Metastatic paraganglioma and paraneoplastic-induced anemia in an adolescent: treatment with hepatic arterial chemoembolization.

Mediastinal paragangliomas are rare neoplasms in children. Anemia, as a paraneoplastic syndrome, has been described in adults with metastatic paraganglioma. The management of paraneoplastic anemia from metastatic paraganglioma has been problematic, with no reports in the literature describing successful treatment. This article describes a 17-year-old Jehovah's Witness with a mediastinal paraganglioma, hepatic metastases, and severe anemia. The patient and his family refused blood products and the anemia was refractory to erythropoietin and elemental iron therapy. Serial chemoembolization of the hepatic lesions resulted in resolution of the anemia, allowing subsequent debulking of the mediastinal paraganglioma.
