Mass Lesions Stereotactics
In chapter 5, sub II we described seven situations in which a mass lesion should be diagnozed by means of a stereotactic biopsy. It is evident, that the availability of CT scan techniques has helped greatly in demonstrating such a situation, CT scan is in fact the only available means (with Magnetic Resonance imaging, which is currently in development) to assess the true position and extent of any mass lesion. Invading of surrounding tissues, such as brain parenchyma, skull base, and falx, is easily detected leading to better clinical diagnosis, although still presumptive without histological proof. In this chapter we will discuss tumor diagnostics, leaving infectious disease (although sometimes presenting as a tumor) for discussion in chapter 11, dealing with localization and aspiration stereotactics. With the assumption, that tumors amenable for stereotactic biopsy are deep seated, a chnical distinction can be made between eight patterns of growth. These patterns are:
skull base invading tumors.
