A rare incidence of retroperitoneal Cystic Lymphangioma in a 45-year-old female - A Case Report.

INTRODUCTION AND

IMPORTANCE

Cystic lymphangioma is an extremely rare benign vascular neoplasm of mesodermal origin, arising from lymphatic vessels and occurring principally in male children. The retroperitoneum is the rarest site, accounting for <1 % of all types of lymphangioma. The incidence of cystic lymphangioma is unknown due to the scarcity of published data.

CASE PRESENTATION: A 45-year-old female presented to our hospital complaining of vague abdominal pain and intermittent episodes of vomiting over four months. Preoperative imaging via ultrasound and Computed Tomography revealed a well-demarcated retroperitoneal cystic mass between the right kidney and the liver.

CLINICAL DISCUSSION: The mass was excised laparoscopically. Histopathological examination confirmed a cystic hygroma (a subtype of cystic lymphangioma).

CONCLUSION

Cystic lymphangioma is rare, often misdiagnosed and may present with vague symptoms. Complete resection may be feasible and can be curative.
