The appropriate strategy for treating multiple malignant brain tumors has not been well established. We discuss the indications and surgical considerations of multiple craniotomies in the same surgical session, and present three such cases. A 41-year-old woman (case 1) and a 65-year-old man (case 2), both presented with two metastatic brain lesions, one in each hemisphere. The third case was a 65-year-old woman with multiple recurrent atypical meningiomas, who underwent surgical removal in two stages. In the first surgery, only the superior sagittal sinus lesion was excised. Then in the second surgery, multiple disseminated bilateral convexity tumors were excised through a craniotomy on each side. All cases had a remarkable neurological improvement immediately after surgery. We suggest that the indications for surgical removal of multiple brain tumors with two or more craniotomies in the same surgical session are:1) progressing neurological symptoms, 2) tumors with a maximum diameter more than 2 cm, 3) resistance to radiation and/or chemotherapy, 4) ability to tolerate the scheduled surgical time, 5) vital prognosis anticipated to be more than 3 months, 6) expectation of significant neurological improvement, and 7) single-session surgery not carrying more risk than multiple surgeries.
