摘　　要：目的回顾性分析儿童颈部淋巴管瘤的CT表现和CT诊断价值。方法9例淋巴管瘤中6例为囊性淋巴管瘤,3例为海绵状淋巴管瘤。螺旋CT平扫9例,平扫同时增强扫描3例。结果淋巴管瘤在CT表现为颈部边界清晰的囊性肿物,位于颈动脉间隙或颈外侧间隙,有明显占位效应,沿邻近疏松组织间隙蔓延生长。囊性淋巴管瘤表现为水样密度,密度均匀,有分隔,囊性区无强化,囊壁及分隔轻度强化。海绵状淋巴管瘤密度不均,可见低密度背景下等密度或略高密度的点片状和条状结构,CT增强扫描特征为低密度区无强化,囊壁及分隔呈点状、条状、网格状强化。结论CT检查可清晰显示淋巴管瘤的位置、形态、大小和蔓延范围,依据其部位、内部结构和CT特点可作出准确的定性诊断。Objective To retrospectively analyze the CT characteristics and its diagnostic value in children＇s cervical lymphangioma. Methods 9 cases with lymphangioma were investigated, out of them, 6 cases were cystic lymphangioma and 3 cases were cavernous lymphangioma. These 9 cases were scanned by spiral CT, out of them, 3 cases were enhanced. Results CT revealed cystic neck tumor with clear border localized in cervical carotid artery space or lateral space with an obvious mass effect, spreading to adjacent loose tissue. The CT findings of cystic lymphangioma were cyst with uniform density, water density with abjunctions, and no enhance in cystic area, but the wall of cyst and abjunctions were slightly enhanced. The CT findings of cavernous lymphangioma were uneven density, spot and lamellar or strip structures with even or slightly higher density under low density background. No enhance in low-density areas, but the wall of cyst and abjunctions were enhanced, Conclusion CT scanning can clearly show location, shape, size and spreading scope of lymphangioma, thus, accurate diagnoses can be made according to their locations, CT features and internal structures.
