Sinonasal schwannoma of the middle turbinate.

Paranasal schwannomas are uncommon lesions, representing less than 4% of all head and neck schwannomas. They give rise to nonspecific symptoms such as nasal obstruction, epistaxis, and anosmia. Imaging features are generally nonspecific. Here, we present the radiologic features of a benign schwannoma of the middle turbinate with dural invasion in a 71-year-old woman.
