title: Laparoscopic observation of retroperitoneal cystic lymphangioma.
abstract: A case of retroperitoneal cystic lymphangioma observed laparoscopically is reported. In a 60 year old asymptomatic male patient, an 8 cm multi-loculated cystic lesion was detected incidentally near the splenic hilum with ultrasonography. Endosonography, computed tomography and magnetic resonance imaging revealed the lesion with thin wall and clear fluid. Laparoscopy showed a thin-walled cyst with smooth surface, and straw-coloured clear fluid was observed through the wall. These findings suggested benign aetiology, and seemed to be characteristic of cystic lymphangioma. The tumour was resected, and microscopic examination showed proliferated lymph channels intespersed by lymph follicles. Diagnosis of cystic lymphangioma was established. Laparoscopy seems a useful pre-operative method.
