title: Fetal axillary cystic hygroma: a case report and review.
abstract: Cystic hygroma (CH) is a lymphatic malformation occurring different parts of fetal body, typically in the region of the fetal neck and axillary, abdominal wall, mediastinal, inguinal and retroperitoneal areas. CH has been associated with fetal aneuploidy, hydrops fetalis, structural malformations and intrauterine fetal death.A 24-year-old gravida 1, para 1 was admitted to our hospital at 28 weeks of gestation. Ultrasonographic examination determined 28 weeks of gestation, singleton, alive fetus who had a mass derived from the right axillary region which was extending to the anterior and posterior thoracic wall with fluid-filled cavities about 12 cm in size. There was no evidence of intrathorasic or intraabdominal extension of mass. Cordocentesis was performed and karyotype examination was normal 46 XY. The fetal demise was found after the first visit. The patient was delivered vaginally after labor induction with oxytocin infusion. The fetal autopsy confirmed the diagnosis of CH.The fetal CH carries high risk of aneuploidy and fetal malformations. Patients that have been diagnosed with CH in antenatal follow-ups should be assessed in terms of other anomalies. Fetal karyotyping should be done and the patient should be monitored for fetal hydrops. The birth should be planned in a multidisciplinary hospital and as neonatal resuscitation could be needed, pediatricians should be consulted.
