[Iconographic imaging (ultrasound/MRI) in prenatal evaluation of cervical cystic lymphatic malformations].
OBJECTIVE
Assess imaging (ultrasound±MRI) in the diagnosis of cervical cystic lymphangioma.


METHODS
Retrospective, descriptive study of the patients who underwent reference ultrasound screening for fetal anterior cervival masses in multidisciplinary prenatal diagnosis center of the Lille Regional University Hospital from 1997 to 2014.


RESULTS
Seventeen lymphangiomas were identified. Seventy-three percent of lymphangiomas (n=12) were diagnosed in the baseline ultrasound and 85% (n=11) in MRI. An extra-cervical extension was identified in 10 (62%) with ultrasound and 11 (85%) with MRI. Main sites of mass extension objectived by ultrasound and MRI were respectively the face (4,23%/6,46%), the base of tongue (3, 18%/2, 15%) and buccal floor (3, 18%/3, 15%). Pharyngeal disease (5,38%) and mandible (4,31%) were detected by MRI and not found on ultrasound. Associated malformations detected with ultrasound were 2 (12%) urogenital malformation, 1 (6%) heart defect and 1 (6%) facial anomalies. Lymphangiomas remained stable in volume in 12 (71%) cases and disappeared before birth in 2 (12%) cases.


CONCLUSIONS
MRI and ultrasound seem inseparable to assess and optimally manage fetal cervical masses. Detection of associated lesions seems to help in the final lymphangioma diagnosis. Most of the time, lymphangiomas seem to be stable lesion during pregnancy and a good prognosis in cases of uncomplicated cervical lymphatic mass and without pejorative extension.
