Case 29A1,2 ---- Coronal sections of the brain display the presence of a necrotic space occupying lesion extending from the tip of the right frontal pole posteriorly to the level of the mammillary bodies. The lesion is concentrated in the orbital gyri of the frontal lobe but also involves the lower and middle frontal gyri anteriorly. The tumor extends into the right hemisphere for a short distance in the region of the genu of the corpus callosum and the anterior horn of the right lateral ventricle. The tumor infiltrates and totally replaces the corpus striatum anterior to the anterior commissure and also extends into the region of the left inferior claustrum and insula.
