Mesenteric lymphangioma presenting as adnexal torsion: Case report and literature review

We report the case of a patient with a mesenteric chylous lymphangioma who presented with acute pelvic symptoms mimicking adnexal torsion. The cyst contents had no specific sonographic or CT characteristics, such as a fluid-fluid level, to aid the preoperative diagnosis; definitive diagnosis was made only upon histopathologic examination of the cyst, which was resected intact. © 2005 Wiley Periodicals, Inc.
