Two cases of subdural hematoma secondary to metastatic dural carcinomatoses are reported herein. In the first case, the subdural hematoma was assumed to be the result of obstruction of the dural veins by tumor cells and from the subsequent bleeding from the capillaries in the inner areolar layer of the dura. Furthermore, the elevation of intracranial pressure seemed to be caused by the occlusion of the dural sinus by the tumor cells. In the second case, a coagulation defect or DIC played significant role in the development of the subdural hematoma. Also, bleeding from the immature outer membrane of the hematoma caused a large amount of intermittent subdural hemorrhage. The relevant literature about subdural hematoma due to dural metastasis of malignant tumors was reviewed, and the mechanism of the hemorrhagic phenomenon was discussed.
