Cystic hygroma of the parotid gland is an uncommon benign congenital neoplasm that presents as an asymptomatic soft fluctuant mass. Cervical ultrasonography, computerized tomography (CT) and magnetic resonance imaging (MRI) are used to assess the size and extent of the lesion and to assist in planning the surgical approach. Ultrasonography may demonstrate a multilocular cystic mass containing septa of variable thicknesses. Extension of the mass into deeper structures is more accurately assessed by CT or MRI. A CT scan may show thin-walled cystic masses filled with material of density close to that of water. The use of contrast medium can demonstrate the relationship of the lesion to the surrounding structures. Magnetic resonance imaging is superior to CT in defining the nature and extent of the lesion.
腮腺囊性水瘤是一种罕见的良性先天性肿瘤，表现为无症状的柔软波动性肿块。颈部超声、计算机断层扫描（CT）和磁共振成像（MRI）用于评估病变的大小和范围，并协助规划手术方法。超声可能显示一个多房性囊性肿块，含有厚度不一的分隔。CT或MRI能更准确地评估肿块向深部结构的延伸情况。CT扫描可能显示薄壁囊性肿块，内充满密度接近水的物质。使用造影剂可显示病变与周围结构的关系。在确定病变的性质和范围方面，磁共振成像优于CT。
