Popis: The introduction of magnetic resonance imaging (MRI) has revolutionized the diagnosis and treatment of cavernous malformations. The MRI characteristics of these lesions are in most cases pathognomonic and the diagnosis of cavernous malformation can frequently be established on the basis of neuroimaging findings alone, without the need for pathological confirmation. MRI also precisely demonstrates the location of the lesion and defines its relationship to surrounding structures, providing essential data for preoperative evaluation and surgical planning. The role of MR imaging in the immediate postoperative setting remains less clear, as the extent of the surgical resection and correspondingly, the presence of residual cavernous malformation tissue is frequently difficult to determine. In the postoperative setting, long-term follow up is generally required to confirm a curative resection.
