Hemolymphangiomatosis of the spleen: imaging features.

abstract：:Cystic hygromas of the neck can simulate other benign lesions and occasionally extend into the mediastinum. Using computed tomography, we were able to confirm the suspected diagnosis, exclude other diagnostic considerations, and clearly demonstrate absence of mediastinal extension. ...
