[Peroperative echography in neurosurgery. Its value and applications 10 years later]

Intraoperative ultrasound imaging has many advantages over other imaging methods. The authors present their experience from hundred patients over ultrasound scanning. A large iconography is exposed. Not only the intracerebral lesions such as gliomas or metastases but also abscess or cysts can be controlled or biopsied directly. Per-operative ultrasonography is interesting for spinal cord lesions and spinal traumas. Ten years from the first utilisation in neurosurgery, the method is always used, its cost is low and its practice is very easy.
