摘要
目的:探讨颅底咽旁间隙肿瘤的CT及MRI影像诊断分析。材料与方法:采用回顾性分析法,选取2013年2月至2014年8月在我院接受治疗的40例颅底咽旁间隙肿瘤患者的临床资料,观察患者CT及MRI影像表现。结果:经过影像学诊断分析后,发现患者CT扫描显示患者病灶区呈现等密度软组织肿块,增强扫描后有明显的强化;MRI影像扫描显示T1WI有等高或稍高周围肌肉信号,T2WI显示不均匀高信号,增强扫描后提示肿瘤高信号内有囊变坏死区,神经鞘瘤表现为圆形或椭圆形,边界光滑、包膜完整,鼻腔咽与口烟腔受压影响,并与肿瘤位置大小呈密切的关系。40例患者中有3例颈动脉体瘤、4例鼻咽癌颅底咽旁间隙转移、23例神经鞘瘤及10例涎腺混合瘤。结论:颅底咽旁间隙肿瘤的CT及MRI影像诊断能提高临床诊断率,提高患者治疗效果和预后。
Purpose： To investigate the diagnosis and analysis of CT and MRI imaging of the tumors in the lateral space of the skull base. Materials and Methods： the clinical data of 40 patients with tumor of the skull base adjacent to the skull base in our hospital from February 2013 to August 2014 were selected, and the imaging features of CT and MRI were observed. Results： after analysis of imaging, CT scanning in patients with that in patients with lesions showed soft tissue density mass and obvious enhancement on contrast enhanced CT scans, MRI scan showed T1WI with high or slightly high around the muscle signal, T2WI showed uneven high signal and enhancement scan prompted tumors with high signal with cystic and nec- rotic areas, schwannoma showed round or oval, smooth boundary, capsule, nasal pharynx and smoke chamber pressure influence, and and location of the tumor size was closely related. 40 cases of patients with 3 cases of carotid body tumor, 4 cases of NPC with skull base parapharyngeal gaps shift, 23 cases of schwannoma and 10 cases of mixed tumor of salivary gland. Conclusion ： the diagnosis of CT and MRI imaging of the tumors in the skull base of the skull base can improve the clinical diagnosis rate, improve the therapeutic effect and prognosis of patients.
