Hydatid cyst is a disease caused by the larvae of Echinococcus spp. The larvae often reside in the liver, lungs, and brain. Occasionally, a primary isolated thoracic vertebral hydatid cyst is reported to cause severe complications. Various diseases may lead to the development of progressive compressive myelopathy. Herein, we report a rare case of a primary isolated thoracic vertebral hydatid cyst with compressive myelopathy.
A 57-year-old female had numbness and weakness in the lower limbs for a span of 3-months.
Thoracic magnetic resonance imaging (MRI) showed that an isolated mass was observed in the T5 vertebral body, which compressed the spinal cord. The diagnosis was confirmed after surgical excision, and Echinococcus granulosus was found to be the etiologic factor.
The patient underwent laminectomy with no complications.
After surgical decompression, the patient made slow and measurable progress. While relatively rare in the non-pastoral area, the primary isolated thoracic vertebral column hydatid cyst may be considered as a possible etiology of atypical extradural spinal compression.
This case illustrates the complexity of spinal echinococcosis manifestations and the necessity of an interdisciplinary approach.
包虫囊肿是由细粒棘球绦虫幼虫引起的疾病。幼虫常寄生于肝、肺和脑。偶尔有报告称原发性孤立性胸椎间盘包虫囊肿可引起严重并发症。各种疾病可能导致进行性压迫性脊髓病的发展。本文报告一例罕见的原发性孤立性胸椎间盘包虫囊肿伴压迫性脊髓病。
一名 57 岁女性下肢麻木无力 3 个月。
胸椎 MRI 显示 T5 椎体可见孤立性肿块，压迫脊髓。手术切除后确诊，病因是细粒棘球绦虫。
行椎板切除术，无并发症。
手术后减压，患者病情逐渐改善。在非牧区，原发性孤立性胸椎间盘包虫囊肿虽较为少见，但可能是引起非典型硬脊膜外脊髓压迫的一个病因。
该病例说明了脊髓包虫病表现的复杂性，需要多学科方法进行治疗。
