Lymphangiomas are uncommon benign tumors that most commonly present early i
n life, and are even more exceptional in adults.
We present a rare case of a 14-week pregnant woman who had a large septated
cystic lesion adherent to the ileum. Despite analysis by ultrasound, the c
orrect diagnosis was established only via laparotomy and she had surgical r
esection of an abdominal lymphangioma.
