磁共振(MRI)应用于临床以来,椎管内肿瘤的诊断率明显提高。我们对4例因不能行椎管造影或显影不确实者行MRI检查,确诊为椎管内肿瘤,均经手术证实,现报告如下。 例1:患者,男,33岁。患者走路不稳、四肢乏力5年,曾诊断为“遗传性共济障碍”。病程中时有反复,进展至四肢痉挛性瘫痪。双上肢肌力Ⅱ级,双下肢肌力Ⅰ级,腱反射亢进,踝阵挛,髌阵挛阳性。双侧可引 Magnetic resonance imaging (MRI) has been used clinically since the diagnosis of spinal tumors has been significantly improved. We were 4 cases because they can not line imaging or imaging is not accurate MRI examination of the line, diagnosed as spinal canal tumor, were confirmed by surgery, are as follows. Example 1: Patient, male, 33 years old. Patients walking unsteady, limb weakness for 5 years, had been diagnosed as “hereditary disability.” During the course of the disease repeatedly, progress to limb spastic paralysis. Upper limb muscle strength Ⅱ, lower limb muscle strength Ⅰ, tendon hyperreflexia, ankle clonus, positive patellar clonus. Bilateral can lead
