摘要
目的 分析眶尖部海绵状血管瘤、海绵状淋巴管瘤及神经鞘瘤的MRI特点 ,为临床诊治提供根据。方法 对经MRI检查、手术及组织病理学证实的 16例眶尖部肿瘤进行分析。结果 3种眶尖部肿瘤的MRI的增强扫描完全强化时间不同。其中 5例海绵状血管瘤所用的时间平均为12min 31s ;6例海绵状淋巴管瘤所用的时间平均为 7min 7s ;5例神经鞘瘤所用的平均时间为 3min2 7s,差异有非常显著性 (P <0 .0 1) ,MRI增强扫描完全强化所用的时间与各肿瘤组织病理学特点有关。结论 MRI的增强扫描完全强化所用时间不同 。
Objective To analyze magnetic resonance imaging (MRI) features of confusable tumors including cavernous hemangioma, cavernous lymphangioma and neurilemmoma located at orbital apex, which could provide evidences for diagnosis and surgical treatment Methods MRI was performed on 16 cases with tumors of orbital apex confirmed by pathology, and their MRI findings were analyzed Results The time taken to attain complete enhancement after contrast on MRI was significantly different in the three types of tumor ( P <0 01) Their enhancement patterns were related to their pathologic findings Conclusions The different enhancement patterns of various tumors of orbital apex are characteristic for diagnosis and differential diagnosis
