[Ultrasound tomography following surgery of tumors of the cerebellopontile angle].
After operations of the posterior fossa, ultrasonic tomography is a suitable noninvasive imaging procedure. After osteoclastic trepanation 45 patients were investigated with ultrasonic tomography. Below it were 18 patients with tumours of the cerebellopontine angle. A sector probe with a frequency of 3,5 MHz was used for the sonographical procedure. Ultrasonographical cross-sectional images were produced from occipital-retroauriculare or suboccipital. Solid processes have a definable echodense structure. Cystic processes and substantial defects of the brain are echopoor or echofree. Ultrasonic tomography allows an aimed application of CT controls.
