AB  - Intra-operative ultrasound (ioUS) is a very useful tool in surgery of spinal 
      lesions. Here we focus on modern ioUS to analyze its use for localisation, 
      visualisation and resection control in intramedullary cavernous malformations 
      (IMCM). A series of 35 consecutive intradural lesions were operated in our 
      hospital in a time period of 24 months using modern ioUS with a high frequency 
      7-15 MHz transducer and a true real time 3D transducer (both Phillips iU 22 
      ultrasound system). Six of those cases were treated with the admitting diagnosis 
      of a deep IMCM (two cervical, four thoracic lesions). IoUS images were performed 
      before and after the IMCM resection. Pre-operative and early postoperative MRI 
      images were performed in all patients. In all six IMCM cases a complete removal 
      of the lesion was achieved microsurgically resulting in an improved neurological 
      status of all patients. High frequency ioUS emerged to be a very useful tool 
      during surgery for localization and visualization. Excellent resection control by 
      ultrasound was possible in three cases. Minor resolution of true real time 3D 
      ioUS decreases the actual advantage of simultaneous reconstruction in two planes. 
      High frequency ioUS is the best choice for intra-operative imaging in deep IMCM 
      to localize and to visualize the lesion and to plan the perfect surgical 
      approach. Additionally, high frequency ioUS is suitable for intra-operative 
      resection control of the lesion in selected IMCM cases.
