Coexistence of multiple metastatic brain tumors from thyroid carcinoma and cerebral aneurysms

: A 73-year-old woman was admitted with coexistence of multiple metastatic brain tumor and cerebral aneurysm. She has been operated on for a tumor of the thyroid gland 3 years before. Computed tomography (CT) scan revealed well-defined, homogeneously enhanced masses in the left frontal and right posterior temporal region. Right carotid angiography showed a tumor stain supplied by the branch of the fronto-polar artery. Left carotid angiography showed an aneurysm at the anterior communicating artery and a tumor stain supplied by the posterior temporal artery. Total removal of the bilateral tumor and aneurysmal neck clipping were performed simultaneously with bi-frontal craniotomy and right temporal craniotomy in April of 1988. Histology of tumor was papillary carcinoma. The surgical indication and treatment for patients with coexistence of multiple brain tumor and cerebral aneurysm were discussed.
