Figure 1 (A-D): Left sinonasal schwannoma. Axial T2 fat-suppressed (A) and axial post-contrast T1-weighted (B) images show a well-defined heterointense mass in the left nasal cavity and ethmoidal air cells which show inhomogeneous enhancement. Coronal T2 (C) and T2 fat-suppressed (D) images show the lesion is involving the left middle and inferior turbinates. This schwannoma is likely arising from the maxillary division of the trigeminal nerve. Preoperative biopsy revealed benign nerve sheath tumour and the postoperative histopathology confirmed schwannoma
