Paragangliomas in the cauda equina region: clinicopathoradiologic findings in four cases.
Paragangliomas of the cauda equina are rare neuroendocrine tumors. Four cases of nonsecreting paraganglioma of the cauda equina, preoperatively misdiagnosed as neurinoma, are presented with an emphasis on the correlation between magnetic resonance imaging findings and pathological features. Although it is difficult to correctly diagnose paraganglioma preoperatively for intradural extramedullary tumors, especially in the cauda equina, paraganglioma should be included in differential diagnoses.
