Malignant large-cell non-Hodgkin's lymphoma of the spleen

Primary malignant tumours of the spleen are rare, with non-Hodgkin's lymphoma being the most common. A case of malignant large-cell lymphoma of the spleen in a patient with unexplained splenomegaly, is presented. There are very few previous reports on this condition in the radiological literature. The sonographic, computed tomographic and angiographic findings are described, with a brief review of the literature on this condition. Although there are no specific radiological findings to diagnose this condition, it has to be considered in the differential diagnosis of a solitary lesion in the spleen.
