Temporal lobe tumor

The incidence of temporal lobe tumors ranks second among tumors in the cerebral hemisphere, second only to the incidence of frontal lobe tumors. The most common tumors are gliomas, which account for about 17.96% of the total number of intracranial gliomas, followed by meningiomas, which account for about 5.42% of the total number of intracranial meningiomas. In addition, metastatic tumors often occur at this site. It is more common in adults, and the gender difference is not obvious. Temporal lobe function is very complicated, and the functions of some parts are not completely clear. The early course of temporal lobe tumors is usually without typical clinical symptoms, which is difficult to diagnose, especially those with tumors on the right side, most of which only show symptoms of increased intracranial pressure. Symptoms and signs rarely occur, so it was also clinically called ldquo; quiet area rdquo; or ldquo; dumb area rdquo ;, so early diagnosis is more difficult.
