Evaluation of narrow band imaging for diagnosis of unilateral nasal lesions

Evaluation of narrow-band imaging in the diagnosis of sinonasal inverted papilloma

KEY POINTS

Narrow-band imaging (NBI) can be used to differentiate benign sinonasal lesions NBI can be used in the preoperative identification of sinonasal inverted papilloma Future studies can focus on NBI for recurrent inverted papilloma and surgical margin guidance.

Narrow-band imaging for detecting nasal lymphoma

INTRODUCTION

Narrow-band imaging (NBI) is an advanced endoscopic technique that enhances the mucosal neovascularization. The utilization of narrow-band imaging on the detection of nasal lymphomas is not well-established.

AIM

To present a clinical case whose nasal lymphoma was detected with the aid of NBI.

CASE REPORT

A 91-year-old male presented to the ear, nose, and throat clinic with right persisting nasal obstruction for 4 months. NBI revealed a well demarcated lesion with an elongated vessel on the surface of the right inferior nasal turbinate. Histopathologic analysis of tissue specimen proved to be extranodal NK/T-cell lymphoma, nasal type.

CONCLUSIONS

NBI is useful for the detection of nasal lymphomas. NBI may be a valuable screening tool for nasal lymphomas as it is non-invasive and affordable.
