A rare case of leiomyoma of the prestyloid parapharyngeal space is reported together with computed tomographic and magnetic resonance imaging findings. The tumor appeared as a well-circumscribed ovoid mass with some calcifications and lobulations. Because the attenuation, signal intensity, and shape of the mass were not specific and were similar to those of a pleomorhic adenoma, the most common tumor of the prestyloid parapharyngeal space, radiological differentiation of leiomyoma from pleomorphic adenoma of the prestyloid parapharyngeal space was difficult.
本文报告了1例茎突前咽旁间隙平滑肌瘤的罕见病例，并展示了其计算机断层扫描和磁共振成像结果。肿瘤表现为边界清晰的卵圆形肿块，伴有一些钙化和分叶。由于肿块的密度、信号强度和形态不具有特异性，与茎突前咽旁间隙最常见的肿瘤——多形性腺瘤相似，因此在影像学上很难将茎突前咽旁间隙平滑肌瘤与多形性腺瘤区分开来。
