A recent instance of the operative removal of a large bilateral parasagittal meningioma with the conicident resection of a considerable portion of the middle and posterior part of the superior longitudinal sinus has been thought sufficiently important to warrant reporting, not only because of the lack of untoward effects on the patient but also because of the scarcity of similar incidents in the literature. Cushing and Eisenhardt,1 in their recent monograph on meningiomas, made the following statement: "We know of only one instance in which a bilateral parasagittal meningioma along with involved sinus has been surgically removed from the rolandic area with no postoperative disability." This case was reported by David, Bissery and Brun2 in 1934. Recently, Rowe3 has reported another case of successful resection of the longitudinal sinus in the middle and posterior regions.
It has long been known that parasagittal meningiomas invade the sinus.4
