Abstract:
Objective To investigate the imaging features of splenic littoral cell angioma (LCA)and correlate with pathological findings.Methods Ten patients of LCA with pathologically confirmed diagnosis were included in this study.A retrospective review of clinical data and imaging findings on CT and MRI was performed,along with review of the literature.Results Splenic littory cell angiomas presented with multiple nodules of varying sizes with a predoninance of small ones.Nine of 10 patients had clinical symptoms of splenomegalia and hypersplenia.MR T2WI and DWI showed masses with high-signalintensity.The CT and MRI enhancing pattern of LCA was similar to splenic hemangioma.There were many mammiliform structures pointing inside in the wall of the vascular channels,a hallmark feature allowing its differentiation from splenic hemangioma pathologically.Conclusion The CT and MRI findings of LCA can show some of its characteristic signs,especially on DWI,which can assist to identify LCA in clinical practice.
