Solitary lymphangioma of the spleen: dynamic MR findings with pathological correlation

Solitary lymphangioma of the spleen is an extremely rare, benign vasoformative tumour that typically shows no notable enhancement on imaging studies. Few descriptions of the MRI features have been reported and, to our knowledge, the findings on dynamic gadolinium-enhanced MR images have never been described. We report a case in which MR images showed diffuse and prolonged enhancement of a splenic mass. On histological correlation, splenic lymphangiomas with abundant fibrous stroma may account for this specific enhancing pattern.
