Abstract
Olfactory neuroblastma is a rare kind of malignant tumor originating in the olfactory epithelium of the nasal cavity. We report here a clinical case of olfactory neuroblastoma. A 52-year-old man presented with headache and vomiting. CT scan and MRI showed a large tumor in the right ethmoid sinus extending into the frontal base. The tumor was resected subtotally, and radiation therapy at a dose of 60 Gy was undertaken. However, a follow-up MRI two years after surgery showed metastasis to the left cervical lymph nodes. The patient was treated with radiation and chemotherapy, which resulted in a reduction in the size of the metastasized tumor.
