Inflammatory pseudotumour of the spleen: a diagnostic dilemma.

Inflammatory Pseudotumour (IPT) of the spleen is an extremely rare benign lesion of the spleen. It presents as a well-circumscribed mass which is usually solitary and composed of foci of inflammatory cells, mainly plasma cells and lymphocytes in a fibroblastic stroma. We report the case of a 24 year old male who complained of pain in the abdomen, with one episode of vomiting. An ultrasound scan of the abdomen and a contrast enhanced abdominal CT scan showed the presence of a cystic lesion in the spleen. Following a splenectomy, however, it was histologically found to be an IPT of the spleen.
