Abstract
Objective To investigate the clinical features and surgical treatment method of cauda equina schwannoma. Methods Clinical symptoms, imaging characteristics and functional outcomes after surgical treatment of 32 patients with cauda equina schwannoma from June 2007 to March 2009 were retrospectively reiewed. Results Most patients (30 cases) suffered lower extremity numbness/pain before operations and 18 of them suffered in both lower extremities. Physical examination showed bilateral nerve damage or unilateral multiple nerve damage in 25 cases. The initial symptom of 12 cases was simple lumbago. Ten cases were misdiagnosed as lumbar disc herniation. Six patients were scanned by computed tomography but none of them was diagnosed correctly. All the patients were definitely diagnosed by magnetic resonance imaging (MRI) , the typical appearance of the schwannoma was a round or ovoid mass with isointense or slightly hyperintense on T1-weighted images, while on T2-weighted images with heterogeneous hyperintense in 25 cases, slightly hyperintense in 2, and homogeneous hyperintense in 5. Gadolinium-enhanced MRI was performed in 13 patients, of whom 10 cases showed heterogeneous or annular enhancing. In all patients, the tumor was resected completely, the functional outcomes were satisfactory except one with a giant tumor, in whom the neurological symptom was aggravated, and no recurrence was found during a short-term follow-up.Conclusions The characteristic features of cauda equina schwannoma were lower extremities numbness/pain and bi- or unilateral polyradiculopathy in physical examination. MRI is helpful for early diagnosis and recommended as the first choice. Functional outcomes are satisfactory in patients with tumor completely resected.关键词
