摘要

脊索畸形是一种小的胶状组织,被认为是异位脊索残余。该组织位于颅脊髓轴的中线,从鞍背延伸至骶尾骨区(1-4)。颅内EP通常在脑桥前池内发现,通过一个小蒂附着在斜坡背壁上(1,2,5)。该区域回声通常无症状,只有少数研究报道了肿瘤扩张和压迫周围结构以及瘤外出血引起的相关症状。据我们所知,Alkan等人只报道过一次坡后性EP合并瘤内出血。我们报告一例31岁女性斜坡后EP合并瘤内出血的病例,其诊断基于CT和MR成像。

A Unique Case Of Ecchordosis Physaliphora With Intratumoral Haemorrhage
Ecchordosis physaliphora is a small, gelatinous tissue that is considered an ectopic notochordal remnant. This tissue is located in the midline of the craniospinal axis, reaching from the dorsum sellae to the sacrococcygeal region (1-4). Intracranial EP is typically found intradurally in the pre-pontine cistern, where it is attached to the dorsal wall of clivus via a small pedicle (1, 2, 5). Ecchordosis in this region are usually asymptomatic, and only a few studies have reported associated symptoms due to tumour expansion and compression of surrounding structures and extratumoral haemorrhage. To our knowledge retroclival EP with intratumoral haemorrhage has been described only once by Alkan et al. We report a case of retroclival EP with intratumoral haemorrhage in a 31 yr old female in which the diagnosis was based on CT and MR imaging.
