The risk of surgery for left temporal lobe cavernous hemangioma is not particularly high, and the success rate of surgery can reach more than 95%, because the temporal lobe, in which there is a temporal pole, belongs to the non-functional area, which means that the removal of this part of the tissue does not affect the life and daily functions significantly, and in many cases, it can be properly removed. The temporal lobe is not very clear except for the superior temporal gyrus which has a clear corresponding function, so as long as the superior temporal gyrus is not damaged, there can be a relatively good treatment effect. Spongiform hemangioma can have a relatively good prognosis with preoperative radiotherapy and subsequent related treatment. However, the risk persists, and it is important to improve the preoperative examination to minimize the risk as much as possible in order to have a better therapeutic effect on the patient.
