Comparing the role of different treatment modalities in locoregionally advanced olfactory neuroblastoma: The 20-year clinical experience of a single institution. Esthesioneuroblastoma (es-thee-zee-o-noo-row-blas-TOE-muh) is a rare type of cancer that starts in the upper part of the inside of the nose, known as the nasal cavity.

Understanding the Context

Esthesioneuroblastoma also is called olfactory neuroblastoma. This cancer usually affects adults. But it can occur at any age ... Chordomas, chondrosarcomas, sinonasal carcinomas and olfactory neuroblastomas are more likely than other types of skull base tumors to spread throughout the body.

Key Insights

Whether or not skull base tumors spread, and how quickly they do so, depends on the type and grade of the tumor. High-grade cancerous tumors are more aggressive. What causes olfactory hallucinations? An olfactory hallucination, known as phantosmia, makes you detect smells that aren't in your environment. The odors you notice in phantosmia are different from person to person and may be foul or pleasant.

Final Thoughts

You may notice the smells in one or both nostrils. Expanding the understanding of what causes anosmia The long-standing belief within the medical community is that the primary cause of anosmia is damage to olfactory sensory neurons. The fine nerve fibers, which travel through bone to connect the olfactory bulb to the nasal epithelium, are vulnerable to trauma and viral infections. Olfactory dysfunction.
