Paraganglioma with intracranial metastasis: a case report and review of the literature

Abstract

Paragangliomas are rare neuroendocrine tumors of neural crest origin. They are mostly benign, however; malignant tumors with aggressive behavior and distant metastasis can also occur. Intracranial involvement is extremely rare and has been sporadically reported in the literature. Here we report a case who presented with progressive neurologic deficits due to multiple intracranial lesions found to be metastasis from an occult retroperitoneal malignant paraganglioma.
