title: Case report: recurrent olfactory neuroblastoma nasal cavity in young boy refractory to chemotherapy with remission after radiotherapy and sparing of left eye.
abstract: Olfactory neuroblastomas make up about 3-5% of malignant intra-nasal tumors and originate from the olfactory neuroepithelium lining the roof of the nasal vault. There exist no optimum treatment guidelines from randomized data due to paucity of patients. Treatment options range from minimal surgery to extensive cranio-facial resections and adjuvant radiotherapy. In this case a tumor engulfing optic nerve and globe was safely treated by 3D-CRT with complete remission and relative sparing of the eye as well as late toxicities were avoided. 3D-CRT permits increased dose to tumor sparing critical areas and is a feasible option in centres without IMRT.
