Title: A fetal MRI study on prenatal diagnosis of congenital cystic masses in maxillofacial and neck region
Abstract: Objective:To analyze the MRI features of congenital cystic masses in maxillofacial and neck region in fetuses,in order to improve prenatal imaging diagnostic level.Methods:MR images of 16 cases with congenital cystic masses in maxillofacial and neck region in fetuses were analyzed retrospectively,and were correlated with pathology or autopsy postnatally.Results:12cases of lymphangioma predominantly presented as multilocular masses,centered in the posterior space of the neck,invasive,and could across the midline.Bleeding signals and fluid-fluid levels could be seen when there was intracystic hemorrhage.3cases of branchial cleft cysts presented as unilocular masses,located in the neck anterior to sternocleidomastoid,and could had low or slightly low signals on T1 WI.One case of cranial meningocele from sella area protruded to the oral cavity had equal signals with the cerebrospinal fluid.Conclusion:Prenatal MRI could display outline,locations,shapes and signal features of masses,which is helpful for the differentiation of different congenital cystic masses in maxillofacial and neck region in fetuses.Moreover,MRI can reveal whether there is compression on the airway,which can provide more information for ex-utero intrapartum treatment.
