The sonographic findings in eight children with surgically proved cystic hygroma were reviewed and correlated with the pathologic specimens. Six tumors occurred in the neck, one occurred in the axilla, and one involved the soft tissues of the thigh, scrotum, and pelvis. A cystic hygroma characteristically appears as a multiloculated cystic mass with septa of variable thickness that contain solid components arising from the cyst wall or the septa. Correlation of the sonogram with the pathologic specimen demonstrated that the echogenic component corresponded to a cluster of abnormal lymphatic channels, too small to be resolved with ultrasound. Large lesions had ill-defined boundaries, with cystic components dissecting between normal tissue planes. Sonographically, one can usually differentiate these tumors from other cervical masses, especially soft-tissue hemangiomas. Sonography is also helpful in determining the extent of the lesion before surgery and in assessing postoperative complications and recurrences.
回顾了8例经手术证实为囊状水瘤患儿的超声检查结果，并与病理标本进行了对比。6例肿瘤位于颈部，1例位于腋窝，1例累及大腿、阴囊和骨盆的软组织。囊状水瘤典型表现为多房性囊性肿块，有厚度不一的分隔，分隔内含有起源于囊壁或分隔的实性成分。超声图像与病理标本对比显示，强回声成分对应于一簇异常淋巴管，因其过小而无法用超声分辨。大的病变边界不清，囊性成分在正常组织平面之间蔓延。在超声检查中，通常可以将这些肿瘤与其他颈部肿块，尤其是软组织血管瘤区分开来。超声检查对于术前确定病变范围以及评估术后并发症和复发情况也很有帮助。
