摘要/Abstract

摘要： 　　目的　探讨用磁共振 (MR)轧喷酸葡胺 (Gd DTPA)增强扫描对脑囊尾蚴病退变期定性和定位诊断的价值。　方法　 6 9例行MR增强扫描诊断为退变期脑囊尾蚴病患者 ,并经手术或血清特异性囊尾蚴抗体检测证实 ,对比分析其MR平扫与增强扫描。　结果　 6 9例患者经MR平扫呈单发或多发 ,片状长T1、长T2异常信号 ,经MR增强扫描后T1加权像呈在大片低信号中见小结节状或环状强化 ,强化后的病灶直径最大不超过 2 2mm ,平均直径 8.1mm。其中 4例患者MR平扫呈单发病灶而经MR增强扫描后呈多发强化。　结论　退变期脑囊尾蚴病MR增强扫描有较典型的表现 ,且可明确病灶的数目、部位及受累范围 ,能提高鉴别诊断的准确性。

Abstract: 　Objective To detect the value of qualitative and orientating diagnosis in the degeneration stage of cerebral cysticercosis with Gd-DTPA enhanced MR. Methods Sixty-nine cases of cerebral cysticercosis were diagnosed by enhanced MR as degeneration stage, and confirmed by immunological examination and/or by surgery. MR plain scanning was conducted for the same cases. Results The plain scanning showed single or multiple lesions with long T1 and long T2 signals, and the enhanced scanning showed nodular or annular lesions. The diameter of the lesion after enhanced scan was not more than 22mm with an average value of 8.1mm. Some cases showed single lesion on plain scanning but showed multiple lesions after enhanced scan. Conclusion The enhanced MR shows more typical features of the degeneration stage cerebral cysticercosis. It can define the number, position and range of the lesions, and can improve the accuracy of differential diagnosis, and therefore be of importance in formulating treatment scheme and prognosis.
