Abstract
A 55-year-old female presented with skull metastasis from breast cancer manifesting as acute epidural hematoma due to minor head trauma. She bumped her forehead against a steel pipe. Her consciousness became somnolent and left hemiparesis appeared. Skull X-ray films showed a large skull defect in the right frontal area. There was no evidence of skull fracture. Computed tomographic scans showed acute epidural hematoma bordering on large skull tumor. The right external carotid angiogram showed the tumor stain. It was assumed that direct injury of the vulnerable feeding artery of the tumor caused the hemorrhage. Removal of the tumor and hematoma was performed with no sequela. Skull metastasis associated with acute epidural hematoma after minor head trauma is a unique occurrence.
