Multiple recurrences of unknown primary tumor in a meningioma: A case report.

Metastasis of a systemic tumor into a primary brain tumor has been rarely reported in the literature. These metastases could be seen mostly in meningiomas and in less frequently in the other intracranial tumors. Carcinoma of an unknown primary site (CUP) metastasizing into an intracranial meningioma is not a common occasion. According to the best of our knowledge, in this report, we present the first case with multiple recurrent CUP, which metastasized to intracranial meningioma, reported in the literature. The whole body was investigated with FDG PET/CT and biomarkers of the most common carcinomas for primary cancer. However, these tests showed no primary affected region. Despite all adjuvant therapies, the tumor had multiple recurrences. Such cases are still a challenge to offer optimal management.
