Abstract

Esthesioneuroblastoma is a rare neuroectodermal tumor of the nasal vault with an aggressive biological behavior that is characterized by local recurrence, atypical distant metastasis, and poor long-term prognosis. The treatment regimen consists of surgical resection, radiation therapy, and chemotherapy in various, mainly stage-dependent, combinations. We report two cases of primary metastatic and locally recurrent disease, which were treated with computed tomography-guided interstitial high-dose-rate brachytherapy in palliative and curative intent, respectively. Computed tomography-guided interstitial high-dose-rate brachytherapy should be considered as a feasible treatment option for advanced esthesioneuroblastoma
