Recurrent giant cystic lymphangioma of peritoneum: a case report and literature review

Abstract

Cystic lymphangioma (CL) is a rare benign tumor of the lymphatic system, most commonly found in the neck, head, and armpits. The incidence of lymphangiomas in the abdominal cavity is less than 5%, and the incidence of retroperitoneal tumors is even lower. We report here a case of recurrent giant CL that recurred 20 years after the first complete surgical resection. Pelvic MRI at 6 months follow-up after the second complete surgical resection indicated a recurrence of the tumor. The main purpose of this article is to explore the treatment and follow-up strategies for recurrent lymphangioma.

Keywords: case report; cystic lymphangioma; recurrence; surgical resection; treatment.

Pelvic-enhanced MRI images of arterial phase (A), venous phase (B), delayed phase (C), and Pelvic MRI revealed huge lesions in the pelvis, which were cystic, uniform, and multiventricular, including multiple compartments.

A large tumor occupies the pelvic cavity. The surface of the tumor is multilocular cystic, and the cystic fluid is pale yellow.
