Abstract

Intradural extramedullary tuberculoma without any bony involvement is exceptional. Nineteen cases were found in the literature. We report the case of 5-year-old boy who presented acute paraplegia 8 months after a tuberculous meningitis under antituberculous treatment. Dorsal gadolinium enhanced MRI revealed an intradural extramedullary bunch-shaped enhancing mass at T5-T6 level. The tuberculous nature was confirmed by histology after surgical removal of the lesion followed by a good recovery. To our knowledge, this is the first intradural extramedullary tuberculoma detected by MRI. We underline the role of MRI in the diagnosis of this particular localisation of tuberculosis.

摘要

无任何骨质受累的硬脊膜内髓外结核瘤极为罕见。文献中仅发现19例。我们报告一例5岁男孩，在抗结核治疗的结核性脑膜炎8个月后出现急性截瘫。胸椎钆增强磁共振成像显示在T5 - T6水平有一个硬脊膜内髓外束状强化肿块。手术切除病变后经组织学检查证实为结核性质，随后恢复良好。据我们所知，这是首例经磁共振成像检测到的硬脊膜内髓外结核瘤。我们强调了磁共振成像在诊断这种特殊部位结核中的作用。
