[A case of splenic inflammatory pseudotumor].

ABSTRACT

A 51-year-old woman who had undergone gastrectomy for advanced gastric cancer was found to have a splenic tumor during the postoperative clinical observation. Abdominal computed tomography (CT) demonstrated solitary splenic tumor 15mm in diameter with delayed contrast enhancement. Abdominal ultrasonography (US) revealed low echoic mass with enhancement at vascular and perfusion image. We performed splenectomy to exclude the possibility of the metastatic tumor. The tumor was histopathologically diagnosed as inflammatory pseudotumor because of the presence of acidophilic fiber proliferation, hyalinized tissue and infiltration of lymphocytes and plasma cells.
