Sonography provided an accurate diagnosis in 10 preoperative studies and correctly showed the extent of the lesions in two postoperative examinations in a group of 12 children with surgically proven intraabdominal lymphangiomas. These masses typically contained anechoic fluid in one or more contiguous cystic loculations bounded by or containing one or more 1- to 2-mm thick septa. Thicker septa occurred in several cases with inflammation and/or accumulations of fatty tissue. Chylous or creamy fluid displayed fine diffuse echoes, whereas hemorrhage resulted in coarse echoes and/or solid masses. In two patients unusual renal involvement mimicked polycystic kidney disease. Typical sonographic appearances of lymphangioma may be radically altered by hemorrhage, inflammation, and unusual sites of involvement.
超声检查在一组12例经手术证实的腹腔内淋巴管瘤患儿的10例术前检查中做出了准确诊断，并在2例术后检查中正确显示了病变范围。这些肿块通常在一个或多个相邻的囊性区域内含有无回声液，由一个或多个1至2毫米厚的间隔界定或包含这些间隔。在几例伴有炎症和/或脂肪组织积聚的病例中出现了更厚的间隔。乳糜液或乳状液显示出细小的弥漫性回声，而出血则导致粗糙回声和/或实性肿块。在2例患者中，不寻常的肾脏受累类似于多囊肾病。淋巴管瘤的典型超声表现可能会因出血、炎症和不寻常的受累部位而发生根本性改变。
