ABSTRACT

Objective To evaluate the value of CT and MRIin diagnosis of littoral cell angioma(LCA) of spleen.Methods CT and MRI findings the data of 6 patients with LCA were rospectively analyzed,and all patients were proved LCA of spleen by pathology.Then enhanced CT (n =4 cases) and MRI (n =2 cases) were performed.The imaging performance of LCA was observed,and its imaging features was summarized.Results None of patients showed obvious signs and symptoms of hypersplenism,4 cases were with splenomegaly.5 patients had a single lesion,only one had few lesions.There were not any calcification or envelopement of all the lesions.On CT,all lesions demonstrated distinct borders.The enhanced scan for low-density nodules demonstrated slow progressive enhancement.On MRI,all the LAC had well circumscribed borders,and demonstrated T1 · hypointense and T2-equal,hyperintense signals,and progressive enhancement on the post contrast images.Conclusion CT and MRI imaging of littoral cell angioma of spleen have special imaging characteristics,those particular findings is helpful in the diagnosis.
