Introduction:
Inflammatory pseudotumor of spleen is an extremely rare benign condition of uncertain etiology that presents with nonspecific symptoms or as an incidental finding in patients studied by other processes. Since the first description in 1984 by Cotelingam and Jaffe, only 114 cases have been reported.
Presentation Of Case:
We present a case of a fifty-six years old woman with a splenic injury in ultrasound and computed tomography. The patient undergoes laparoscopic splenectomy and the histologic study of the specimen revealed findings consistent with inflammatory pseudotumor of spleen.
Discussion:
This rare entity whose pathogenesis is still unknown, can present with nonspecific symptoms. Radiologic studies may lead the diagnosis being useful CT and MRI. The definitive diagnosis is established with the histological findings, characterized by the presence of inflammatory cells with areas of necrosis and fibrosis. There are multiple differentials diagnoses: metastasis, lymphoma, splenic infarction, hemangiomas, vascular malformations, lymphangioma, plasmacytoma, reactive lymphoid hyperplasia, abscess and infectious granulomatous processes; therefore suspicion of malignant neoplasm must be considered, being indicated splenectomy to confirm the diagnosis.
Conclusion:
Inflammatory pseudotumor of spleen is a benign disease, in which diagnostic approach must bear in mind the possibility of a malignant lesion. For this reason, the surgical approach is appropriate to confirm the diagnosis and rule out malignancy with histology.
