Inflammatory pseudotumor of the spleen in a patient with human immunodeficiency virus infection: a case report and review of the literature.

Inflammatory pseudotumor of the spleen (IPS) is a rarely described benign tumoral lesion of unknown etiology and pathogenesis. Diagnosis is complex as clinical manifestations and imaging features are indistinguishable from lymphoproliferative disorders and other malignancies of the spleen. Human immunodeficiency virus (HIV) infection is often combined with several malignancies including non-Hodgkin's lymphoma and Kaposi's sarcoma. However, no HIV infection-associated IPS has been reported so far. We report and discuss a case of IPS in an HIV-infected woman who presented with abdominal pain and multiple lesions in the spleen.
