The sonographic features of231ymphangiomas (19 pediatric patients) were compared with the pathologic findings . Nineteen Iymphangiomas appeared as unicameral (n = 2) and multiloculated (n = 17) cystic masses . R emaining lesions were inhomogeneously echogenic mass with small cystic portions (n = 3) and a mixed pattern (n = 1). Fourteen of the multiloculated tumors had thin septa and 6 had solid echogenic foci. The fluid within the majority of the cyst was anechoic in 8 cases and echogenic in 11
more » ... and echogenic in 11 cases . Correlation of the sonographic features with the pathologic findings demonstrated that the cystic spaces corresponded to the dilated Iymphatic spaces lined with endothelium , separated by septa. Echogenic f1uid represented hemorrhage . The echogenic components corresponded to clusters ofvery smaller dilated Iymphatic channels, thick fibro-fatty septa, or blood clot. The author' s experience suggests that the most characteristic sonographic appearance of Iymphangioma is a multiloculated cystic mass with thin septa, ref1ecting the preponderance of f1uid-filled spaces. An atypical appear ance usually reflects the presence ofblood or dominancy of cavernous type. The information obtained with US imaging can help in providing a preoperative diagnosis and in planning surgical resection .
