| Discussion | 1. Introduction Although schwannomas are common in head and neck, only 4% of schwannomas occur in sinonasal cavity. Clinically schwannoma are commonly misdiagnosed with other sinonasal tumors as they lack any specific clinical signs or symptoms. Patients with sinonasal schwannoma can present with varieties of nonspecific clinical symptoms depending on location and size of tumor. Late presentation is common especially if tumor arises from sinus cavity. 2. Radiologic findings Published description of the radiologic appearance of these benign tumors indicate that they present as a well demarcated solitary soft tissue mass, most commonly in the nasal cavity or ethmoid sinus. Over time, constant pressure by the mass on the surrounding structures may lead to bone remodelling and erosion as seen in this case. |
