PRIMARY NON-HODGKINS SPLENIC LYMPHOMA

Objectives: To describe the imaging, clinical and pathological feature s of primary splenic lymphoma using a strict definition, Methods: Of 2 1 cases, plain films mere available in nine, sonograms in 10 and CT in 16, We categorized the spleen as either normal, enlarged with no foca l defects (type 1), studded with miliary masses (type 2), containing m ultifocal masses of varying size (1-10 cm) (type 3) or containing a so litary large mass >5 cm without (type 4A) or with (type 4B) central hy podensity/anechoic areas. Results: Clinical presentations were left up per quadrant pain, weight loss and/or fever, One case was found incide ntally on CT, Fourteen were type 4A, three type 4B, four type 3 and no ne were type 1 or 2, Nine of 10 cases were hypoechoic. In 11/12 cases with enhanced scans, the lesions are hypodense relative to the splenic parenchyma, and in one case, the lesion was necrotic, Rim enhancement was seen in one case. Conclusion: Primary splenic lymphoma usually pr esents as a mass or masses rather than with splenomegaly alone, Splene ctomy may be required for diagnosis.
