Light microscopic examination of surgical biopsy specimens revealed an encapsulated mass composed of packets of polygonal cells of various sizes separated by a delicate fibrovascular stroma. G\u00f6m\u00f6ri's reticulum stain revealed a characteristic endocrine or \"Zellballen\" pattern. Tumor cells contained diffuse positive reactivity to synaptophysin and neuron-specific enolase, reactions consistent with a neuroendocrine neoplasm. S-100 protein-positive cells reminiscent of sustentacular (support) cells occurred singly or in small clusters within tumor packets. At postmortem examination 3 months later, a 9- X 5- X 4-cm multinodular raised tan mass involving the caudal pelvis, sacrum, and tail-head regions was found. The base of this neoplastic mass originated within the cauda equina region and involved approximately five caudal nerve roots. Numerous 1-3-mm metastatic nodules were identified disseminated throughout the pulmonary parenchyma. The tumor was diagnosed as a malignant paraganglioma of the cauda equina region with pulmonary metastasis.<\/jats:p>","DOI":"10.1177\/030098589703400313","type":"journal-article","created":{"date-parts":[[2010,1,22]],"date-time":"2010-01-22T22:34:19Z","timestamp":1264199659000},"page":"243-246","source":"Crossref","is-referenced-by-count":21,"title":["Malignant Cauda Equina Paraganglioma in a Cat"],"prefix":"10.1177","volume":"34","author":[{"given":"W.
