Removal of Double Cavernous Angioma of the Frontal Lobe using a Three-Dimensional Printed Model: A Case Report

Cerebral cavernous angiomas are vascular anomalies with dilated spaces. We report the case of rare double cavernous angiomas causing higher brain dysfunction. A 74-year-old man exhibited cognitive dysfunction. Magnetic resonance imaging showed two tumors with hemorrhage in the left frontal lobe. Preoperative diagnosis was hemorrhage caused by cavernous angiomas. A 3D model of the double cavernous angioma was made to confirm their association with cortical veins and tumors. Tumors were removed using a single small corticotomy. This is the first report of a rare double cavernous angioma and the 3D printed model facilitated removal of the tumors.
