The olfactory neuroblastoma (ONB) is a rare malignant tumor that arises in the nasal cavity and paranasal sinuses. most common treatment craniofacial resection, but recently endoscopic resection has been used as an initial to reduce complications. In addition, depending on stage of disease, radiation therapy or chemotherapy can be performed before after surgery. ONB also recur, showing two patterns recurrence: local recurrence distant metastasis cervical lymph nodes lungs. Local usually treated with craniotomy, this invasive method cause various Therefore, non-invasive methods such stereotactic are now being considered. authors report recurred case successfully Gamma knife radiosurgery without patient showed delayed bilateral node suspected recurrent intracranial invasion treatment.
