial (dTC) ultrasonography and three-dimensional (3D) transcranial color-coded duplex (TCC) ultrasonography are complementary, noninvasive procedures with the capacity for real-time imaging, which may aid in the temporary management of space-occupying lesions. A 16-year-old woman presented with recurrent tension-type headaches. A space-occupying arachnoid cyst in the cerebral convexity was demonstrated on MR images. The patient underwent an examination for raised intracranial pressure, which was performed using a standard color-coded duplex ultrasonography system attached to a personal computer—based system for 3D data acquisition. Transcranial ultrasonography was used to identify the outer arachnoid membrane of the cyst, which undulated freely in response to rotation of the patient's head (headshake maneuver). Three-dimensional data sets were acquired ...read more

Potential and Limitations of Transcranial Color-Coded Sonography in Stroke Patients
TL;DR: Transcranial color-coded duplex sonography is a noninvasive bedside method that provides rapid and reliable data regarding stroke subtype and mechanism immediately after onset and window failure is a serious limitation of this method.
