颅底软骨瘤的影像诊断
Imaging Diagnosis of Skull Base Chondromas
【摘要】 目的 探讨CT、MRI诊断颅底软骨瘤的价值。方法 分析 8例颅底软骨瘤的病因、病理、影像表现及鉴别诊断。女性 5例 ,男性 3例。年龄 2 5~ 48岁。 8例临床症状表现有颅神经损害。 3例CT、MR ,4例MRI,1例CT检查。结果 3例位于海绵窦 ,2例斜坡 ,2例颈静脉孔 ,1例前颅窝。 4例CT检查肿瘤中都表现有斑块样钙化。 4例CT增强检查肿瘤不均匀强化 ,边界清楚。结论 CT对于颅底软骨瘤的诊断具有极其重要价值。MR在显示肿瘤生长方式以及肿瘤与邻近结构的解剖关系上明显优于CT。
【Abstract】 Objective To evaluate the value of CT MRI in diagnosing skull base chondromas.Methods 8 cases of skull base chondromas were analyzed with etiology,pathology,imaging fetures and differential diagnosis.5 cases were female,3 cases were male,age ranged from 25 to 48 years.The clinical presentation of 8 cases of skull base chondromas had neurologic syndrome.And 3 cases were examined with CT,MR imaging ,4 cases with MR imaging,1 case with CT scanning.Results In this series of 8 chondromas,3 located in the cavernous sinus,2 in the clival region,2 in the region of jugular foramen,1 in the frontal cranial fossa.Intratumoral calcification was found in 4 cases with CT examination.Heterogeneous enhancement was found in 4 cases with CT examination.The margin of chondromas on CT was well defined.Conclusion CT have a very important diagnosis values for detecting tumors on chondromas.MRI is superior to CT for delineating the growth style of the tumor and its relationship to the surrounding anatomic structures.
