Splenic lesions are commonly discovered incidentally when imaging studies are performed for unrelated clinical reasons. Indeed, the increasing use of imaging studies has led to an increase in the detection of such incidental lesions and the differential diagnosis and management frequently is based entirely on their imaging features.  Most incidental splenic lesions are benign and most primary splenic masses are of vascular or lymphatic origin [2 – 5].  

Haemangioma is the most common benign primary tumour found in the spleen. Other splenic lesions include: cysts, hamartomas, lymphangiomas, or granulomas. Lymphoma is the most common malignant tumour involving the spleen [3, 4].  

Other than these entities, the differential diagnosis includes rare lesions, often with overlapping imaging features.   

Multimodality imaging of splenic masses can help the radiologist to approach them and MRI, in particular, provides crucial characterization of these lesions [6].  

Additional imaging or follow-up is only needed if the splenic mass is seen in association with other clinical findings [7].
