 A 27-year-old woman was admitted to our hospital with the complaint of left abdominal pain and dysphagia. Abdominal CT revealed a 12×10 cm monolocular cystic lesion in the upper pole of the spleen, and serum CA 19-9 value showed high level of 766 U/ml. No apparent findings of malignancy were identified by imaging, so the operation was performed with the diagnosis of a splenic cyst. At first, 3 ports were inserted into her abdomen and S.A.N.D. balloon catheter was used for suction of the intracystic fluid. The cystic fluid was brown, and CA 19-9 in the cystic fluid was as high as 328,000 U/ml. The proximal region transitional to the parencymal spleen was resected. A cyst wall consisted of fibrous connective tissue with calcification. Histopathology revealed it to be a pseudocyst. Laparoscopic dome resection for splenic cyst is a safe and useful procedure for the preservation of splenic function.
