This report documents the findings of two rare cases of mature cystic teratoma of the pancreas. Although they could not be diagnosed preoperatively, our retrospective report suggests that the combined diagnosis of ultrasonography (US), enhanced computed tomography (CT), and magnetic resonance cholangiopancreatography (MRCP) might allow differentiation from other cystic lesions such as mucinous cystic tumors (MCTs) and intraductal papillary-mucinous tumors (IPMTs). Since the cystic teratomas were both filled with keratinous and sebaceous material, they were echogenic, appearing as solid masses on US. Enhanced CT showed their cystic nature, with values slightly higher than water, and MRCP revealed defects of internal signals.
本报告记录了两例罕见的胰腺成熟性囊性畸胎瘤病例的研究结果。尽管术前未能确诊，但我们的回顾性报告表明，超声检查（US）、增强计算机断层扫描（CT）和磁共振胰胆管造影（MRCP）联合诊断可能有助于与其他囊性病变如黏液性囊性肿瘤（MCTs）和导管内乳头状黏液性肿瘤（IPMTs）相鉴别。由于囊性畸胎瘤均充满角质和皮脂物质，它们在超声检查时呈强回声，表现为实性肿块。增强CT显示其囊性特征，密度略高于水，MRCP显示内部信号缺损。
