A pitfall in diagnosing fetal abdominal lymphangioma: A report of two cases.

Typical ultrasound findings of fetal abdominal lymphangioma include thick-walled, multiseptated anechoic masses. Although a majority of cases can be suspected promptly by ultrasound examination, the two cases presented herein did not meet the standard criteria and were misleading. Both cases involved unilocular cysts without clear septations, but in retrospect were atypical findings of fetal abdominal lymphangioma. A few reports of misleading cases have been described previously; however, the precise characteristics have not been reported in detail. Therefore, in this case report, we focused predominantly upon the difficulties encountered in the prenatal diagnosis of abdominal lymphangioma based on ultrasound morphology alone.
