Enterogenous cysts are rare tumors found most commonly in the spine, but they have also been reported intracranially. Cases of enterogenous cysts located within the posterior fossa have traditionally been resected via difficult craniotomies that require prolonged retraction and risk injury to cranial nerves. We describe a method for resection of an enterogenous cyst located anterior to the brainstem via the endoscopic transsphenoidal approach.
A 37-year-old man was found to have a 2-cm mass anterior to the brainstem during routine screening after a trauma. The mass was located within the prepontine cistern, enhanced with gadolinium contrast, and showed no restrictive diffusion. This lesion was most consistent with an enterogenous cyst. A minimally invasive endoscopic endonasal transsphenoidal transclival approach was performed for gross total resection of the tumor.
We discuss the endoscopic transsphenoidal approach used for the resection of an enterogenous cyst in the posterior fossa anterior to the brainstem. The transsphenoidal approach provides direct access to lesions in this location using a minimally invasive technique while avoiding excessive brain retraction or injury to cranial nerves. In addition, we provide an updated review of the literature for enterogenous cysts located within the posterior fossa.
肠源性囊肿是一种罕见的肿瘤,最常见于脊柱,但也有颅内报道。传统上,位于颅后窝的肠源性囊肿通过需要长时间牵拉并可能损伤颅神经的困难开颅手术切除。我们描述了一种通过经蝶内镜入路从前颅底切除肠源性囊肿的方法。
一名 37 岁男性在创伤后常规筛查时发现脑干前有 2cm 大小的肿块。该肿块位于桥前池内,钆对比增强,无限制扩散。该病变最符合肠源性囊肿。为了实现肿瘤的大体全切除,采用了微创内镜经鼻蝶入路。
我们讨论了用于切除位于脑干前颅后窝肠源性囊肿的经蝶内镜入路。经蝶入路通过微创技术直接进入该部位的病变,同时避免过度牵拉脑组织或损伤颅神经。此外,我们还对位于颅后窝的肠源性囊肿的文献进行了更新回顾。
