Identification of a Solitary Posterior Cervical Cystic Hygroma: A Case Report

Abstract

Purpose: To report a case of a post-term neonate with an isolated cystic hygroma upon birth. Methods: This is a retrospective case report followed by clinical observation, genetic testing, and surgical intervention. Results: A post-term neonate was found with an isolated left parapharyngeal cystic hygroma with no incidence of concurrent genetic syndromes upon karyotyping and underwent surgical removal. Discussion: Cystic hygromas are very commonly associated with genetic syndromes or maternal risk factors. If none exist, specific subtypes of cystic hygromas can also be inherited in an autosomal recessive fashion, a possibility that may need to be explored comprehensively
