However, Riskaer2 pointed out that careful examination of their report reveals that the three tumors in question did not originate in the septum pellucidum but were tumors of the frontal lobe that merely invaded the septum. Riskaer reported on two astrocytomas of the septum pellucidum for which operations were done successfully in 1941.
