目的:探讨咽旁间隙内腮腺基底细胞腺瘤(BCA)的CT特征及其与咽旁间隙的神经鞘瘤的鉴别要点。方法:报道并分析了咽旁间隙内基底细胞腺瘤1例的少见CT表现。复习了自2010年以来国内关于CT诊断腮腺基底细胞腺瘤的所有文献,其中有详尽数据和完整描述的,且每篇报道在10例以上的文献仅4篇,共计77例,83个病灶。本文对这些病灶的个数、大小、所处腮腺的部位、囊变及钙化进行了小计。结果:单发者占94.8%,位于腮腺浅叶者占86.7%,小于3 cm者占92.8%,囊变者占60.2.%,钙化者占2.4%;咽旁间隙内腮腺基底细胞腺瘤位于二腹肌后腹的浅面,咽旁间隙脂肪内移。结论:咽旁间隙腮腺基底细胞腺瘤的CT表现具有一定的特征性,二腹肌后腹是鉴别咽旁间隙内基底细胞腺瘤和神经鞘瘤的分界线。
Objective: To investigate CT features of parathyroid basal cell adenoma (BCA) in the parapharyngeal space and its main points of differentiation from schwannoma of parapharyngeal space. Methods: A rare CT appearance of basal cell adenoma in the parapharyngeal space was reported and analyzed. Review of all the literature on CT diagnosis of parotid basal cell adenoma in China since 2010, there are detailed data and complete description, and each article in more than 10 cases reported only 4 articles, a total of 77 cases, 83 lesions. In this paper, the number of these lesions, size, location of the parotid gland, cystic and calcification subtotal. Results: 94.8% of the patients had solitary parotidectomy, 86.7% of the parotid was located in the parotid gland, 92.8% of the patients were less than 3 cm, 60.2% of the cysts were cystic and 2.4% of the patients were calcified. The parotid basement adenoma was located in the parapharyngeal space Abdominal abdominal abdominal shallow, parapharyngeal fat transfer within the gap. Conclusion: CT findings of parapharyngeal parotid basement adenoma have certain characteristics. The dorsalis of abdominal muscles is the dividing line between basal cell adenoma and schwannoma in parapharyngeal space.
