Dural tear and pseudomeningocele are reported to occur with thoracic and lumbar burst fractures. Conventional myelography, computed tomography with intrathecal metrizamide, dynamic computed tomographic myelography, magnetic resonance imaging and magnetic resonance myelography have all been used to detect consequential dural injury and cerebrospinal fluid leakage. Early diagnosis helps prevent neural entrapment, meningitis and cerebrospinal fluid leaks. We report a case of dural tear and lumbar pseudomeningocele formation secondary to multiple lumbar spine burst fractures diagnosed by multidetector computed tomography and magnetic resonance imaging.

因腰椎爆裂骨折引致的硬腦膜撕裂及假性腦膜膨出：多排螺旋CT及磁共振診斷

JC Kandathil、M George

有報導指胸和腰椎爆裂骨折會引致硬腦膜撕裂及假性腦膜膨出。傳統的脊髓造影、CT鞘內造影、動 態CT脊髓造影、MRI及MRI脊髓造影都被用作診斷其誘發的硬膜損傷及腦脊液漏。及早診斷可預防 神經卡壓、腦膜炎及腦脊液漏。本文報告一宗用多排螺旋CT及MRI診斷涉及多個腰椎爆裂骨折併發 硬腦膜撕裂及假性腦膜膨出的病例。
