Case Report: Intracerebral Hemorrhage After γ-Knife Surgery for Metastatic Brain Tumor

AbstractThe authors report a case of a 69-year-old man with metastatic brain tumors who died of spontaneous intracerebral hemorrhage 3 days after γ-knife surgery. He had been suffering from lung cancer with multiple systemic metastasis. Preoperative magnetic resonance images showed two well-defined round lesions with intratumoral hemorrhage in the left frontal and right occipital lobe. There was no bleeding tendency in the hematological exam ination and the patient was normotensive. γ-Knife surgery was performed on both lesions in a single session. However, the patient died of massive intracerebral hemorrhage from the left frontal lesion 3 days after the surgery. There have been no previous reports of mortality resulting from spontaneo us intracerebral hemorrhage after γ-knife surgery in metastatic brain tumors documented in the literature. It is likely that the two events, γ-knife surgery and spontaneous intracerebral hemorrhage, occurred separately and were not associated. However, it is worth noting that there is a possibilit y of bleeding after γ-knife surgery, especially in a metastatic brain tumor with preexisting intratumoral hemorrhage as in our case.
