Comparison Between Transcranial Color-Coded Duplex Doppler and Contrast Enhanced Transcranial Color-Coded Duplex Doppler After Subarachnoid Aneurysmal Hemorrhage.

Background: Transcranial color-coded duplex Doppler (TCCD) is commonly used to detect and monitor vasospasm in subarachnoid aneurysmal hemorrhage (aSAH). However, contrast enhanced TCCD (CE-TCCD) may be more effective. The objective of this study was to compare the accuracy of TCCD and CE-TCCD in the detection of vasospasm.

Spontaneous Regression of a Third Ventricle Colloid Cyst.

Background: Colloid cysts represent 0.5%-1% of intracranial tumors and most commonly occur in the third ventricle near the Monro foramen. Although benign, if the lesion obstructs the foramen abruptly, sudden death may ensue.
