Abstract
BACKGROUND AND OBJECTIVES: Paraganglioma rarely develops in the spine. With few cases reported, little knowledge about this disease was known. The objective of this study is to illustrate the clinical features, imaging manifestations, pathological appearances and long-term outcomes of the consecutive surgeries by literature review. METHODS: The clinical and follow-up data of 18 patients who were diagnosed of spinal paraganglioma and treated with surgeries in our hospitals from 2003 to 2014 were retrospectively analyzed. RESULT: A total of fourteen patients radiographed of intra-spinal tumor underwent extra-capsular tumor resection. Of five patients with obvious vertebral bone damage, four cases underwent piecemeal resection, and the left one with sacral tumor underwent en bloc tumor excision. Spinal reconstruction was performed in all cases. Follow-up lasted for 16-96 months (44.1 months on average). There was no local recurrence or distant metastasis in cases without obvious bone invasion. Of those five cases with vertebral bone damage, one case suffered and survived from the repeat relapse of T1 vertebral body tumor. Local recurrence was not observed in one case with T10 vertebral tumor after tumor resection, but the tumor metastasized to T2 attachment during the follow-up and was finally eradicated by re-operation. No tumor recurrence was observed in the left three cases. CONCLUSION: Paraganglioma, usually benign, rarely occurs. Surgical resection, especially complete surgical resection, is preferred to treat spinal paraganglioma. Chemotherapy, radiotherapy, use of octreotide and other somatostatin are selected as adjuvant therapies, but their effects remain unknown.
