The role of the intraoperative ultrasonography in low-grade gliomas: Case report

Abstract

Objective: Use of intraoperative ultrasound for localizing tumors and determining the extent of resection.
Materials and methods: We report two patients diagnosed with brain tumors that underwent intraoperative ultrasonoghraphy in localizing and defining the borders of tumors and assessing the extent of their resection.
Discussions: Intraoperative ultrasound brain scanning is extremely useful to detect the cerebral lesion, the relationships with the nearby structures, the estimation of vascularization, the grade of resection and other associated lesions. The tumor image is different from the normal anatomical CNS structures, and some features like soft or hard tissue, cystic or necrotic areas can be visualized. 
Conclusion: Cerebral intraoperative ultrasound is a benefit for the surgical act, thus being the neurosurgeon’s “deep-seated eye”.
