What is this Condition?

Symptoms

Unilateral, progressive, persistent nasal obstruction
Recurrent, unexplained epistaxis
Decreased or complete loss of sense of smell
Headache or facial pain in the forehead region
Periorbital swelling, proptosis, or diplopia
In advanced cases, personality changes or seizures

Diagnosis Methods

Contrast-enhanced MRI of the nasal sinuses and brain is the primary diagnostic modality; computed tomography is added to demonstrate bony changes. Endoscopic visualization through the nose allows direct tumor visualization and tissue sampling. Definitive diagnosis is established through pathological examination and special staining; additional imaging may be performed to evaluate dissemination.

Treatment Methods

Treatment is primarily based on surgical resection of the tumor. Currently, endoscopic transnasal resection is frequently preferred in suitable patients, avoiding external incisions; more advanced cases may require open surgery. Most patients receive radiation therapy following surgery; chemotherapy may be added in advanced or high-grade tumors.

Endoscopic transnasal tumor resection (in suitable patients)
Open surgery in advanced cases (skull base resection)
Postoperative radiation therapy (proton therapy when indicated)
Chemotherapy in advanced or high-grade tumors
