Results Among all 25 cases of lymphangioma,Within 20 cases of cystic lymphangioma,single cyst was showed in 14 cases and multilocular cyst was showed in 6 cases in plain scan,and little enhancement of capsule wall and septal in 8 cases in enhancement scanning. Cystic-solid mass was showed in 4 cases of cavernoma lymphangioma in plain scan,and solid part of mass was enhanced obviously in enhancement scanning.1 capillary ymphangioma showed the skin and hypodermic thicking,and part of area showed little beehive-like feature. Enhancement scanning showed slight irregularity enhancement.

结果 25例淋巴管瘤中20例囊性淋巴管瘤，CT平扫14例表现为单一囊肿，6例表现为多房性囊肿，囊腔内见有分隔；增强扫描8例出现囊壁或间隔的轻微强化。4例海绵状淋巴管瘤平扫均表现为囊实性肿块，增强检查实性部分有明显分期增强；1例毛细管型淋巴管瘤表现为局部皮肤及皮下组织的增厚，部分区域见有小蜂房样表现，增强扫描见有轻度不规则强化。
