Abstract
When a mass of the left upper quadrant is suspected on clinical or routine roentgenographic examination, and a space-occupying lesion of the spleen is seen on isotope study, selective abdominal angiography should be the preoperative diagnostic method of choice. The stretching and compression of vessels, seen in the arterial phase, and avascular zone(s) seen in the parenchymogram, are characteristic findings for the cystic lesions in the 4 cases presented. The angiographic appearance of lymphangioma of the spleen is reported here for the first time; it is unique and should allow for accurate preoperative diagnosis.
