title: Ultrasound guided needle biopsy of brain tumors using an automatic sampling instrument.
abstract: All ultrasound (US) guided needle biopsies of brain tumors performed during an 8-year period were reviewed. Tissue samples were obtained in 112 of 115 biopsy procedures, and a histologic diagnosis was established in 99 cases (88.4%). The rate of major complications was 8.0%. The mortality is similar as in reports on stereotactic and CT-guided biopsy procedures while the morbidity is higher in our material. There are no large series available on US guided intracranial biopsy with adequate reports of complications. A modified biopsy technique is introduced here using a cutting needle and an automatic sampling instrument. The modified technique, which has been used in all cases since 1985, yielded diagnostic material in 91.5%. This method consistently provides a tissue core which is essential for a confident histopathologic diagnosis.
