Background. The goal of the current study was to assess the usefulness, reliability and safety of the image guided stereotactic biopsy of intra-axial brain tumours. Methods. The study was conducted within a time frame of one year. 20 patients - 14 males and 6 females (median age 63.5 years) were included. Computerized tomography (CT) - guided stereotactic biopsies were performed by a single stereotactic neurosurgeon. A modified Riechert Stereotactic System (MHT Medical High Tech) and a workstation for multiplanar trajectory planning (Amira) were used. Biopsies were done with small forceps and 10-15 samples were collected for histological analysis. During the operations also touch imprints and crush smears of the specimens were examined by the cytopathologist. Correct place of the biopsy and any detectable bleeding were analyzed by post-op CT scan. Descriptive statistic methods were used and results were compared with the data from the literature. Results. Overall treatment morbidity was limited to one patient (5 %), there was no mortality. A conclusive tissue diagnosis could be achieved in 19 out of 20 patients (95 %). There were 3 glioblastomas, 3 anaplastic astrocitomas, 5 astrocitomas, 1 inflammation, 2 lymphomas, and 2 malignant tumours - not further classified and 3 metastasis. All patients had post biopsy CT scan to check for haemorrhage (none occurred). Conclusions MHT Stereotactic system and Amira multiplanar image guided trajectory planning software are reliable tools enabling trained stereotactic neurosurgeon to obtain tissue diagnosis in almost every case with very little morbidity.
