INTRODUCTION
Schwannomas are the second most common type of intra-dural lesions involving the thoracic spine. They are frequently seen as solid and heterogeneous lesions. Totally cystic thoracic schwannomas represent a rare pathological schwannoma variant, with only four cases reported in the English literature to our knowledge.
CASE PRESENTATION
We report an 80-year-old male who presented with upper back pain for 3 months. Magnetic resonance imaging (MRI) showed a cystic lesion at the level of T6-T7 with peripheral contrast enhancement. The lesion was removed in total surgically with complete resolution of the patient's symptoms.
DISCUSSION
The diagnosis of cystic schwannomas is often delayed due to the paucity of symptoms and the lack of meticulous investigation. The presence of rim enhancement on contrast-enhanced MRI may be the only clue for the diagnosis. It is important to consider cystic schwannomas in the differential diagnosis of cystic spinal lesions since the best surgical outcome is strongly related to earlier diagnosis and total resection of the lesion.
简介
神经鞘瘤是第二常见的累及胸段脊柱的硬脊膜内病变。它们通常表现为实性和异质性病变。完全囊性胸 schwannoma 是一种罕见的病理性 schwannoma 变体，据我们所知，仅在英文文献中报道了 4 例。
病例介绍
我们报告了一名 80 岁男性，因背痛 3 个月就诊。磁共振成像（MRI）显示 T6-T7 水平有一个囊性病变，周围有对比增强。该病变完全通过手术切除，患者症状完全缓解。
讨论
由于症状稀少且缺乏细致的检查，囊性 schwannoma 的诊断常常被延误。增强 MRI 上的边缘增强可能是诊断的唯一线索。在囊性脊柱病变的鉴别诊断中，考虑囊性 schwannoma 很重要，因为手术结果的好坏与早期诊断和病变的完全切除密切相关。
