In many cases splenic tumor qualitative diagnosis before surgery is difficult, as diagnostic and treatment often require spleen removal surgery. We experienced a case of an inflammatory pseudotumor of the spleen witch was incidentally found and diagnosed by laparoscopic splenectomy. A 59-year-old woman admitted for medical examination of a hypoechoic tumor in the spleen found by abdominal echography had no complaints. Abdominal enhanced CT showed heterogeneous enhanced tumor of spleen in early phase and delay phase. We conducted laparoscopic splenectomy under a diagnosis of primaly splenic tumor, because a possibility of malignancy could not be ruled out. The postoperative histological findings showed an inflammatory pseudotumor of the spleen. We often have difficulty in making diagnosis of inflammatory pseudotumors of the spleen by imaging methods before operation. Inflammatory pseudotumor is basically benign and has good prognosis. So if it can be diagnosed preoperatively in future, its clinical course can be observed. However, recent report have described that inflammatory pseudotumors include true neoplasm. We have to consider to perform operation for diagnosis as well as therapy.
