[Malignant paraganglioma with intracranial metastasis: a case report].

We report a case of malignant paraganglioma with intracranial metastasis. A 26-year-old man presented with leg pain. On admission a metastatic bone tumor was found. General examination revealed metastatic lesions in the lung, liver, orbits, ethmoid sinus, anterior mediastinum, and brain. An MRI of the head showed multiple lesions in the skull bone and intracranial space. A biopsy was performed on the right temporal tumor, resulting in a diagnosis of malignant paraganglioma. The tumor origin could not be determined. The tumor resection was not indicated because of multiple metastasis. Both chemotherapy and radiotherapy were given to the patient, but a satisfactory outcome was not obtained.
