摘要
目的提高脉络丛乳头状瘤的CT和MRI诊断水平。方法对8例脉络丛乳头状瘤患者的CT和MRI资料进行回顾性分析。结果8例患者中,4例位于第4脑室,2例位于侧脑室,1例位于第3脑室,1例位于桥小脑角区。CT表现为2例呈稍高密度肿块影,5例呈混合密度肿块影,1例呈囊性低密度内伴稍高密度结节及钙化。MRI表现为2例在T1WI上呈稍低信号,在T2WI上呈偏高信号影;5例在T1WI上呈低信号为主的混杂信号,在T2WI上呈高信号为主的混杂信号;1例以囊性信号为主,伴有低信号钙化影。结论脉络丛乳头状瘤CT、MRI表现具有一定特征性,结合CT及MRI检查有助于该疾病的诊断。
Objective To improve the levels of CT and MRI diagnosing for cboroid plexus papilloma. Methods The CT and MRI features of 8 patients with cboroid plexus papilloma were retrospectively analyzed. Results In these 8 patients, there were 4 cases in the fouth ventricle, 2 cases in the lateral ventricle, 1 case in the third ventricle and 1 case in the cerebellopontine angel. On CT findings, there were 2 cases appeared as slightly high density tumors, 5 cases appeared as mixed density tumors and 1 case appeared as low density cystic tumor accompany with slightly high density tubercle and calcification. On MRI findings, there were 2 cases appeared as slightly low signal intensity on T1WI and slightly high signal intensity on T2WI, 5 cases appeared as mixed signal intensity （low signal intensity were dominant） on T1WI and mixed signal intensity （high signal intensity were dominant） on T2WI,1 case appeared as cystic signal intensity accompany with low signal intensity of calcification. Conclusion The CT and MRI findings of cboroid plexus papilloma has invariably mark appearance. And it has some help in diagnosis of this tumor by using CT and MRI.
