Gallbladder lymphangioma: a case report and review of the literature.

Lymphangiomas are benign neoplasms usually occurring in childhood and located in the head and neck. Intraabdominal lymphangiomas account for less than 5% of cases. The involvement of the gallbladder is rare. We report a case of a 29-year-old woman who presented with right upper quadrant pain that had persisted for 6 months. Imaging with ultrasound and magnetic resonance imaging (MRI) revealed a multiseptated lesion surrounding the gallbladder. The patient underwent an exploratory laporatomy, and the mass was resected en bloc with the gallbladder. Histological evaluation of the cystic mass revealed findings consistent with lymphangioma. The prognosis is generally good after complete surgical excision, as was the case for our patient.
