Intraoperative cerebral ultrasound for third ventricle colloid cyst removal: case report.

PURPOSE: To assess the usefulness of intraoperative Ultrasound (ioUS) and Echo-Color-Doppler (ECD) for the surgical removal of a specific deep-sited lesion.

METHODS: Case report of a woman underwent surgery of a third ventricle colloid cyst removal.

RESULTS: The ioUS technique depicted the deep intraventricular lesion and all the anatomical structures surrounding the lesion; helping us defining the best trajectory for the safest surgical removal.

CONCLUSION: In our experience ioUS and ECD have demonstrated to be a reliable and useful intraoperative tool in neurosurgery, not only for superficial tumors but for deep intraventicular lesions as well.
