咽旁间隙解剖结构的复杂性决定了咽旁间隙肿瘤的复杂性,也自然成为影像学诊断的难点部位之一[1]。发生咽旁间隙肿瘤最常见是腮腺深叶多形性腺瘤,其次为神经鞘瘤[2]。从CT上详细了解肿瘤的部位、范围、大小、肿瘤边缘以及周围组织结构关系,对临床治疗方案有重要意义。本研究收集经临床病理证实9例咽旁间隙多形性腺瘤、6例神经鞘瘤,对其CT
The complexity of the anatomical structure of the parapharyngeal space determines the complexity of the parapharyngeal space tumor, and naturally becomes one of the difficult parts of imaging diagnosis [1]. The occurrence of parapharyngeal space tumors is most often a deep pleomorphic adenoma of the parotid gland, followed by schwannoma [2]. The detailed understanding of the location, extent, size, tumor margin, and surrounding tissue structure of the tumor from the CT is of great significance to the clinical treatment plan. This study collected 9 cases of pleomorphic adenomas of the parapharyngeal space and 6 cases of schwannoma confirmed by clinical pathology.
