Objective: To assess the magnetic resonance imaging(MRI)characterisitics of spinal intramedullary ependymomas. Methods: MRI was done in 60 patients with spinal intramedullary ependymomas. All were operated on and histological diagnosis together with gross morphological descriptions were available. MR images of the tumors and associated cysts were compared with surgical findings in all subjects studied.

Objective: To assess the magnetic resonance imaging(MRI)characterisitics of spinal intramedullary ependymomas. Methods: MRI was done in 60 patients with spinal intramedullary ependymomas. All were operated on and histological diagnosis together with gross morphological descriptions were available. MR images of the tumors and associated cysts were compared with surgical findings in all subjects studied. Results: 39 tumors were cervical, 11 were thoracic, and 10 were conus medullaris and filum ferminale. The lesions measured 1 to 10 vertebral segments in length along the neuraxis, with a mean length of 3.7 segments. All tumors had slightly hyperintense signal on T2WI. All patients received contrast material and tumors were enhanced by contrast material. Rostral and caudal cysts were seen in 54 tumors., all cysts were hypointense relative to signal intensity of spinal cord on T1weighted SE images and hyperintense to the signal intensity of spinal cord on T2weighted SE images. The rostral cysts involving one to five segments and caudal cysts involving two to ten segments in length. Conclusion: Ependymomas occur seldom in the conus medullaris and filum terminale but in the upper cord. Of the cervical and thoracic lesions, most of them were typically cellular and epithelial ependymomas. Papillary ependymomas occur exclusively in the conus medullaris and filum terminale. Rostral and caudal cysts are frequently associated with intramedullary ependymomas. The cervical cysts extended above the level of the pyramidal decussation, elevating the floor of the lowermost part of the fouth ventricle is a pathognomonic sign and serves as a distinguishing feature of spinal cord ependymomas. The pathogenesis of syrinx formation was also analyzed.

目的:探讨脊髓室管膜瘤的MRI特征性表现。方法:对60例经手术及病理证实的脊髓室管膜瘤的MRI表现进行分析。特别对与肿瘤相关的头及尾端的脊髓囊腔的特征进行了分析。结果:肿瘤实体主要位于颈髓(包括部分累及延髓及胸髓)39例;主要位于胸髓(包括部分累及颈髓及腰髓)11例。位于圆锥马尾10例。肿瘤实体沿脊髓纵轴累及由1~10个椎体不等:平均3.7个椎体。在T2WI,60例均为略高信号。注射Gd-DTPA后,47例肿瘤轻度强化;13例明显强化。60例中,54例合并脊髓囊腔。囊腔位于肿瘤两端,居中。近端囊腔较远端囊腔短。近端囊腔累及1~5个椎体,远端囊腔累及2~10个椎体。结论:颈胸髓脊髓室管膜瘤的发生率明显高于下部脊髓,圆锥和终丝。脊髓下段肿瘤以乳头型为主,而脊髓上段肿瘤以上皮型及细胞型为主。与肿瘤相关的脊髓囊腔,特别是上颈段囊腔延伸至延髓(锥体交叉以上),造成第四脑室底部上抬的特有征像。为脊髓室管膜瘤颇具特征性表现。对脊髓囊腔的发生机制进行了分析。

Objective To evaluate the diagnosis and the operative procedure of the spinal intramedullary ependymoma. Methods 16 cases of spinal ependymoma confirmed operatively and pathologically were reviewed. 9 male and 7 female with average age of 33.5 years were included in this study. The primary symptoms were mainly numbness, weakness and paresthesia of extremities with the characteristics of progressing from upwards to downwards. 13 cases were MR-scanned, showing intramedullary space occupying...

Objective To evaluate the diagnosis and the operative procedure of the spinal intramedullary ependymoma. Methods 16 cases of spinal ependymoma confirmed operatively and pathologically were reviewed. 9 male and 7 female with average age of 33.5 years were included in this study. The primary symptoms were mainly numbness, weakness and paresthesia of extremities with the characteristics of progressing from upwards to downwards. 13 cases were MR-scanned, showing intramedullary space occupying lesions. Its complete surgical removal was achieved in 11 patients, partial removal in 3, decompression and biopsy in 2. Results Twelve patients were followed up from 8 to 68 months. Symptoms in 7 patients were obviously improved. Spinal function scores were increased by 11 to 20 in 4 cases, less than 10 in 3. Symptoms were stable in 3 cases, worsened again after postoperative relief in 2. Conclusion The specific clinical and radiological findings are the principal evidence for the diagnosis of the intramedullary ependymoma. Since the growth of the tumor is through intramedullary extension, it usually has a clear boundary in the spinal cord. The lesion could be completely removed with experienced surgical technique. When the diagnosis is established, early surgery is recommended. The key point of successful removal is to explore a clear demarkation between the tumor and the spinal cord.

目的探讨脊髓髓内室管膜瘤的诊断、手术要点及注意事项。方法回顾分析经手术及病理证实的16例髓内室管膜瘤临床资料。男9例,女7例;年龄21~60岁,平均33.5岁。首发症状主要为受累肢体麻木无力和(或)感觉异常,随病程由上向下发展为其特征。13例行MR检查,示髓内占位性病变。完全切除11例,大部切除3例,减压活检2例。结果12例得以随诊,时间为8个月~5年8个月,症状明显改善7例,其中脊髓功能评分提高11~20分4例,10分以下3例;症状稳定3例;术后症状缓解再加重2例。结论特有临床表现及影像学所见为诊断主要依据,因其在髓内膨胀生长,多与脊髓界限清楚,掌握手术要点即可完全切除,诊断一旦确立,根据MRI所见,应尽早手术。术中探查其与脊髓界限是否清楚为手术关键。

Objective To evaluate the efficacy of embolization for spinal intramedullary arteriovenous malformations.Methods 25 patients with spinal intramedullary arteriovenous malformations (AVMs) were reviewed. Embolic therapy was conducted in 4 patients by introducing the tip of a catheter into the segmental arteries and injecting lyophilized dura or polyvinyl alcohol(PVA). Microcatheter were navigated into the feeding arteries and injected PVA in 9 patients, and NBCA in 7 patients. Embosphere was used after embolizing an aneurysm in the feeding artery with NBCA in one pateint. Results Spinal angiography immediately after embolization disclosed that the lesion were obliterated almost entirely in 12 cases and partially in others. The anterior or posterior spinal artery was preserved in all patients recently. The clinical follow-up period after embolization ranged from 6 to 60 months. 16 patients improved but four patients did not show any improvement.Conclusions Embolization appears to be the treatment of first choice in the management of juvenile or partial glomus AVMs which are not amenable to surgery.

目的 探讨脊髓髓内动静脉畸形的栓塞方法。方法  2 5例脊髓髓内血管畸形患者 ,均行血管内栓塞治疗 ,早期 4例在肋间动脉或腰动脉直接注射硬脑膜颗粒或PVA等 ,近期 9例将微导管插至供血动脉远端以PVA栓塞 ,1例先以NBCA栓塞供血动脉上的动脉瘤 ,再以Embosphere栓塞AVM。 7例以NBCA栓塞。 5例直接手术切除病灶 ,2例栓塞联合手术治疗。结果  2 0例栓塞后造影证实 12例几乎完全栓塞 ,8例为大部分栓塞 ,经半年~ 2年随访 ,16例临床症状均有不同程度改善 ,4例临床症状无明显变化 ,均未出现出血症状。结论 对于髓内幼稚型和不能手术的团块型AVM ,血管内栓塞治疗为首选治疗。
