影像学检查在蝶窦占位性病变诊断中的应用

Application of imaging modalities in diagnosis of space-occupying lesions of sphenoid sinus

蝶窦占位性病变是一类症状隐匿、临床相对罕见的疾病。复习相关文献 ,对各种蝶窦占位性病变的影像学特征及相关解剖、临床症状、体征进行综述 ,探讨影像学检查在蝶窦占位性病变诊断中的应用。资料表明 ,影像学检查特别是CT、MRI对蝶窦占位性病变的鉴别诊断与确诊、治疗与预后判断均具有重要参考价值。CT在显示骨性病变方面具有一定优势 ,MRI则更适于软组织显像 。

The space occupying lesion of sphenoid sinus is a relatively uncommon clinical entity with nonspecific clinical symptoms.A review of the literature was made in the present study to detail the imaging features and relative underlying symptoms,physical signs of the disease in order to evaluate the role of imaging modalities in diagnosis of the space occupying lesion of sphenoid sinus.Imaging modalities especially CT and MRI,were very useful in diagnosis and differential diagnosis which can provide evidence for treatment of space occupying lesion of sphenoid sinus and predicting prognosis.CT was superior to MRI in diagnosis of bony changes,but MRI was optimal in detecting soft tissues.Both CT and MRI could act as the routine method of choice.
