Abstract
A case of inflammatory pseudotumor of the spleen is reported. During observation of the course of cerebral infarction at the Department of Medicine, Fukagawa Municipal General Hospital, a 69-year-old male patient was found to have high levels of serum and urine amylase. Abdominal examinations by ultrasonography, computed tomography, magnetic resonance imaging, scintigraphy and angiography showed a hypovascular spherical mass with a diameter of 39 mm at the hilus of the spleen. Under a preoperative diagnosis of benign tumor such as hemangioma or hamartoma and with some possibility of a malignant tumor, splenectomy was performed on March 25, 1994. Macroscopically, the tumor (3.8×3.5cm) was white and nodular, with surrounding capsule. The tumor was diagnosed histologically as a plasma cell granuloma type of inflammatory pseudotumor. The patient was discharged from the hospital in good condition on Arpil 20, 1994.
