CT manifestations of single splenic tumor or tumor-like diseases

Objective To explore the CT manifestations of single splenic tumor or tumor-like diseases.Methods Clinical manifestations and imaging characteristics of 18 cases with single splenic lesions confirmed by surgery and pathology were analyzed retrospectively.Results One of splenic hemangiomas was enhanced obviously and the other showed the selvage nodular enhanced.The edge and separation enhanced mildly in 3cases of splenic lymphangioma.Three large lesions of littoral cell angioma enhanced obviously at arterial phase and homogeneously at portal vein period,and then enhanced similar to surrounding tissue in delay period,the other 2showed the edge enhanced mildly.The characteristics of wheel-like calcification and enhancement was seen in three large cases of splenic sclerosing angiomatoid nodular transformation,and liquefaction necrosis was seen in another one.A lesion of splenic epithelioid hemangioendothelioma had no characteristic changes by CT scan.The vessel floating sign was seen in a huge splenic lymphoma at arterial phase,and 2splenic lymphoma enhanced mildly homogeneously.Conclusion CT could well demonstrate the size,shape,density,bordery and the enhancement of solitary splenic lesions.Single splenic tumor or tumor-like diseases could be diagnosed accurately by contrast-enhanced CT.
