An unusual case is reported of an intradural lumbar arachnoid diverticulum causing mild compression of the cauda equina and producing debilitating symptoms which were relieved by inadvertent drainage. A survey of the literature indicates that lumbar arachnoid diverticula are very rare. Only one other report of an intradural lesion of this type has been found. These lesions cause back pain or radicular pain and sensory disturbances when the patient is upright of bending forward. These symptoms are relieved by lying down. Percussion tenderness over the level of the diverticulum is a consistent finding. The key to the diagnosis is supine myelography.
本文报告了一例罕见的硬脊膜内腰椎蛛网膜憩室病例，该憩室导致马尾轻度受压并产生使人衰弱的症状，这些症状因意外引流而缓解。文献调查表明，腰椎蛛网膜憩室非常罕见。仅发现另一例此类硬脊膜内病变的报告。这些病变在患者直立或向前弯腰时会引起背痛、神经根性疼痛和感觉障碍。躺下后这些症状会缓解。憩室水平处的叩击压痛是一个一致的发现。诊断的关键是仰卧位脊髓造影。
