ABSTRACT

Neurilmomma is a benign tumor which originate from the neuroectodermal Schwann cell of cranial, intraspinal, peripheral and autonomic nerve sheath. Although these tumors have been reported to occur throughout the body, the highest incidence, accounting for 25% to 45% of all cases, has been reported in the head and neck area. Except the acoustic neurilemmoma which is the most common in the otolaryngologic fields, neurilemmoma originating from the nasal cavity and paranasal sinus is very rare (about 4%). Recently, the authors have experienced a case of neurilemmoma of nasal cavity and thus presents the clinical and radiolographic findings along with a review of the literature.
