Carcinomata, practically speaking, are found in the brain only asmetastatic growths arising from primary cancer in the body organs,breast, etc., or through direct invasion by extension from orbital or othercranial and facial carcinomatous growths. They are also practicallyconfined to the second half of life. Uncontrolled by the soft tissue ofthe encephalon, carcinomata rapidly invade the brain, forming ill- TU3I0ES OF THE BRAIN. 259 defined, nodular, rarely encapsulated, very vascular, and practically in-operable tumors. When arising secondarily from cancer in the bodyorgans, especially those in the thorax, carcinoma of the brain locatesby preference in the neighborhood of the great vessels of the base. Inother instances it springs from the choroid structures and the epitheliallining of the ventricles, or from the dura and pia mater. Cysts form tumors in the brain with comparative frequency.
