 The case involves a 32-year-old woman who visited her local doctor with a chief complaint of abdominal discomfort and lack of appetite. A cystic lesion in her upper abdomen was noted on abdominal ultrasonography, following which she was referred to our hospital. Abdominal computed tomography (CT)confirmed a cystic lesion of approximately 10 cm diameter in the area surrounded by the hepatic left lobe, upper pancreas, and lesser curvature of the stomach. Imaging revealed no solid components that were indicative of a tumor within the uniform low-attenuation component of the cyst. Magnetic resonance imaging(MRI) revealed no communication between the cyst and the pancreatic duct. Further, polycystic components were confirmed via an endoscopic ultrasound. Based on these findings, she was diagnosed with cystic lymphangioma derived from the lesser omentum and underwent laparoscopic resection of the lesser omentum tumor. Histopathologic examination revealed cystic lymphangioma. Herein, we report the case with a review of relevant literature. Cystic lymphangiomas derived from the lesser omentum are rare, and in this case, laparoscopic resection was safely performed.
