Lymphangiomas are rare low-flow lymphatic vessel malformations mostly diagnosed in childhood. Among the abdominal lymphangiomas, the gallbladder lymphangioma is a rare presentation, and only a few cases have been reported till date, of which majority were cystic lymphangiomas. The authors present a case of a 48-year-old female with abdominal pain and normal physical examination and laboratory findings. On the performed imaging, a multiloculated cystic lesion, located in the gallbladder fossa, was found. The patient underwent open cholecystectomy, and surprisingly, the cyst extended to the common bile duct, which was separated cautiously. The cyst was resected, and the histopathological findings confirmed cystic lymphangioma. The cystic lymphangioma of the gallbladder can be asymptomatic, although most of the literature has reported abdominal pain. The diagnosis of lymphangioma is complicated, especially when intra-cystic hemorrhage happens. Ultrasonography, computed tomography, and magnetic resonance imaging are usually performed. The surgical excision of the cyst and the gallbladder is the treatment of choice. Although bile duct involvement is extremely rare, it should be considered during the surgery.
