| Description | Histological verification of CT or MRI suspected brain tumor is at prezent time necessary requirement for the indication of complex oncological treatment. Lesions affecting posterior fossa structures are less frequent target for stereotactic biopsy because of the concentration of vital structures in the limited space and more demanding approach. The choice of the approach is determined mainly by the lesion relationship to brainstem components. It is possible to use transfrontal approach along the long axis of the brainstem (lesions affecting mezencephalic and upper pontine region), transtentorial (lesions affecting cerebellar hemisphere and vermis) and direct transcerebellar (lesions of cerebellar hemisphere and pons, especially lateral). The paper analyses the use of the modified transcerebellar approach in 2 patients with lesions of unclear etiology affecting posterior fossa structures. In both patients transcerebellar stereotactic biopsy lead to diagnosis with decisive impact on further treatment strategy – indication of complex oncological treatment. |
