鼻石CT诊断

CT Diagnosis of Rhinolith

目的探讨鼻石的CT诊断价值。方法回顾性的分析8例鼻石患者的临床资料。结果患者主要的症状为鼻塞和流脓涕;HRCT扫描见6个病灶中心见低密度的核心,周围为均匀的高密度无机盐影,为本病较特征性影像学改变;HRCT同样可发现并发的鼻窦炎症和中隔偏曲或穿孔。结论HRCT有助于鼻石的诊断和鉴别诊断。

Objective To study the CT features of rhinolith and to evaluate the value of CT diagnostic. Method Eight cases with rhinolith are analyzed retrospectively. In addition the literatures about this disease are reviewed. Results The main clinical findings of patients with rhinolith included purulent discharge and nasal obstruction. On CT scans six lesions showed low density in central region as the nidus and high density in peripheral region due to the deposition of mineral salts. CT also demonstrated complications such as maxillary sinusitis, deviation or perforation of the nasal septum. Conclusion HRCT findings may aid the diagnosis and differential diagnosis of rhinoliths.
