Retroperitoneal Nonfunctioning Paraganglioma-Case Report

後腹腔無功能性副神經節瘤一病例報告

摘要


神經鞘瘤是一種較少見且原發於神經鞘的腫瘤,其中良性較多。惡性較少,通常是發生在頭、頸部及四肢的周邊神經,很少有生長在後腹腔。後腹腔惡性神經纖維鞘瘤在術前正確診斷較困難,藉著腹部電腦斷層檢查及超音波檢查,可以瞭解腫瘤的相關位置。以利手術的進行。至今根除性手術切除腫瘤仍是最好的治療方式。三軍總醫院近十年治療二例發生於後腹腔的惡性神經纖維鞘瘤。本文報告其病程。診斷及治療並參考國外文獻討論之。

We report an unusal case of a retroperitoneal paraganglioma. As there was no symptom of a catecholamine-secreting neoplasm, the tumor was believed to be nonfunctional. No specific blood test is able to detect the presence of the tumor. Therefore, the preoperative diagnosis is difficult. However, the newer diagnostic aids, such as ultrasound and computerized tomography scanning, are necessary preoperatively to evaluate tumor's location and possible coexisting tumors. This report discusses a case of retroperitoneal nonfunctioning paraganglioma treated in the Tri-Service General Hospital, their clinical course, diagnostic procedures and mode of treatment.
