Abstract

Thymomas arising outside the anterior mediastinum are very rare. Their occurrence is likely to be related to ectopic thymus tissue. We report a case of thymoma in the middle mediastinum, right paratracheal region. There have been few reports of middle mediastinal thymoma. In the present case, (11)C-acetate positron emission tomography (PET) was useful for a preoperative suggestive diagnosis. Recently, (11)C-acetate has been reported to be a more sensitive PET tracer than (18)F-fluorodeoxyglucose and may be a promising tracer for complementing the deficiency of (18)F-fluorodeoxyglucose in PET imaging.

摘要

发生在前纵隔以外的胸腺瘤非常罕见。它们的出现可能与异位胸腺组织有关。我们报告一例位于中纵隔右气管旁区域的胸腺瘤。关于中纵隔胸腺瘤的报道很少。在本病例中，碳-11（¹¹C）-乙酸盐正电子发射断层扫描（PET）对术前提示性诊断很有用。最近，有报道称¹¹C-乙酸盐是一种比¹⁸F-氟脱氧葡萄糖更敏感的PET示踪剂，可能是一种有前景的示踪剂，可补充¹⁸F-氟脱氧葡萄糖在PET成像中的不足。
