Left perirolandic metastatic brain cancer

The most common type of brain tumor in adults is metastatic brain tumors, with an incidence 3 to 14 per 100,000 people per year. Approximately 10% to 20% of these metastatic brain tumors occur in eloquent locations, which include primary motor, somatosensory, speech, and/or visual cortices. The general management of large, symptomatic metastatic brain tumors is surgery followed by radiation therapy. However, lesions in eloquent regions are surgically more challenging, and therefore typically undergo radiation therapy to minimize the risk of surgically induced morbidity. Radiation without surgical therapy, however, does little to improve symptomatic mass effect in the immediate period. In this chapter, we present a case of a patient with a dominant hemisphere perirolandic metastatic brain tumor.
