Abstract

Objectives: The etiology of Inflammatory myofibroblastic tumor(IMT) is contentious. In this study, we used computed tomography (CT) to examine tonsillar IMT and further analyzed the etiology of this entity.

Methodology: We presented CT features of left tonsillar IMT and reviewed the English-language literature published between 1984 and 2011.

Results: To our knowledge, there are only six published cases of tonsillar IMT including the present case. Two patients were asymptomatic at initial presentation. Two patients were taking immunosuppressants, and one was pregnant and in an immunomodulated state. CT of our patient revealed a 2.6 × 1.8 cm irregular soft tissue mass between the left tonsil and the base of the tongue. It did not invade surrounding structures and was not enhanced on contrast-enhanced imaging.

Conclusions: Tonsillar IMT may be a benign tumor. We suggest that preoperative recognition of tonsillar IMT by CT may be important to avoid unnecessary expanded surgery.

扁桃体炎症性肌成纤维细胞瘤的病因分析和计算机断层成像:一个免疫能力强的病人的报告和简要回顾。

目的:炎性肌纤维母细胞瘤(IMT)的病因有争议。在本研究中，我们使用计算机断层扫描(CT)检查扁桃体IMT，并进一步分析该实体的病因。方法:我们介绍了左扁桃体IMT的CT特征，并回顾了1984年至2011年间发表的英文文献。结果:据我们所知，包括本病例在内，仅有6例扁桃体IMT被发表。2例患者在初次就诊时无症状。2例患者正在服用免疫抑制剂，1例孕妇处于免疫调节状态。CT显示左侧扁桃体与舌底之间有一个2.6 × 1.8 cm的不规则软组织肿块。它不侵犯周围结构，增强成像不增强。结论:扁桃体IMT可能是一种良性肿瘤。我们建议术前通过CT识别扁桃体IMT对于避免不必要的扩大手术可能是重要的。
