IN A REPORT from this laboratory, non-neoplastic lesions of the mesencephalon and aqueduct of Sylvius were discussed.1 In the present communication are presented four cases of neoplasms restricted to the mesencephalon. Interest in this area has increased in recent years, especially after the work of Magoun2 and coworkers. The literature is reviewed for purposes of comparison, consideration being limited to cases in which sufficient clinical and pathologic data are available.3 Cases of extracerebral compressive lesions, multiple neoplasms, or lesions extending into neighboring structures are excluded.
