与副鼻窦沟通的眼眶病变的临床影像学分析

目的探讨与副鼻窦沟通的眼眶病变的临床影像学表现。方法回顾性分析我院诊断的副鼻窦病变40例（40眼）术前均行CT检查，6例行X线检查、7例行MRI检查，均经手术及病理证实。结果上颌窦源性10例，筛窦21例，额窦7例，蝶窦2例。40例中良性病变31例，恶性病变9例。眼眶CT扫描结果显示良性病变边界清楚光滑，密度均匀，呈膨胀性骨质吸收破坏。恶性病变CT表现为边界不清，形状不规则，可见侵蚀性骨质破坏。结论副鼻窦病变易侵及眼眶，影像学检查有助于早期定性定位诊断。X线对副鼻窦病变的诊断具有筛查作用，CT和MRI结合对副鼻窦恶性肿瘤的诊断与鉴别诊断具有重要意义。

The clinical imaging analysis of paranasal sinus communication eye lesions

Objective To investigate the imaging findings of paranasal sinus communication eye lesions.Methods Forty cases of the paranasal sinus lesions were retrospectively analyzed.CT were performed in all cases; X-ray was performed in 6 cases; MRI was performed in 7cases.All cases were confirmed by operation and pathologic examination.Results The lesions were showed to originated from maxillary sinus in 10 cases,from ethmoidal sinus in 21cases,from frontal sinus in 7cases,from sphenoidal sinus in 2cases.31 cases with benign lesions and 9 cases with malignant disease.Orbital CT scan showed benign lesions with smooth and clear borders,homogeneous density,and dilatability bone absorption destruction.Malignant lesions performed blurred boundary,irregular shape and erosive bony destruction.Conclusion Paranasal sinus lesions could easily invade orbital,and imaging is helpful for early qualitative positioning diagnosis.X-rays plays a role in screening of paranasal sinus lesions.CT and MRI has significance in diagnosis and differential diagnosis of malignant lesions of paranasal sinus.
